• 00:00 - 00:30 This could be the world’s cleanest factory. It’s at the cutting edge of human achievement where technology meets the future. And it’s constantly developing. If you cannot innovate you will not survive in this industry. They take silicon, one of the world’s most common materials
• 00:30 - 01:00 and stack billions of circuits and transistors on it. Their mission – to add billions more on chips that are always getting smaller. Everyday you need to do something new. If not, you are falling behind. In a world where everything depends on computing power tomorrow is being created right here inside this Mega Factory.
• 01:00 - 01:30 Monday morning. Peak time for water and power usage.
• 01:30 - 02:00 It’s critical. One glitch could spell disaster on the factory floor. We jokingly call it the 'Starship.' Because it looks like the captain's command room inside a starship. It serves as the brain of our factory operations controlling the entire facility's power systems water systems, air conditioning, and chemical management. Captain of this starship, Rex Lai.
• 02:00 - 02:30 He’s the one with all the responsibility making sure the supplies are constant, and reliable. In semiconductor manufacturing there are actually over a thousand processes. You can imagine that when one of these processes halts it's equivalent to the entire workflow coming to a halt and restarting it afterward is quite a challenging task. It’s more than challenging. A break in production can cost millions. It places this energy center in a crucial role
• 02:30 - 03:00 safeguarding the lifeblood of this semiconductor giant. At the heart of the process, silicon. The substance that makes microchips possible. Sometimes it conducts electricity sometimes it doesn’t depending on how a little electrical voltage is applied. Hence it’s called a “semiconductor.”
• 03:00 - 03:30 In semiconductor manufacturing we commonly refer to the components as transistors. Transistors essentially serve as switches and they can be used in digital systems where all signals are represented using 0 and 1. It may seem crazy but basically a chip is just a lot of switches. Yet, it's way more complex than it appears.
• 03:30 - 04:00 In integrated circuits a vast number of transistors these so-called switches are placed on a single chip. For example, the chips used in Apple's smartphones contain hundreds of billions of transistors. These microscopic switches are the basic components of all computing. Whatever you want your chip to do it’s the billions of transistors on board that make it possible.
• 04:00 - 04:30 The more transistors there are the more complex the computations possible and the more your device can do. From communications, computing, medial health and even military purposes they are basically the brains of modern electronics.
• 04:30 - 05:00 Taiwan punches above its weight when it comes to creating chips not least thanks to its long experience and its geographical location. Taiwan is extremely strong in the manufacturing sector. It holds nearly 70% of the global market share in foundry services over 90% in advanced fabrication processes and it also leads in assembling and testing at the global level.
• 05:00 - 05:30 Ranged across three science parks from the North to the central and down to the South of Taiwan there’s a dense cluster of facilities built to serve every stage of chip production. Taken together, they make Taiwan the most significant producer of semiconductors in the world.
• 05:30 - 06:00 Taiwan is the only location around the world that manufactures both the most leading-edge logic products and also the leading-edge memory. So the leading-edge logic obviously is produced by TSMC and the leading-edge memory is by Micron. At the center of the cluster is Micron Technology. one of Taiwan's largest semiconductor manufacturers.
• 06:00 - 06:30 The company was founded in the USA but it has also made itself a home in Taiwan with a vast factory performing the bulk of its manufacturing. It’s been here for nearly 30 years and is one of the reasons why the island has become pre-eminent in semiconductor production. The scale and magnitude of Micron Manufacturing in Taiwan
• 06:30 - 07:00 is just unparalleled. 25% of Micron’s employees work in Taiwan and we produce 65% of Micron’s DRAM and worldwide market share is about more than 10%. So a Mega Fab is yes but it’s not an overnight work. This is the factory: 1,000,000 square meters of production the size of 140 football pitches. The entire process takes place within these walls
• 07:00 - 07:30 from R&D, through fabrication, assembly and testing right through to sales. We have two manufacturing plants one in Taoyuan Kweishan the other one right here in Taichung Houli. I’m not gonna tell you how much it is but it’s a mega factory. Zhong Lian Bin has been working in semiconductor engineering for three decades
• 07:30 - 08:00 He’s a perfectionist and you have to be. He prides himself on getting everything right down to the last detail. Semiconductor manufacturing today is involving more than 1000 steps. We are not talking about just getting one step correct. We’re talking about getting all thousand over steps correctly lined up to be able to have functional chips.
• 08:00 - 08:30 The first step is design, a monumental task given that billions of transistors have to be fitted onto each tiny chip Semiconductor design is actually developing the architecture for integrated circuits.
• 08:30 - 09:00 So design is kind of like building a skyscraper. Architects and civil engineers will discuss about the high-level building plan where to put the utilities, how to lay out the rooms. Once the design is complete it’s sent to the fabrication area otherwise known as the Fab, where it will be made.
• 09:00 - 09:30 Getting in is not a simple process. There is one enemy that can never be permitted to enter dust. Not one particle can be brought in. It’s called ‘gowning’ but it’s not really a gown that they put on. They call it a bunny-suit but despite the funny name
• 09:30 - 10:00 it’s one of the most vital pieces of equipment in the factory. It’s designed to keep the dust, hairs and skin particles we shed the whole time from polluting the pristine factory floor. Even the furniture in the gowning room is designed to maximize cleanliness. It’s all made from stainless steel right down to the benches and shoe racks.
• 10:00 - 10:30 Once you’re tucked safely inside your bunny-suit there’s one more stage before you can finally enter the clean area. You need to take a special “shower.” Filtered air is blasted through dozens of vents removing any particulates that might have made it this far.
• 10:30 - 11:00 This is like half a minute out of one million years. That’s the amount of the control that we have to in order for us to be able to have successful wafer fabrications. The production line is a hundred times cleaner than any hospital operating room. But cleanliness is just a precondition.
• 11:00 - 11:30 The work is yet to begin. The machines here are some of the world’s most sophisticated without them, the technical advances made in the design rooms could not be made a reality. It all starts with a perfect, clean silicon wafer 12 inches across.
• 11:30 - 12:00 It’s spun at high speed. A few drops of a UV-sensitive liquid are enough to coat the wafer evenly. And then it’s into the photolithography machine. It’s a bit like the way photos used to be printed in a darkroom but in a machine costing a hundred million dollars and with the accuracy to match.
• 12:00 - 12:30 60 years ago, a transistor we were able to see using human’s naked eyes. Today, the size is in fact like almost 10,000 times smaller than a human hair. That’s a huge amount of innovation especially coming from photolithography in order for us to print or define such small patterns onto the wafers. Inside the machine
• 12:30 - 13:00 the wafer is exposed to UV light projected through a mask carrying the design like a film negative. This light optically prints the circuit design onto the wafer causing exposed areas to solidify while unexposed ones are etched away. This process happens time and time again as the circuitry is built up in layers.
• 13:00 - 13:30 And with the pathways in the circuits measuring just a few nanometers the tiniest bit of contamination could disrupt the entire production line. The staff may be in their bunny-suits but the best way to keep the chance of contamination to a minimum is to keep the people out. To do that you need to automate whatever you can.
• 13:30 - 14:00 Getting machines to move the wafers about the factory floor not only keeps humans away from them but it also optimizes delivery efficiency. Loading machines take the printed wafers and place them in specialized containers. These containers are then hoisted up into little buggies running along overhead rails. With all this high-speed traffic
• 14:00 - 14:30 the little vehicles are covered in sensors so they can detect one another and regulate their speed if they get too close. There are thousands of them in this mega factory and together they travel nearly 400,000km every day the equivalent of circling the planet ten times. In the earliest days of semiconductors wafers were manually loaded onto machines by people.
• 14:30 - 15:00 Nowadays, with remote connections and automated material handling systems for delivery and retrieval the number of machines operated by a single person has increased from 10 to 30 or even more which was previously impossible. Altogether, there are thousands of huge machines on the factory floor. And as expensive and reliable as they are they still need constant monitoring.
• 15:00 - 15:30 Fortunately for purposes of keeping out contamination this can be done remotely. By a remarkably small crew located at the far end of the factory. Our factory currently operates with nearly 5000 units if we count in terms of units.
• 15:30 - 16:00 However on any single shift we rely on only 70 to 90 colleagues to accomplish this. So, in the semiconductor industry the role of people has essentially shifted from manual labor the role of people has essentially shifted from manual labor to knowledge-based and logical decision-making. Wolf Chen is in charge of this crew. They have to make sure that the hundred or so processes inside the clean area are all running to plan.
• 16:00 - 16:30 They have at their disposal over 50,000 sensors and 250 million control points. This results in an astonishing flow of data reaching up to 30 petabytes every single day. On the screens you can see several critical key indicators that come from consolidating and simplifying a mass of data. This allows everyone
• 16:30 - 17:00 to grasp today's production priorities straight away and identify any current issues within the factory. After the wafers have been tested 80% of the chip-making work is done. But now they meet their final challenge to be transformed into usable components.
• 17:00 - 17:30 Each wafer has had many chips printed onto it. Now they have to be separated. This is done by one of the oldest technologies in use here cutting with diamond blades. The individual chips are extracted and placed one by one onto circuit boards. Next, they have to be connected up
• 17:30 - 18:00 so that they can communicate with other components. Fine gold wire makes the connections placed by yet more precision machines. A silicon wafer itself is very fragile. If there’s any humidity, any corrosion in the environment it could damage the silicon chips. So the back-end process will encapsulate the silicon chip so that it’s able to protect against any kind of environmental damage as well as any kind of mechanical damage.
• 18:00 - 18:30 Once in their familiar black protective casing these chips are tested. Any that aren’t up to scratch are weeded out. Then, all qualified parts are laser-tagged so they can be readily identified. Now they’re ready to head out into the world and be put to use.
• 18:30 - 19:00 This extraordinary process has undoubtedly changed the face of the world and will continue to do so as it is refined and continues to develop. But, as with everything the benefits it brings come at a cost.
• 19:00 - 19:30 The process is always becoming more complex. In the past, simpler steps were needed now they need to be more intricate. So that means more water and electricity are required to complete a process. Back in the starship where the factory is kept running. Rex Lai and his team are attempting to mitigate the burden inevitably placed on the environment
• 19:30 - 20:00 by the demands of such a mega factory. We've installed the world's first chemical concentration system within our factory. Its purpose is to transform discarded isopropyl alcohol (IPA) into reusable raw materials making it attractive for buyers. They’re trying to achieve the same success with a range of other chemicals used in the chip-making process.
• 20:00 - 20:30 What at 15% concentration would previously have been sent for incineration can at 80% head out for recycling. The factory uses more water than any other resource a resource that is under increasing pressure worldwide. Clever treatment systems here at the factory reclaim nearly 80% of the water used dramatically reducing consumption.
• 20:30 - 21:00 We don’t just look at things horizontally. We’re taking a vertical approach too. So, in our new factory we've started planting vegetation on the walls creating green belts and generating 18,000 square meters of green space making huge improvements to our environment. These green walls help reduce the energy used to maintain the environment within the factory. And the use of renewable energy
• 21:00 - 21:30 saves the equivalent of the power used by a small town. We only give out chips and nothing else which means we try to leave as small environmental footprint as possible. You see the downside impact of global warming. We need to do our part and we’ll continue to do so in Taiwan as well. We are on a small island with limited natural resources. But through the collective effort of a lot of very smart people
• 21:30 - 22:00 we have managed to become essential to world production. This is certainly something to be proud of. The world of the semiconductor an exquisite fusion of art and science where precision and ingenuity intertwine in an intricate dance. Thanks to the ceaseless innovation and round-the-clock manufacturing within these mega factories
• 22:00 - 22:30 human civilization advances at light speed. So, the next time you send a text snap a photo or stream a video remember the extraordinary journey that propels us into the future one chip at a time.
