How is a computer chip created? Microchips are made by building up layers of interconnected patterns on a silicon wafer. The microchip manufacturing process involves hundreds of steps and can take up to four months from design to mass production.
What material is a microchip made of? Silicon is the material of choice in the chip industry. Unlike the metals normally used to conduct electrical currents, silicon is a ‘semiconductor’, meaning that its conductive properties can be increased by mixing it with other materials such as phosphorus or boron.
Does the US have the raw materials to make computer chips? Because of all of its manufacturing experience, TSMC now makes 92 percent of the most advanced semiconductors — that is, the chips that have transistors less than 10 nanometers wide — on the market today. None of these advanced chips are currently made in the US, which makes officials very worried.
How are computer chips made so small? In production, transistors are “printed” on a silicon wafer through a complex process called lithography. To produce the 7 nm chip, the team employed a new type of lithography in the manufacturing process, Extreme Ultraviolet, or EUV, which delivers huge improvements over today’s mainstream optical lithography.
