In electronics, a wafer (also called a slice or substrate) [1] is a thin slice of semiconductor, such as a crystalline silicon (c-Si, silicium), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and upon

Mar 4, 2019 · The wafer is coated with a material called a photoresist, which responds to the light and is washed away, leaving an etching of the CPU that can be filled in with copper or doped to form transistors. This process is then repeated many times, building up the CPU much like a 3D printer would build up layers of plastic.

Wafer fabrication is a procedure composed of many repeated sequential processes to produce complete electrical or photonic circuits on semiconductor wafers in a semiconductor device fabrication process.

Oct 9, 2014 · To make a computer chip, it all starts with the Czochralski process. The first step of this process is to take extremely pure silicon and melt it in a crucible that is often made of quartz....

Dec 28, 2024 · A wafer serves as the starting point for semiconductor production. Manufacturers create these thin, circular slices from semiconductor materials, most commonly silicon. Using photolithography and deposition techniques, they build integrated circuits (ICs) directly onto the wafer’s surface. Key Facts About Wafers:

May 24, 2022 · A wafer-scale CPU effectively combines the processing power of dozens or hundreds of computers into a single integrated circuit, driven by one power supply, all housed in a single chassis. Even better, you can still network multiple wafer-scale computers together to create a traditional supercomputer, but exponentially faster.

How a CPU Microprocessor Is Made. This is a quick tutorial to help you understand how microprocessors and other integrated circuits are made, or 'fabbed.' Starting from a chunk of silicon and resulting in a device with millions and millions of transistors that now run almost everything in your life. Making the Wafer

How a CPU Microprocessor is made. Etching. 1. Oxide. A layer of oxide is implanted on the wafer. This is most often done by exposing the wafer to steam at very high temperatures. 2. Photoresist. A layer of organic photoresist is applied. This is like film in a camera. 3. Masking. A mask is applied and UV light is shown through the gaps.

How a CPU Microprocessor is made. Many many chips can fit on one 300mm wafer. Once the wafer full of chips is made each chip is tested while stll on the wafer.

Jan 24, 2025 · Wafer fabrication is the process of creating semiconductor wafers, which are thin, flat discs made from materials like silicon or Gallium. These wafers serve as the base for making integrated circuits (ICs) that power virtually every electronic device.
