Each wafer integrates hundreds of chips, and each chip consists of thousands of cells. So, how to make a cell? First step: Injection mask. The wafer is cleaned at first, a layer of silicon oxide film is deposited, and then a photoresist pattern is formed through uniform glue, exposure, ...
How to strengthen the blade shape and how to produce a complex blade shape in the silicon waferOphthalmic surgical blade, polycrystalline material or a single crystal, it is preferably made from polycrystalline or single crystal material in the form of a wafer. By attaching the polycrystalline ...
The surface of the silicon wafer is polished to create a mirror finish.Process the surface to make semiconductorsAn oxide film is grown onto the wafer. A photoresist film is coated on the wafer surface.The photoresist film is exposed to ultraviolet (UV) light through the pattern on the mask...
Wafer fabrication is a process of steps to grow an ingot, then slice, lap, etch, polish etc. They are used in semiconductors et al.

Silicon smelting: It is done at the 12-inch/300mm wafer level, and the same is done below. Through multi-step purification, silicon can be utilized for semiconductor production; the technical designation is electronic-grade silicon (EGS), and there is only one impurity atom per million silicon...
“I would say that lead time for wafer fab and test equipment is the biggest challenge, and I’d say this is across the board for all semiconductor equipment,” Hyndman said. “This is due to the surge in demand across the world for semiconductors in general, both traditional silicon and...
high-temperature operation. But it is not only the device’s properties that make curious for new designs and the future its also the strategy of STMicroelectronics. Silicon Carbide (SiC) technology is part of strategy at STMicroelectronics, STPOWER, to invest in wide bandgap (WBG) technologies...
Well, in this video, we're going to take a tour of a microchip fabrication plant or fab and walk you through the dozens of steps used to make a microchip. Specifically, we focus on how CPUs are made. CPU, GPU, and Smartphone Microchip manufacturing is a multi-trillion dollar industry,...
Because silicon wafers are susceptible to grounding, robots operate the wafers in more than 800 jobs, which takes more than a month to finish. As the wafers travel through the cycle, many layers of materials are added to the semiconductor wafer. ...
