Processor Manufacturing

Jul 21, 2006The manner in which silicon is formed into chips is a lengthy process that starts by growing pure silicon crystals via what is called the Czochralski method (named after the inventor of the process). In this method, electric arc furnaces transform the raw materials (primarily quartz rock that is mined) into metallurgical-grade silicon.

Semiconductor terminology

Silicon – the raw material of the connected world. Silicon (Si) is the stuff of high-tech dreams. In the natural world, it is as common as sand on the beach – in fact, sand is mainly made up of silicon dioxide. To get the ultra-pure monocrystalline silicon needed for chip production, oxygen is extracted from the sand in a complex process.

Silicon, Silica, Silicates and Silicone

Silicon is a chemical element, one of the 97 natural building blocks from which our minerals are formed. A chemical element is a substance that can't be subdivided into simple substances without splitting atoms. Silicon is the second most abundant element in the earth's crust, making up about 27% of

VLSI and SEMICON

Step 2: Preparing the Molten Silicon Bath The sand (SiO2)is taken and put into a crucible and is heated to about 1600 degrees C – just above its melting point. The molten sand will become the source of the silicon that will be the wafer.

Can you turn glass back into sand?

Technically, natural sand is made of quartz crystals of silicon dioxide, whereas glass is the non-crystalline, amorphous form of silicon dioxide. But when it is ground down enough, the difference isn't obvious. Crushed glass is sold as an alternative to sand for pool filters – in fact, recycled crushed glass has been considered as a partial
