Semiconductor Manufacturing Techniques | Solid-state Device

Silicon. Silicon is the second most common element in the Earth’s crust in the form of silicon dioxide, SiO 2, otherwise known as silica sand. Silicon is freed from silicon dioxide by reduction with carbon in an electric arc furnace. SiO 2 + C = CO 2 + Si

Refining Silicon

Silica is the dioxide form of silicon (SiO 2) and occurs naturally in the form of quartz. While beach sand is also largely quartz, the most common raw material for electronic grade is high purity quartz rock. Ideally the silica has low concentrations of iron, aluminum and other metals.

Silica Statistics and Information

Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses.

The most common constituent of sand, in inland continental settings and non-tropical coastal settings, is silica (silicon dioxide, or SiO 2), usually in the form of quartz, which, because of its chemical inertness and considerable hardness, is the most common mineral resistant to weathering.. The composition of mineral sand is highly variable, depending on the local rock sources and conditions.

Silicon Wafer Manufacturing | A Brief Overview of Wafer

Wafer fabrication involves building integrated circuits on silicon wafers, but before that, silicon wafer manufacturing must first take place. Silicon wafer manufacturing begins with a raw silicon or silica sand processed to attain highly pure silicon ingots. There are two ways to do this: CZ or Czochralski method and FZ or Float Zone method.
