Silicon wafers form the foundation of modern electronic devices. The Czochralski (CZ) Method is the most common way to grow silicon ingots. SQI offers prime- and test grade CZ Silicon in a wide range of standard and custom parameters.

The Float Zone (FZ) Method produces a highly pure form of silicon. The purity of the material allows for lower defect concentrations and higher resistivity levels and it is useful in high-power devices, detectors and solar applications. SQI offers the very best Float Zone material commercially available, not made from CZ re-melts but from high-quality polysilicon, thus allowing for resistivity’s in excess of 10k ohm –cm. Silicon Quest is the exclusive representative for Topsil Float Zone Products in the USA.

Sapphire (A12O3) is a semi –conductor material that is widely used in the fabrication of light-emitting diodes (LEDs). SQI’s proprietary sapphire supply provides optical and mechanical grade substrates as well as ingots in all orientations and all sizes from 2” to 6” diameter.

SOI is a technology that bonds an active wafers to a handle wafer with an oxide layer in between. SQI offers a wide range of SOI products, suitable for a variety of applications.

Silicon carbide (SiC) is a material used in diodes, transistors and some LED applications. SQI’s exclusive supplier of silicon carbide wafers and ingots provides top-quality material.
