4inch Silicon wafer FZ CZ N-Type DSP or SSP Test grade

Short Description:

A silicon wafer is a thin sheet cut from single crystal silicon. Silicon wafers are available in 2-inch, 3-inch, 4-inch, 6-inch, and 8-inch diameters, and are mainly used to produce integrated circuits. Silicon wafers are just the raw material and chips are the finished product. Silicon wafers are important materials for making integrated circuits, and various semiconductor devices can be made by means of photolithography and ion implantation on silicon wafers.

Silicon wafers are an integral part of today's growing technology sector. The semiconductor materials market requires silicon wafers with precise specifications to produce a large number of new integrated circuit devices. We recognize that as the cost of semiconductor manufacturing increases, so does the cost of those manufacturing materials, such as silicon wafers. We understand the importance of quality and cost effectiveness in the products we provide to our customers. We offer wafers that are cost-effective and of consistent quality. We mainly produce silicon wafers and ingots (CZ), epitaxial wafers, and SOI wafers.
