Wafers are found in pretty much all types of technology. A wafer serves the purpose of fabricating integrated circuits. When it comes to wafers, there are several different types available, all with distinct functions. Let’s take a look at some of the different types of wafers out there, including ultra flat wafers.
Polished Wafers – Polished wafers are silicon wafers with one or both sides polished to a mirror surface.Hi Wafer – A Hi wafer is a wafer that is heat treated in a hydrogen ambient. As a result, this wafer has an excellent gate oxide quality.
Diffused Wafers - Diffused wafers are employed in electric power control devices at a high rate. They then contribute to improving the efficiency of energy consumption.
Epitaxial Wafers - Epitaxial wafers are used to achieve surface integrity by putting various thickness epitaxial silicon layers. Thin versions are then commonly used for leading-edge MOS devices. On the other hand, thick and multi-layered versions are used for the devices mainly to control electric power.
SOI Wafer - SOI wafers are widely used in power devices and MEMS to achieve high breakdown voltage, low energy consumption and high performance of MEMS.
AT Wafer – AT wafers are heat treated in Argon gas ambient to prevent out-diffusion of dopant from the wafer surface and to have flat resistivity profile in depth.
At Wafer World, we offer a variety of wafers, including ultra flat ones. If you are looking for wafers for your next project, contact us today to learn more or to place an order.
