Dielectric etching equipment are the specialised equipment which are used in the semiconductor industry for the specific purpose of etching dielectric material during the manufacturing process of a semiconductor. Dielectric etching process refers to an anisotropic process which removes various dielectric substances such as silicon nitride, silicon oxide and different overlying photoresist mask. Increasing demand for the high performance electronic gadgets and miniaturization of semiconductor circuits is expected to remain key growth driver for di-electric etching equipment during the period of study.

In a process known as silicon Wafer Inspection and cleaning, particles on the surface must be removed from the surface. The process of silicon Wafer Polishing starts with removing any defects. If new material is used to produce a silicon wafer, it can create roughness on the surface. This is an important step in the process before a wafer reaches the fabrication facility (fab).

Wafer manufacturing is a demanding job which needs specialized equipment as well as qualified staff to make wafers. At silicon specialist, we offer high-quality Silicon Wafers Manufacturing CA.
