Wafer carrier plates, ceramic, glass, quartz or sapphire

Carrier Plates for Semiconductor Wafers

Valley Design Corporation offers an array of carrier plates that are ideal mounting tools for dicing, lapping, polishing and thinning semiconductor wafers.

Wafer carriers can be manufactured out of a number of different materials ranging from Pyrex, BK7, Soda-Lime Glass and Quartz, to Alumina, Sapphire, Graphite or Fused Silica. These wafers are made to SEMI Silicon standard sizes and are available in 2", 3" 100mm, 125mm, 150mm, 200mm and 300mm diameter and as thin as 0.001". Surfaces may be lapped or polished to meet all optical specifications.

Sapphire carrier plates are currently available from stock, and are ready for immediate delivery. These wafer carriers can be used for processing Silicon, InP, GaAs and other semiconductor materials. They are semi-transparent and laser scribe identified. Sapphire wafer carriers are preferred for their durability, chemical and scratch resistance.
