Product Description
Carrier wafers made of Glass and Monocrystal Quartz are essential components in Thin Wafer Handling Systems for the MEMS and semiconductor industries. As market demand drives wafer thickness reduction, these carrier wafers enable safe handling and processing of thin and ultra-thin wafers.
Glass and Quartz materials offer exceptional thermal stability and chemical resistance against acids and other processing chemicals. Their transparent nature allows for effective monitoring during bonding and de-bonding processes.
