Test grade wafers come right below the prime grade wafers on the quality basis.

FSM offers silicon thermal oxide wafers. These are the silicon wafers which have been through either a Wet Thermal Oxide, or a Dry Thermal Oxide process, to “grow” a Thermal Oxide, or Silicon Dioxide (Sio2), layer on the surface of the wafer.

FSM provides 100mm and 150mm SiC wafers. With its hardness (SiC is the second hardest material in the world) and stability under heat and high voltage current, this material is being widely used in several industries.

FSM carries a wide selection of the highest quality SEMI standard glass wafers. FSM also offers custom designed glass pieces to meet your needs for any application.

FSM does offer wafer polishing solutions.

In addition, we also provide and customize various sizes of coated wafers, such as Thermal Oxide, PETEOS, Nitride, POLY, Cu, W, TiN, TaN, PR wafers, etc. We also offer customers customized services for Pattern wafer. Furthermore, we provide third-generation semiconductor products such as glass wafers and SiC wafers in various sizes and specifications.
