Single Side Polished wafers for wide range of applications
Our customized Single Side Polished (SSP) wafers supply a perfect platform for Discrete&Analog applications, surface MEMS, capping etc. Okmetic’s in-house crystal growing creates unparalleled capabilities for the SSP wafers and thus customer’s processes.
Crystal groving provides the foundation also for our highly doped, low-resistivity wafers that enable extremely high performing power semiconductors. Our red phosphorus wafers boast ultra-low resistivity values that reduce the on-resistance and power losses of low-voltage power MOSFETs.
