Demand continues to grow for SiC bulk wafers as a base substrate for next-generation power semiconductors.As a trump card for energy conservation, these (SiC bulk wafers) show promise for installation in electric automobiles, photo-voltaic power generation systems, as well as wind power generation systems, etc.On the other hand, high performance, low cost SiC bulk wafers are difficult to produce due to high temperature sublimation manufacturing methods.All SiC bulk wafers handled in Ceramic Forum have passed the strict quality inspections for use in device mass production.
Ceramic Forum began handling SiC bulk wafers manufactured by Norstel AB in 2011.Norstel AB SiC wafers are manufactured by the sublimation method, which has low dislocation (ultra-low TSD, low BPD), greatly contributing to device performance and yield improvement in comparison with wafers produced by other companies.
A spin-off venture from Sweden's Linkoping University, with a history of high achievement in SiC research. Currently, the largest Epi service provider in Europe. Started in 1993, based on joint SiC research from Sweden's Linkoping University and ABB Ltd., Norstel AB continued under the umbrella of Finland's Si wafer maker, Okmetic, until independence in 2005. In addition to the SiC epi furnaces for mass production and the single wafer epi furnace for R&D, Norstel AB has built a system for mass production supported by a great deal of evaluation equipment.
