In spite of this fact, advanced SiC devices, such as GTOs and IGBTs have been reported [1,2], the commercial SiC power switch development is still confined to the basic framework of VJFET, MOSFET, and BJT devices because of the present state of processing technology [3-9].
Self-aligned techniques can also be employed to reduce the extrinsic base resistance in order to improve conduction and switching performance of power SiC BJTs; • Interface-related issues causing poor channel mobility in MOSFETs and short surface minority carrier lifetime in BJTs require serious surface engineering, which may involve using alternative gate and field dielectrics, the introduction of a stable surface charge, or other approaches; • Reduction of p-type ohmic contact resistance is important to improve switching performance of power SiC BJTs by reduction of the base resistance; • Development of an efficient and reliable edge termination and passivation techniques will allow for the thinner and higher doped voltage blocking regions which will further decrease both onstate and switching power losses; • The continued work toward integration of different types of devices on the same chip may finally lead to a fully integrated voltage controlled SiC switch.
