Title: Silicon carbide semiconductor device and manufacture thereof
Inventor: YAMAMOTO TAKESHI
IPC: H01L29/78
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To make feasible of avoiding the fluctuation in the threshold value voltage also raising the surge resistance level as well as avoiding the defective punch through. SOLUTION: The regions 3b in no contact with a surface channel layer 5 out of a base region 3 are formed of boron while forming the regions 3a in contact with the surface channel layer 5 of aluminum. That is, if the regions 3a in contact with the surface channel layer 5 are formed of aluminum in low diffusion coefficient, the fluctuation in threshold value voltage due to the diffusion of B can be avoided. On the other hand, if the regions 3b in no contact with the surface channel region layer 5 are formed of B in high activating factor and low activating energy, the surge resistance level can be raised. Furthermore, these regions 3b are formed of B in longer range, thereby making feasible of easily increasing the junction depth also avoiding the defective punchthrough.
