Abstract

A lateral silicon carbide transistor (10) utilizes a modulated channel region (18) to form an accumulation region that facilitates a low on-resistance. A doped region of the channel layer forms a channel insert (14) that also lowers the on-resistance of the transistor (10). A damage termination layer (27) is utilized to facilitate providing a high breakdown voltage. Field plates (23,24) also assists in increasing the breakdown voltage and decreasing the on-resistance of the transistor (10).
