Patent ID: 8008664

Claim:
A semiconductor component comprising: a substrate that comprises a crystalline semiconductor body; several CMOS transistors formed in the semiconductor body; insulation regions formed between the CMOS transistors for mutual electrical isolation that comprise field oxide regions or STI regions; an additional insulation region that has a larger surface area than the other insulation regions; a thin-film transistor with a gate arranged on the additional insulation region; a first polysilicon layer; and a second polysilicon layer, wherein both a gate of a CMOS transistor and a gate of the thin-film transistor are formed in the first polysilicon layer and therefore have the same layer thickness and crystal structure, wherein the thin-film transistor has a source, a body and a drain that are formed in the second polysilicon layer, which also serves for structural elements of the CMOS transistors, and wherein the source and drain of the thin-film transistor are formed on either side of the gate in the second polysilicon layer by a p + -type or n + -type doping.
