Patent ID: 7867837

Claim:
A process for producing polysilicon electrodes on semiconductor components, comprising the steps of: (a) applying a polysilicon layer on a top side of a substrate; (b) applying an auxiliary layer to the polysilicon layer; (c) applying a layer made of photoresist to the auxiliary layer, and patterning the photoresist layer to form a resist mask; (d) patterning the auxiliary layer in a manner corresponding to the lateral dimensions of the resist mask; (e) providing the auxiliary layer with lateral hollowed-out recesses; and (f) after step (e), etching the polysilicon layer using the resist mask and the patterned auxiliary layer in order to form a polysilicon electrode having rounded edges, wherein the auxiliary layer is BARC WIDE 15 antireflection layer material and a hot plate temperature of 172° C. to 178° C. is set.
