Patent ID: 7759758

Claim:
A semiconductor having a resistance temperature sensor comprising: trenches reaching from a surface of a semiconductor substrate into the semiconductor substrate, wherein adjacent trenches are isolated from one another by a mesa region of the semiconductor substrate; a first resistance structure formed within at least one of the trenches, wherein the first resistance structure at least partly adjoins an insulation structure for electrically insulating the first resistance structure from the semiconductor substrate and has at least two first connecting regions for making contact with the first resistance structure, the first connecting regions being electrically isolated from one another; a second resistance structure formed within at least one of the mesa regions, wherein the second resistance structure has at least two second connecting regions that are electrically isolated from one another; and wherein at least one of the first connecting regions is conductively connected to at least one of the second connecting regions, wherein the first resistance structure and the second resistance structure are connected in parallel with one another.
