Claim Text:
1. A semiconductor apparatus, comprising: a first element part including a first semiconductor layer provided with a first transistor: a first wiring part including a first conductor layer arranged on the first semiconductor layer, and a first insulator layer arranged between the first semiconductor layer and the first conductor layer; a second element part including a second semiconductor layer provided with a second transistor: a second wiring part including a second conductor layer, and a second insulator layer arranged between the second semiconductor layer and the second conductor layer, the second wiring part being arranged between the first element part and the second element part and between the first wiring part and the second element part; a third insulator layer arranged between the first conductor layer and the second conductor layer; and a conductive member connecting the first conductor layer with the second conductor layer, wherein the conductive member has a through part penetrating through the first semiconductor layer, the first insulator layer, and the third insulator layer, wherein the through part has a region mainly containing copper, and a conductive layer arranged at least between the region and the first semiconductor layer, between the region and the first insulator layer, and between the region and the third insulator layer, the conductive layer of the through part being in direct contact with the third insulator layer and the first insulator layer, and wherein the conductive layer mainly contains at least one of tantalum, tantalum nitride, tantalum carbide, titanium, titanium nitride, titanium carbide, tungsten, tungsten nitride, tungsten carbide and manganese.
