Patent ID: 7994418

Claim:
A monolithic module comprising: a first conducting layer abutting and covering at least one semiconductor layer abutting and covering a second conducting layer abutting and covering a substrate; a first trench penetrating through the first conducting layer to separate a first conducting layer for a first electrical device from a first conducting layer for a second electrical device; a second trench penetrating solely through the at least one semiconductor layer and the second conducting layer to separate a second conducting layer for the first electrical device and a second conducting layer for the second electrical device, wherein the second trench is at least partially filled with a resistive material; a third trench penetrating solely through the at least one semiconductor layer; and an electrically conductive interconnecting material at least partially filling the third trench and providing an electrical current pathway from the first electrical device first conducting layer to the second electrical device second conducting layer, wherein the second trench and third trench are within the boundaries of the first trench, and further wherein the second trench is spaced apart from and occupies an area that is different from the area occupied by the third trench.
