Abstract:
1. A semiconductor device, comprising: a semiconductor substrate having a surface and defining a via hole therein through the surface; a first electrode over the surface of the substrate; a set of one or more transistor element(s) over the surface of the substrate, each transistor element in the set comprising at least one contact that is electrically connected to the first electrode, wherein the set of transistor element(s) compactly surrounds the first electrode and the via hole; a first and a second feed each having a respective tree-structure for balancing a respective feed signal, each transistor element having at least one contact that is electrically connected to the second feed; an insulating layer disposed on the first electrode; a third electrode disposed on the insulating layer and a metal connection that electrically connects a second electrode to the third electrode, each transistor element having at least one contact that is electrically connected to the second electrode.
