WebHBT process, which consists of 3 metal layers, inter-layer Vias, semiconductor layers, and so on. See Fig. 2. The top metal (metal3) is used as a continuous ground plane for microstrip interconnects, so we cannot use this layer for interconnection. Pads for connection from the chip to the outside world are however also drawn in this layer. IC with complex circuits require multiple levels of interconnect to form circuits that have minimal area. As of 2024, the most complex ICs may have over 15 layers of interconnect. Each level of interconnect is separated from each other by a layer of dielectric. To make vertical connections between interconnects on different levels, vias are used. The top-most layers of a chip have the thickest and widest and most widely separated metal layers, which make the wires on those lay…
