Latest Patents

One of his latest patents involves a semiconductor device featuring a high-frequency bipolar transistor. This invention includes a bipolar transistor with a first main surface in contact with a conductive mounting surface, and an opposed second main surface equipped with connection pads for the emitter, base, and collector. The design ensures that the lateral dimensions of the conductive mounting surface are nearly equal to those of the first main surface, allowing for a compact structure. The high-frequency properties of the transistor are significantly influenced by the size of the conductive mounting surface, which forms a parasitic capacitance with a conductive ground surface. This capacitance is particularly important for high-frequency applications. Additionally, the bonding wires for the connection pads are shorter than in previous designs, resulting in lower self-inductance and resistance, which enhances the high-frequency performance and power supply capabilities.

Another patent details a method for manufacturing a bipolar transistor with emitter ballast resistors. This method involves creating a base window and a strip-shaped opening on a collector region, followed by doping the base after covering the strip-shaped opening with a masking layer. After the masking layer is removed, oxide layers of uniform thickness are formed in both the base window and the strip-shaped opening. The process continues with the formation of emitter fingers and base contact windows, leading to the creation of base contact zones and separated emitter ballast resistors.
