With a total of 2 patents to his name, Vaidyanathan's work has had a lasting impact on electronic device performance.

Latest Patents

Vaidyanathan's latest patents focus on the design and method of self-aligned, planar heterojunction bipolar transistors. The first patent describes a process for forming an HBT with self-aligned base-emitter and base-collector junctions. This is achieved by creating a two-level mask over a doped base layer, allowing for precise openings that define the collector and emitter regions. A buried conductive layer, established through a dopant implant, ensures electrical contact to the collector region. The design minimizes parasitic capacitances by implanting the collector and buried conductive layers into a semi-insulating substrate, ensuring that only the active junction regions overlap.

The second patent reiterates the innovative method of forming self-aligned, planar heterojunction bipolar transistors. It emphasizes the importance of a thinner active base region, which reduces resistivity associated with connections to lateral base contacts. This advancement in HBT technology enhances the overall efficiency and performance of electronic devices.
