Latest Patents

One of his latest patents is focused on on-chip diplexed multi-band submillimeter-wave/terahertz sources. This invention involves a solid-state device chip that includes diodes capable of generating higher or lower frequency outputs through frequency multiplication or mixing of the input frequency. The novel on-chip diplexing design allows for the combination of multiple multiplier or mixer structures operating at different frequency bands within the 50-5000 GHz range on the same chip or waveguide. The design consists of a single-substrate multiplier chip with multiple structures, each containing Schottky diodes tuned to specific portions of the target frequency band. This results in a significant increase in bandwidth from the current state-of-the-art of 10-15% to at least 40%. Depending on the target frequencies, each subset of diodes can function as either a doubler or a tripler.

Another notable patent is the wafer-to-wafer alignment method. This invention utilizes a silicon alignment pin to align successive layers of components made in semiconductor chips and/or metallic components. The compressible structure of the pin allows it to fit into corresponding alignment pockets defined in the layers, facilitating the assembly of devices with layered structures. This method enables the creation of multilayer structures, enhancing the efficiency of device assembly.
