Latest Patents
One of his latest patents is the "Active large area avalanche photodiode array." This invention features a large area avalanche photodiode device that includes a plurality of contacts formed on a bottom side, which are isolated from each other by various kinds of isolation structures. In one embodiment, a cavity is created in one layer of the avalanche photodiode that extends to a depletion region, which exists in the layer due to a voltage applied to the device. The contacts are strategically positioned adjacent to the depletion region, enhancing the device's functionality. Another embodiment involves forming a grid of semiconductor material as an isolation structure between adjacent contacts, which forms a p-n junction with the surrounding material, providing necessary isolation. The design ensures that adjacent contacts are electrically isolated through a combination of a p-n junction and a high resistivity depletion layer.
