Latest Patents

One of his latest patents is focused on capacitors for high-temperature systems. This invention provides a capacitor that includes a substrate made from silicon carbide material, a dielectric stack layer, a Schottky contact layer, and an Ohmic contact layer. The first layer is formed with aluminum nitride (AlN) epitaxially, while the second layer is formed with aluminum oxide (AlO). These materials allow the capacitor to maintain capacitance changes of less than 10% between −250° C. and 600° C, making it highly effective for high-temperature applications.

Another significant patent by Ghosh is the quantum structure getter for radiation-hardened transistors. This microelectronic device incorporates a quantum structure getter (QSG) to enhance its resistance to radiation. The device includes a conductive channel and a material stack with a capping layer, barrier layers, and quantum structures. The quantum structures are strategically positioned to form a quantum well charge getter, which effectively traps and confines electron-hole pair wave functions produced from ionizing radiation, thereby hardening the device against ionizing radiation.
