Abstract: Integrated circuits with III-N metal-insulator-semiconductor field effect transistor (MISFET) structures that employ one or more gate dielectric materials that differ across the MISFETs. Gate dielectric materials may be selected to modulate dielectric breakdown strength and/or threshold voltage between transistors. Threshold voltage may be modulated between two MISFET structures that may be substantially the same but for the gate dielectric. Control of the gate dielectric material may render some MISFETs to be operable in depletion mode while other MISFETs are operable in enhancement mode. Gate dielectric materials may be varied by incorporating multiple dielectric materials in some MISFETs of an IC while other MISFETs of the IC may include only a single dielectric material. Combinations of gate dielectric material layers may be selected to provide a menu of low voltage, high voltage, enhancement and depletion mode MISFETs within an IC.

Abstract: Test structures and methods for superconducting bump bond electrical characterization are used to verify the superconductivity of bump bonds that electrically connect two superconducting integrated circuit chips fabricated using a flip-chip process, and can also ascertain the self-inductance of bump bond(s) between chips. The structures and methods leverage a behavioral property of superconducting DC SQUIDs to modulate a critical current upon injection of magnetic flux in the SQUID loop, which behavior is not present when the SQUID is not superconducting, by including bump bond(s) within the loop, which loop is split among chips. The sensitivity of the bump bond superconductivity verification is therefore effectively perfect, independent of any multi-milliohm noise floor that may exist in measurement equipment.
