A method to detect counterfeit integrated circuits through the use of a microwave resonator
TS-048646 — A novel method to detect a counterfeit integrated circuit (IC) and to authenticate an IC using the electromagnetic characteristics of the IC and a resonator
The presence of counterfeit integrated circuits (commonly referred to as “ICs” or “chips”) in a supply chain, such as a military supply chain, can result in either a failure of a critical system or a compromise of the data on that system. These counterfeit chips may not be …

Dielectric heterojunction device
TS-048644 — The potential of different materials for vertical power switching is often assessed by calculating the Baliga Figure of Merit (BFOM). In the case of wide and ultra-wide bandgap materials, the high breakdown fields and the relatively good transport properties make the BFOM significantly higher than…

A Lightweight Low Inductance Power Module with Insulated Baseplates
TS-048588 — A lightweight power module that reduces loop stray inductance while maintaining good electrical insulation and thermal dissipation.
In conventional power module structures, the die is attached to the substrate, usually direct bonding copper (DBC). The ceramic substrate layer provides electrical insulation between the circuit and cooling structure and attaches to a conductive baseplate material (Cu, Al, AlSiC) to dissipate heat…

Quantum Well Design for Red-Emitting InGaN LEDs
TS-042441 — The quantum well design is incorporated within a red-emitting InGaN QW LED, an LED type that usually cannot efficiently emit wavelengths larger than blue/green. The LED can be incorporated into a same-material RGB platform for white LEDs, because the well design increases efficiency and decreases indium composition compared to similar wavelength InGaN LEDs.
Blue-emitting InGaN quantum well (QW) LEDs now have 69% external quantum efficiency, but increasing the emitted-wavelength decreases the efficiency significantly. The inversion asymmetry of the InGaN lattice increases the induced strain, which in turn increases the piezoelectric effect. Charge bui…

Field Effect Transistor for High Power Millimeter-Wave Applications
TS-042088 — Transistor structure with high breakdown voltage at high frequency operation
A new generation of high throughput, efficient communication networks and sensors can be enabled through the use of millimeter scale wave regimes. However, current semiconductor materials (such as AlGaN/GaN) have a reduction in breakdown voltage as operating frequency increases, which leads to low…

Method to enhance light extraction efficiency in tunnel-injected III-Nitrate ultraviolet LEDs
TS-037365 — A novel method to enhance the transverse-electric and transverse-magnetic polarized light via relfective surfaces on top of a tunnel junction based LED structure.
III-Nitride ultraviolet light emitting diodes (UV LEDs) have a variety of promising applications, including sterilization and water purification. Currently, UV LEDs use an absorbing p-GaN top layer for hole injection, which reduces light extraction efficiency to lower than 20%. UV light emissions …

Off-Axis Sputtering Deposition System for Growth of Single Crystalline Films
TS-015210 — This innovative deposition system is able to grow single crystalline films of a broad range of complex materials with unprecedented crystalline quality of binary, ternary and quaternary oxides and intermetallics with simple or complex crystal structures.
Sputter deposition is one of the dominant techniques used in manufacturing films and coatings in many industries. Conventional sputtering uses an “on-axis” geometry, i.e., the substrate directly faces the sputter target. Due to the energetic bombardment of sputtered atoms, sputtering i…
