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 …

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…
