Latest Patents

One of his latest patents is titled "Current mirror methodology quantifying time dependent thermal instability accurately in SOI BJT circuitry." This invention provides a current mirror method that evaluates thermal issues in silicon-on-insulator (SOI) bipolar junction transistors (BJTs). The method significantly improves safe operating area (SOA) measurement sensitivity. Unlike conventional methods, it offers a quantitative analysis of the BJTs' thermal instability over a wide power range, even within the apparent SOA of the device. Additionally, it can predict and evaluate SOA concerning emitter ballast resistance and current crowding.

Another recent patent is the "Method for testing metal-insulator-metal capacitor structures under high temperature at wafer level." This test methodology is designed for assessing metal-insulator-metal (MIM) capacitor structures under high temperatures at the wafer level. It involves forming a resistor on a region of dielectric isolation material in a semiconductor substrate. The MIM capacitor is then formed over the resistor, separated by dielectric material. A metal thermometer, made from the same material as the capacitor plates, is placed above the resistor. By forcing high current through the resistor, both the thermometer and the MIM capacitor heat up. The change in resistance of the metal thermometer is monitored, allowing for temperature conversion based on the known temperature coefficient of resistance (TCR) for the metal used.
