Latest Patents

Dong Chen holds a patent for a "Tank probe for measuring surface conductance." This invention describes a highly sensitive, non-contact tank probe designed to measure the surface conductance of thin film structures. The tank probe incorporates inductor (L), capacitor (C), and resistor (R) circuitry, which is driven by a signal generator at the probe's resonant frequency. The conductance of a film structure specimen is determined by measuring the signal reflected from the tank probe and its respective frequency. This technology allows for the acquisition of various types of information, including film thickness, doping concentration, and the presence of defects. In one embodiment, the tank probe is formed of integrated circuits within a semiconductor substrate. Additionally, the invention includes a method for using the tank probe system to measure the conductivity of a material specimen.
