Latest Patents
Yongxia Zhang holds a patent for a "Scanning force microscope thermal microprobe." This invention is a small bimetallic thermocouple probe device designed for use in scanning atomic force microscopy. The manufacturing process involves etching and oxidatively sharpening silicon points on a standard silicon wafer. The sharpened points undergo oxidation, followed by the deposition and patterning of the first thermocouple metal layer. The intermetal dielectric layer is then deposited and selectively removed at the probe tip using a double spin photoresist process. The exposed tips have the dielectric etched, and the second thermocouple metal is deposited and patterned. Finally, the finished thermocouples are produced by etching the silicon from the back side of the wafer, freeing the cantilevered structure upon which the probes are constructed. This innovative procedure allows for the inexpensive mass production of tiny, low thermal mass scanning atomic force microscope thermocouple probes.
