Latest Patents

Hsiung's latest patents include a method for fabricating a titanium nitride sensing membrane on an extended gate field effect transistor (EGFET). This innovative method involves depositing a layer of aluminum on the gate terminal of the EGFET using thermal evaporation. The titanium nitride sensing membrane is then formed on an exposed part of the aluminum layer, serving as an ion-sensitive sensor, specifically a pH sensor. The use of titanium nitride is advantageous as it is compatible with standard CMOS processes, allowing for mass production and offering benefits such as low cost, high yield, and high performance.

Another significant patent by Hsiung is a method for fabricating a monolithic chip that includes multi-sensors capable of detecting pH, temperature, and photo-intensity simultaneously, along with a readout circuit. This method reduces chip area and cost by utilizing selection switches to sequentially read the sensor values within a clock cycle. The entire structure is fabricated using standard 0.5 µm CMOS IC technology, enabling the integration of on-chip signal conditioning circuitry. This innovative chip not only senses pH, temperature, and light values but also applies the EGFET for temperature and light compensation to produce accurate pH readings.
