Introduction

Tung-Wen Hsieh is a notable inventor based in Miaoli County, Taiwan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approaches to solving complex engineering challenges.

Latest Patents

One of his latest patents is titled "Method of fine pitch bump stripping." This invention provides a method for removing dry film resist (DFR) from a fine pitch solder bump array on a semiconductor wafer. The process involves pre-soaking the wafer in a chemical bath and then turbulently exposing it to a chemical solution, both steps occurring in batch processing with the wafers positioned vertically. Following this, the wafers undergo a chemical spinning operation where a solution is dispensed from a spray nozzle while the wafer is spun horizontally. The spin speed is increased to enhance the physical removal of any residue, and deionized water rinsing along with spin-drying ensures a solder bump array free of DFR or other residuals.

Another significant patent is the "Method and apparatus for feeding exhaust gases to a wet scrubber." This invention describes an exhaust gas conduit designed to feed exhaust gases to a scrubber. The conduit features a self-cleaning device mounted inside, which dispenses a cleaning solvent onto the inside wall of the outlet end to prevent solid depositions. This innovative approach also includes a method for preventing solid depositions in the exhaust gas inlet port to a wet scrubber, utilizing the self-cleaning device to maintain efficiency.
