Latest Patents
One of Schumacher's latest patents is titled "Method and apparatus for preventing reactive vapor backstreaming and backstreaming induced deposition." This invention addresses the challenge of delaying the reaction between two reactive gases during semiconductor manufacturing. The method involves surrounding the first reactive gas with a non-reactive gas to create an insulated environment, allowing for controlled flow into the second reactive gas. Additionally, a sweep gas is utilized to impart momentum to the insulated first reactive gas. The apparatus consists of three coaxial tubular members designed to introduce the necessary gases, making it suitable for installation in semiconductor device fabrication processes.
Another significant patent is the "Energy efficient process for continuous production of thin semiconductor." This invention presents an energy-efficient method for the continuous production of semiconductor matrices. It involves electrodepositing doped silicon or germanium films on metallic sheet substrates. The energy released during the electrodeposition process can be harnessed to regenerate the anode material used in the electrodeposition position, thereby enhancing overall efficiency.
