Title: John W Medernach: Innovator in Silicon Technology
Introduction
John W Medernach is a notable inventor based in Albuquerque, NM (US). He has made significant contributions to the field of silicon technology, holding a total of 4 patents. His work primarily focuses on electrochemical methods that enhance the properties and applications of silicon materials.
Latest Patents
One of his latest patents is titled "Electrochemical thinning of silicon." This invention involves the formation of porous semiconducting material, such as silicon, through electrochemical treatment in hydrofluoric acid, using the specimen as an anode. The process allows for masking the specimen before treatment, leading to various outcomes such as thinned specimens or patterned thinned specimens. The thinned silicon can then undergo tests, including the measurement of interstitial oxygen using Fourier transform infra-red spectroscopy (FTIR).
Another significant patent is the "Electrochemical method for defect delineation in silicon-on-insulator." This method enables the identification of defects and metal contamination in thin-film silicon-on-insulator (SOI) or silicon-on-sapphire (SOS) wafers. By controlling the voltage of the silicon wafer's surface within a specified range and contacting it with an electrolyte, defects can be effectively delineated after the electrolyte is removed.
