Latest Patents

Among his latest patents is a method for pre-shaping a semiconductor substrate for polishing. This innovative approach involves shaping the major surface of a semiconductor wafer to have a concave shape, which is achieved through an etching process. This concave shape ensures that the starting wafer is extremely flat after polishing. Another significant patent is for a single crystal ingot and the method for growing the same. In this process, a single crystal seed is inserted into a melt and pulled at a high rate to grow a single crystal neck. The pulling rate is then adjusted to create an overhang with a larger diameter, which helps alleviate stresses in the single crystal neck.
