Title: The Innovations of Roger W. Shaw
Introduction
Roger W. Shaw is a notable inventor based in Kirkwood, MO (US). He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work has focused on improving processes and apparatuses related to silicon crystal growth and semiconductor etching.
Latest Patents
One of Shaw's latest patents is an "Apparatus for controlling nucleation of oxygen precipitates in silicon." This innovative apparatus is designed for producing a silicon single crystal grown by the Czochralski process. It features a hollow growth chamber, a quartz crucible, and a pulling member that facilitates the upward growth of the silicon single crystal from a silicon melt. The design includes a crystal chamber that receives the crystal as it is pulled, along with heating members that prevent and control the formation of oxygen precipitate nucleation centers during the growth process.
Another significant patent is the "Method for etching a semiconductor material without altering flow." This method involves etching a generally planar surface of a semiconductor material to reveal flow pattern defects. By placing the material in a canted position and immersing it in a stagnant etchant solution, bubbles nucleating at flow pattern defects are released directly into the etchant, enhancing the etching process.
