Title: The Innovations of William A. Bonner
Introduction
William A. Bonner is a notable inventor based in Warren, NJ (US). He has made significant contributions to the field of semiconductor materials, holding a total of 3 patents. His work primarily focuses on the minimization of strain in single crystals and the production of high-quality single crystal materials.
Latest Patents
One of Bonner's latest patents is titled "Minimization of strain in single crystals." This invention addresses the challenges associated with internal stress in grown crystals, which can lead to breakage during wafer cutting. The method involves a post-growth annealing step where pressure is significantly reduced, ideally to a level that does not exceed 50 percent of the pressure at which a constituent of the liquid body volatilizes. This technique is particularly beneficial for producing high-quality doped or undoped InP, GaP, and GaAs single crystals.
Another significant patent by Bonner is "Production of single crystal II-V material." This invention focuses on the fabrication of single crystals of III-V semiconductor materials, such as indium phosphide. Bonner discovered that twin formation can be prevented by adjusting various processing parameters, including melt temperature and pull rate. Specifically, he found that the rate of diameter enlargement of a boule should not exceed 0.3577 times the increase in length during the pulling process.
