Title: The Innovations of Darrell Keith Thomas
Introduction
Darrell Keith Thomas is a notable inventor based in Kingston, TN (US). He has made significant contributions to the field of materials science, particularly in the development of methods for transferring thin films and creating defect-free silicon-on-insulator materials. With a total of 2 patents, his work has advanced the understanding and application of silicon carbide and silicon technologies.
Latest Patents
One of Thomas's latest patents is titled "Method for transfer of thin-film of silicon carbide via implantation and wafer bonding." This patent describes systems and methods for transferring a thin film through implantation, wafer bonding, and separation. The method involves implanting a source crystal with ions along a crystallographic channel at a temperature of at least approximately 200°C. This process forms a strained region and defines the thin film, which is then bonded to a target wafer before separating the two along the strained region. The advantages of this method include the preservation of electrical carriers in the crystal, leading to improved quality of the transferred thin film.
Another significant patent by Thomas is the "Processing method for forming dislocation-free SOI and other materials." This method prepares a silicon-on-insulator material with a relatively defect-free silicon overlayer. It involves implanting oxygen ions within a silicon body and subsequently implanting silicon ions to relieve strain without the need for an intervening annealing step. This innovative approach allows for lower processing temperatures compared to previous SIMOX processes, reducing the likelihood of strain-induced defects.
