Latest Patents

Detlev A Gruetzmacher holds a patent for a comprehensive process for low temperature epitaxial growth. This patent describes a system and method for growing low defect density epitaxial layers of silicon on imperfectly cleaned silicon surfaces. The process utilizes selective or blanket deposition at low temperatures, specifically between 550°C to 850°C, using the APCVD method. The initial thin layer of silicon is grown from silane or disilane, followed by the growth of the remainder of the film from dichlorosilane (DCS). This innovative approach minimizes defects and allows for controlled n-type doping, which is not achievable in silane-based systems.
