Latest Patents

Edward Duffy holds a patent for a "Method and apparatus to control surface texture modification of silicon wafers for photovoltaic cell devices." This invention provides a method and apparatus to modify the surface structure of a silicon substrate or deposited silicon layer in a controllable manner using gas only in an atmospheric environment. The process is suitable for creating photovoltaic (PV) wafer-based devices. The method involves several steps, including disposing the substrate on a moveable carrier, pre-heating the substrate, and moving it for etching through an atmospheric reactor. The etching process utilizes at least one etchant gas, selected from fluoride-containing gases and chlorine-based compounds, delivered at a controlled flow rate and angle. This innovative approach addresses the technical challenge of achieving high throughput dry etching at atmospheric pressure without the need for plasma.
