Latest Patents
One of his latest patents is for a "Low pressure stagnation flow reactor with a flow barrier." This invention features a flow barrier designed to achieve uniform reactions across the surface of a workpiece, such as a semiconductor wafer, in a stagnation flow reactor operating under low pressure or low flow rate conditions. The flow barrier is typically shaped like an annulus and can include passages or flow channels for directing a secondary flow of gas at the surface of the semiconductor workpiece. The materials used for the flow barrier are chemically inert to the reactive gases flowing over the workpiece.
Another notable patent is the "Heating device for semiconductor wafers." This apparatus is designed for heat treating semiconductor wafers and includes an assembly of light energy sources that emit light energy onto the wafer. The positioning of these light energy sources creates various radial heating zones on the wafer. In one embodiment, the light energy sources are arranged in a spiral configuration, while in another, they are randomly dispersed. Additionally, concentric rings of light energy sources can be formed, with tuning light sources placed between them.
