Latest Patents

Ming-Horn Tsai's latest patents include a method of fabricating sidewall spacers for a self-aligned contact hole. This method involves the formation of partial silicon nitride spacers on the sides of polycide gate structures through a partial anisotropic RIE procedure. The process results in a thin layer of silicon nitride remaining on regions between polycide gate structures. After the deposition of an overlying insulator layer, a two-step anisotropic RIE procedure is employed to create the SAC opening in both the insulator layer and the underlying thin silicon nitride layer. The first step selectively removes the first insulator layer, while the second step selectively removes the thin silicon nitride layer.

Another significant patent by Tsai is a multiple exposure method for photo-exposing photosensitive layers upon a high step height topography substrate layer. This method begins with a high step height topography substrate layer that has a blanket conformal photosensitive layer formed on it. The process involves photo-exposing the blanket conformal photosensitive layer to create patterns on different regions of the substrate, utilizing varying photo-exposure conditions to achieve the desired results.
