Latest Patents
Chieh-Ju Chang holds a patent titled "Preventing gate oxide thinning effect in a recess LOCOS process." This invention relates to a method for preventing gate oxide thinning during the recess LOCOS process. The method involves the use of a plurality of trenches separated by a patterned pad oxide and a patterned silicon nitride layer. By removing these layers, the substrate's surface is exposed as an active area for the semiconductor device. The process includes an ion drive-in to the active area, utilizing a flow of oxygen and nitrogen at a predetermined temperature to prevent silicon nitride formation on the field oxide regions. Additionally, a sacrificial oxide layer is formed and subsequently removed to expose the active area, followed by the formation of a gate oxide layer.
