Title: Joseph D'Souza: Innovator in Semiconductor Technology
Introduction
Joseph D'Souza is a prominent inventor based in Sunnyvale, CA (US). He has made significant contributions to the field of semiconductor technology, particularly in the development of advanced materials and processes. With a total of 3 patents to his name, D'Souza continues to push the boundaries of innovation in his industry.
Latest Patents
One of D'Souza's latest patents focuses on methods and apparatus for producing stable low k fluorinated silicate glass (FSG) film for high-density plasma chemical vapor deposition (HDP-CVD). This invention allows for the deposition of FSG in a manner that ensures strong adhesion to both overlying and underlying barrier layers or etch stop layers. The resulting film exhibits a lower dielectric constant, which is beneficial for various applications. In this process, silicon tetrafluoride (SiF), oxygen (O), and argon (Ar) are utilized as reactant gases, with a controlled ratio of oxygen to silicon maintained between approximately 2:1 to 6:1. This careful control helps mitigate the degradation of ceramic chamber components that can occur due to the elimination of silane from the recipe.
