Title: The Innovations of Raymond Joy
Introduction
Raymond Joy is a prominent inventor based in Singapore, known for his significant contributions to the field of semiconductor technology. With a total of 7 patents to his name, he has made remarkable advancements in the fabrication of enhanced-mobility pFET devices and wafer cleaning methods.
Latest Patents
One of his latest patents focuses on the prevention of faceting in epitaxial source drain transistors. This method involves fabricating enhanced-mobility pFET devices with channel lengths below 50 nm. The innovation allows gates for pFETs to be patterned in dense arrays on a semiconductor substrate that includes shallow trench isolation (STI) structures. Additionally, partially-enclosed voids in the semiconductor substrate are formed at source and drain regions for the gates, which are subsequently filled with epitaxially-grown semiconductor that compressively stresses channel regions below the gates. Some of the gates, referred to as dummy gates, extend over the edges of the STI structures to prevent undesirable faceting of the epitaxial material in the source and drain regions. Another notable patent involves apparatus and methods for cleaning and drying wafers. This includes a device with a first manifold and a second manifold, where the first manifold has multiple nozzles for dispensing chemicals onto the substrate, while the second manifold is connected to a vacuum source and/or a dry air/gas source.
