Title: Innovations by Ramakrishnan Rajagopal
Introduction
Ramakrishnan Rajagopal is a notable inventor based in Singapore, known for his contributions to semiconductor technology. He has developed a unique method for forming a T-gate that enhances the salicidation process, which is crucial for modern electronic devices. His innovative approach allows for narrower bottom gate widths and wider top gate widths, facilitating improved silicide gate contacts.
Latest Patents
Ramakrishnan holds a patent titled "Method for forming a T-gate for better salicidation." This patent describes a comprehensive process that begins with the formation of a dummy gate composed of insulating material over a substrate. The method includes the creation of LDD regions adjacent to the dummy gate through ion implantation. Following this, a pad oxide layer and dielectric layer are formed, with the dielectric layer over the dummy gate being removed via a CMP process. The dummy gate is then eliminated to expose the substrate surface, allowing for the formation of a gate dielectric layer. A polysilicon layer is patterned to create the T-gate, followed by the formation of source/drain regions and a silicide layer to establish contacts. This innovative method significantly enhances the performance of semiconductor devices.
