Latest Patents

Furukawa's latest patents include a method for manufacturing semiconductor integrated circuit devices. This innovative process involves forming Metal-Insulator-Semiconductor Field-Effect Transistors (MISFETs) with gate insulating films of varying thickness on the same substrate. The method effectively suppresses the formation of undesirable natural oxide films at the interface between the semiconductor substrate and the gate insulating film. Specifically, the gate insulating film for MISFETs in internal circuits is made of a silicon oxynitride film, while the I/O circuit MISFETs utilize a laminated silicon oxynitride film combined with a high dielectric film. This process is carried out in a multi-chamber treatment apparatus, ensuring that the substrate remains free from air exposure, thereby minimizing the risk of foreign matter contamination and natural oxide film formation.
