Latest Patents

Among Okada's latest contributions is his method of manufacturing a semiconductor device. This technique focuses on improving the reliability of semiconductor elements and their product yield by minimizing variations in the electrical characteristics of a metal silicide layer. The process begins with the formation of a nickel-platinum alloy film over a semiconductor substrate. A first thermal treatment is conducted at temperatures ranging from 210 to 310°C using a heater heating device. Through this treatment, the nickel-platinum alloy film reacts with silicon to create a platinum-added nickel silicide layer in a (PtNi)Si phase. Following the removal of any unreacted nickel-platinum alloy, a second thermal treatment at a higher temperature is executed to solidify the platinum-added nickel silicide layer in a PtNiSi phase. Notably, the temperature rise rates for both treatments are set to a minimum of 10°C/s, enabling effective thermal processing.
