Latest Patents

Takanori Simamoto holds a patent for a method of producing a contact hole in a semiconductor device. This method involves forming an LOCOS film on a silicon substrate, followed by the creation of a gate oxide film and gate electrode. Source and drain impurities are ion implanted into the silicon substrate using the gate electrode as a mask. A BPSG film is then formed, and a recessed part is created through a photolithographic process. The BPSG film is fluidized by reflow treatment to shape the contact hole into a funnel with an upwards convex curvature. This innovative approach helps prevent wiring disconnection and improves the controllability of impurity diffusion depth.
