Latest Patents

Iwamoto holds a patent for an "Electronic device manufacturing method." This invention aims to provide a semiconductor device with a buried multilayer wiring structure that minimizes the generation of resolution defects in resist patterns. By reducing defective wiring caused by these defects, his method improves the overall quality of semiconductor devices. The process involves forming a via hole that reaches an etching stopper film, followed by annealing at temperatures between 300 to 400°C. This annealing can be performed using either a hot plate or a heat treating furnace. To protect the lower wiring that has already been manufactured, the heating is conducted for a brief period of approximately 5 to 10 minutes using the hot plate. This method effectively discharges by-products that may remain at the interfaces of various films, thereby decreasing the amount of residual by-products.
