Latest Patents

Tsudumitani's latest patents detail a manufacturing method for semiconductor devices. In this process, a first film and a second film are sequentially formed on a semiconductor substrate. A resist pattern is then created on the second film, followed by the formation of an opening by removing the exposed second film between the resist pattern. A first removal preventing film is applied to the side wall of the opening, allowing for the removal of the residual film while maintaining the projecting part of the second film. The first film exposed in the opening is subsequently removed. A second removal preventing film is then formed on the first removal preventing film, allowing for the removal of the surface of the semiconductor substrate exposed in the opening while creating a rounded part at the projecting section. Finally, the semiconductor substrate exposed in the opening is further removed.
