Abstract
A semiconductor device with improved reliability is provided. The semiconductor device is characterized by its embodiments in that sloped portions are formed on connection parts between a pad and a lead-out wiring portion, respectively. This feature suppresses crack formation in a coating area where a part of the pad is covered with a surface protective film.
