Title: Solid-state image sensing device
Inventor: TERANISHI SHINICHI
IPC: H01L27/148
Filed: 1993-11-30
Abstract: PURPOSE:To shorten the channel of a transfer gate without increasing impressed voltage in an interline transfer CCD image sensor. CONSTITUTION:The inside of the semiconductor of a transfer gate 3 for controlling charge transfer from a storage region 9 to a buried layer 9 is composed of a threshold control region 15, a punch through region 18, a punch through prevention region 19, a P well 8, and an n-type semiconductor substrate 7 arranged from the side of the surface. The acceptor concentration of the punch through region 18 is made smaller than those of the threshold control region 15 and the punch through prevention region 19. Namely, the distribution of the depth-direction acceptor concentration has a minimum. And this structure makes low-voltage operation possible since the vicinity of the minimum becomes a channel by punch through.
