Solid-state image pick-up device and method for manufacturing the same

摘要

A solid-state image pick-up device having a structure in which the amount of transferred charges is not reduced in a vertical CCD portion even if a pixel portion is made finer, and a method for manufacturing the solid-state image pick-up device are provided. A first p-type well and a second p-type well are formed on an N (100) silicon substrate. A vertical CCD n+ layer is formed in the second p-type well 3. Then, impurity ions are implanted into a surface layer of the N (100) silicon substrate including an upper layer portion of the vertical CCD n+ layer to form a p- layer. An isolating portion for isolating photodiode portions from the vertical CCD n+ layer and a read control portion for controlling the read of charges from the photodiode n layer are simultaneously formed on a portion adjacent to the vertical CCD n+ layer.
