Patent ID: 7745859

Claim:
A solid-state image sensing apparatus comprising: first and second signal storage portions of a second conductivity type provided within a semiconductor substrate or a well each of a first conductivity type to store a signal charge obtained through a photoelectric conversion; a first surface shield layer of the first conductivity type provided in a surface portion of the semiconductor substrate or the well which is located above the first signal storage portion; a second surface shield layer of the first conductivity type provided in a surface portion of the semiconductor substrate or the well which is located above the second signal storage portion; a first gate electrode provided over the semiconductor substrate or the well in adjacent relation to at least one end of the first signal storage portion; a second gate electrode provided over the semiconductor substrate or the well in adjacent relation to at least one end of the second signal storage portion; a drain region of the second conductivity type provided in a surface portion of the semiconductor substrate or the well which is located between the first gate electrode and the second gate electrode; a first read control layer of the first conductivity type provided in a surface portion of the semiconductor substrate or the well which is located under the first gate electrode in adjacent relation to one end of the first surface shield layer; and a second read control layer of the first conductivity type provided in a surface portion of the semiconductor substrate or the well which is located below the second gate electrode in adjacent relation to one end of the second surface shield layer, wherein the first signal storage portion overlaps the entire first gate electrode and at least a part of the drain region, and the second signal storage portion overlaps the entire second gate electrode and at least a part of the drain region.
