Abstract
Abstract Shunt wirings (12) in the form of a conductive light intercepting film which covers over vertical CCD registers and also serves to supply power, project into locations between adjacent photoelectric transducers (11) in the vertical direction, and the distance between the projecting portions of adjacent ones of the metal wirings is set to 0.2 μm or less and is limited to a distance with which an electric field between adjacent ones of the metal wirings is 10 7 V/cm or less and the adjacent metal wirings do not suffer from short-circuiting.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
147 words
A solid state imaging apparatus which includes a plurality of photoelectric transducers, vertical CCD registers for receiving and transferring charge of said photoelectric transducers via charge read-out regions, a horizontal CCD register for receiving and transferring charge from said vertical CCD registers, a charge detector for detecting charge from said horizontal CCD register, and an output amplifier for amplifying and outputting charge from said charge detector, and wherein metal wirings for supplying driving pulses to vertical transfer electrodes of said vertical CCD registers disposed vertically along said vertical CCD registers, and said metal wirings are formed having projecting portions in regions between adjacent ones of said photoelectric transducers in the vertical direction and the distance between the projecting portions of the adjacent ones of said metal wirings is 0.2 μm or less so that leakage of visible light between said projecting portions is reduced substantially to zero.
Claim 2
Dependent Claim
