Abstract:
A method of fabricating a solid state image sensor device on a semiconductor substrate, the method comprising the steps of:forming a well region in the semiconductor substrate; forming a horizontal charge transmission region in the well region; forming a plurality of insulating layers in the horizontal charge transmission region; forming a gate insulating layer on the entire surface of the substrate including the insulating layers; forming a plurality of first polygates on the gate insulating layer, the first polygates being separated from each other and overlapping a portion of each insulating layer; forming a plurality of impurity regions in the horizontal charge transmission region at both sides of each first polygate; forming an interlayer insulating layer on the entire surface including the first polygates; and forming second polygates on the interlayer insulating layer to overlap a portion of each first polygate.
