Stabilization of a patterned planarizing layer for solid state imagers prior to color filter pattern formation |
摘要 |
A solid state image sensor is described which includes a planarizing layer incorporated into a means of color separation. The planarizing layer has been found to provide a smooth, uniform surface for coating and adhesion of a color separator within the active device area. The planarizing layer remains on the completed device and is patterned to permit access to bonding pads. Negative photoresist materials, photoinitiated polymerization imaging systems and positive imaging systems may be selected for use as the planarizing layer.
