Abstract:
1. A method for forming a CMOS image sensing pixel, the CMOS image sensing pixel being configured for determining a color, the method comprising: providing an n-type substrate, the n-type substrate including a first thickness and a first width; forming a p-type epitaxy layer, the p-type layer overlaying the n-type substrate, the p-type epitaxy layer including a second thickness and a second width, the second thickness and the second width being associated with a light characteristic; forming an n-type layer, the n-type layer overlaying the p-type epitaxy layer, the n-type layer including a third thickness and a third width; forming a pn junction between the p-type epitaxy layer and the n-type layer, the pn junction including a fourth width; and providing a control circuit, the control circuit being electrically coupled to the n-type substrate.
