METHOD, APPARATUS AND SYSTEM TO PROVIDE CONDUCTIVITY FOR A SUBSTRATE OF AN IMAGE SENSING PIXEL |
摘要 |
Techniques for promoting conductivity in a substrate for a pixel array. In an embodiment, an isolation region and a dopant well are disposed within an epitaxial layer adjoining the substrate, where a portion of the dopant well is between the substrate and a portion of the isolation well. In another embodiment, a contact is further disposed within the epitaxial layer, where a portion of the isolation region surrounds a portion of the contact. |
