Samsung patents image sensor layout with extra shielding contacts
Samsung describes an image sensor design that adds a 'dummy' gate and a specific shielding contact alongside the standard wiring. These extra components are placed in parallel with the main connections to help manage electrical signals within the sensor's structure.
In the filing’s own words
An image sensor includes a substrate including a plurality of photoelectric conversion regions, a separation pattern between the plurality of photoelectric conversion regions and separating the substrate, a plurality of active patterns on the substrate, a plurality of gate patterns overlapping the plurality of active patterns, a connection contact connected to the plurality of active patterns or the gate pattern, a dummy gate pattern overlapping the separation pattern, and a shield contact connected to the dummy gate pattern, wherein the shield contact and the connection contact are in parallel in a first direction.
What exactly they claim (claim 1)
1. An image sensor comprising a substrate comprising a plurality of photoelectric conversion regions; a separation pattern between the plurality of photoelectric conversion regions and separating the substrate; a plurality of active patterns on the substrate; a plurality of gate patterns overlapping the plurality of active patterns; a connection contact connected to the plurality of active patterns or the plurality of gate patterns; a dummy gate pattern overlapping the separation pattern; and a shield contact connected to the dummy gate pattern, wherein the shield contact and the connection contact are in parallel in a first direction.
