CPC G01B 11/272 (2013.01) [H01L 29/66143 (2013.01); H01L 29/872 (2013.01)] | 16 Claims |
1. A self-aligned light angle sensor which forgoes the need for calibration comprising:
a substrate;
a cathode disposed on the substrate;
an intrinsic layer disposed on the cathode;
left and right anodes, each of which is disposed on the intrinsic layer and configured to sense light therein, wherein the left and right anodes comprise a metal;
a blocking member disposed proximally to the left and right anodes; and
a passivation layer between the blocking member and each of the left and right anodes.
|
9. A light angle sensor comprising:
a cathode;
an intrinsic layer disposed on the cathode;
left and right anodes, each of which is disposed on the intrinsic layer and configured to sense light therein;
a blocking member disposed proximally to the left and right anodes; and
a passivation layer between the blocking member and each of the left and right anodes,
wherein the left and right anodes comprise a metal silicide.
|
13. A light angle sensor comprising:
a cathode;
an intrinsic layer disposed on the cathode;
left and right anodes, each of which is disposed on the intrinsic layer and configured to sense light therein, wherein the left and right anodes comprise a metal silicide;
a first blocking member disposed proximally to the left anode;
a second blocking member disposed proximally to the right anode, the second blocking member spaced apart from the first blocking member; and
a passivation layer between the first blocking member and the left anode and between the second blocking member and the right anode.
