Self-aligned light angle sensor using thin metal silicide anodes

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.

• 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.
