Pre-multiplexed detector array

A detector array for sensing electromagnetic radiation, comprising:

• a semiconducting layer of a first conductivity type;
• an array of junction regions of a second conductivity type in a major surface of said semiconducting layer;
• a first insulating layer disposed over said major surface;
• a plurality of conducting plates disposed on said first insulating layer around each junction region for creating, upon the application of an electrical potential between each plate and said semiconducting layer, an induced junction region in said semiconducting layer and adjoining said junction region;
• a second insulating layer disposed over said conducting plates and said first insulating layer;
• a contact through said first and second insulating layers associated with each junction region;
• a plurality of control lines disposed over said second insulating layer, each conducting plate being connected to a control line for selectively applying said electrical potential to said plate;
• a third insulating layer over said control lines, said contacts, and said second insulating layer;
• and
• an opening through said third insulating layer over each of said contacts.
