Abstract
A line scanner compries a conductive film which has been patterned to define a plurality of electrodes, each with an attached lead, is covered with a layer of photosensitive a-silicon and the silicon in turn is covered with an insulating resin. The insulating film is patterned to open a linear window which exposes equal amounts of each electrode and attached lead and a common electrode overlies the resin and contacts the electrodes and leads through the window.
Claims4
A linear scanner comprising:
- an insulating substrate;
- a plurality of individual electrodes, each spaced apart in a linear row, disposed on the insulating substrate;
- a plurality of leads, attached to respective ones of the individual electrodes;
- a plurality of wires connected to respective ones of the plurality of leads;
- a layer of photosensitive semiconductive material overlaying the plurality of individual electrodes;
- an insulating film overlying the layer of photosensitive semiconductive material and the individual electrodes, said insulating film having a linear window which is positioned to expose essentially only a region of the photosensitive semiconductive material layer directly overlying the plurality of individual electrodes, and being substantially coextensive therewith;
- and
- a common electrode layer overlying the insulating film, overlapping the linear window therein and contacting the layer of photosensitive semiconductive material through the linear window.
