Patent ID: 7030952

Claim:
A microdisplay pixel cell device, the device comprising: a semiconductor substrate defined with a plurality of active areas; two gates, each of the gates covering a portion of the active areas; four sources and two drains, the sources and the drains being in the active areas not covered by the gates; a first dielectric layer, the first dielectric layer covering the two gates, the four sources and the four drains, the first dielectric layer comprising at least one row select contact plug to electrically connect to the one of the gates; at least one row select line, the row select line being atop the first dielectric layer, the row select line being electrically connected to one of the gates through the row select contact plug; a second dielectric layer, the second dielectric layer being atop the first dielectric layer and covering the row select line; four pixel cap top plates, each of the pixel cap top plates being atop the second dielectric layer and partially covering one of the active areas and one of the gates, and being electrically connected to one of the sources; at least one first contact plug, the first contact plug being in the first dielectric layer and the second dielectric layer for electrically connecting one of the sources and one of the top plates; at least one capacitor dielectric layer, the capacitor dielectric layer being atop the surfaces of the top plates; and one pixel cap bottom plate, the pixel cap bottom plate being atop the second dielectric layer and covering all of the two gates, the four sources, the two drains, the four top plates and the capacitor dielectric layer.
