Abstract (en)
[origin: DE4310640C1] The mfg. system for a Si:H thin-film transistors with storage capacitors uses 2 sputtered and structured chrome surfaces (11,12) applied to a substrate (10), respectively providing a row line nad a gate contact for each thin film transistor (19) and the base electrode of the storage capacitor. A gate isolator (13) and a Si:H intrinsic and doped semiconductor layers (14,15) are then applied, with wet or dry etching of the semiconductor layers via a metallisation mask. An indium-tin oxide is deposited and structured to form image print electrodes with a further metallisation for the matrix columns and etching of the metallisation mask using the indium-tin oxide as the mask. A transparent passivation layer is then applied. USE - For simplified mfr. of liquid crystal display screen.
