Patent number: 5923050Abstract: An amorphous silicon thin-film transistor as a switching element for a thin-film transistor liquid crystal display, having improved characteristics by making better an ohmic contact layer and an active layer, and a method of fabricating the same are provided. A wide energy-band gap .mu.c-Si(:Cl) fabricated using a mixed gas including SiH.sub.2 Cl.sub.2 is used as the ohmic contact layer, so that yield and productivity can be improved. The active layer is formed of .mu.c-Si:H(:Cl) with low hydrogen content and high stability. Off-current during illumination is sharply decreased, to thereby remarkably reduce leakage current when illumination is performed by backlighting.Type: GrantFiled: January 24, 1996Date of Patent: July 13, 1999Assignee: Samsung Electronics Co., Ltd.Inventors: Jin Jang, Jae-seong Byun, Hong-bin Jeon
