Title: Manufacture of thin-film transistor
Inventor: JUMONJI SHIN
IPC: H01L21/302
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a thin-film transistor, by which the performance and manufacturing yield of a thin-film transistor can be improved by wet-etching the upper layer parts of source and drain electrodes and collectively dry-etching the other layers. SOLUTION: After a titanium layer 6 and an aluminum layer 7 are formed into a two-layer structure for source and drain electrodes and the aluminum layer 7 is wet-etched, the parts of the titanium layer 6, a low-resistance layer 5, and channel layer 4 are collectively removed by dry etching. Since the number of layers to be dry-etched can be reduced, uniformity of etching is improved, and in particular, the low-resistance layer 5 can be maintained easily in a prescribed film thickness. Accordingly, the characteristics of a thin-film transistor can be improved. Since the aluminum layer 7 is wet-etched, additionally the occurrence of defective etching due to dust, which works as a mask can be prevented and the manufacturing yield of the thin film transistor, can be improved.

A polyimide resin film 4 is attached onto a defective emitter section 11 detected. The film has inferior adhesion with an aluminum electrode metal applied onto an silicon surface in a subsequent process, and also resists a high temperature at a time when the electrode metal is affixed through evaporation, etc, and subsequent chemical treatment. The patterns of cathode electrodes 5 and gate electrodes 6 are shaped through a photoetching process. An Al electrode on the film 4 can easily be peeled through treatment called sintering. The film 4 on the defective emitter section 11 can be left as an insulating protective film as it is, thus improving the reliability of an element.
