摘要： In manufacturing a thin-film transistor on a glass substrate, a first thin film consisting of an amorphous silicon thin film is formed on the glass substrate, and a second thin film is formed on the first thin film. Then, this second thin film is etched to form a mask pattern. A dopant ion is doped into the first thin film through the mask pattern to form a source region and a drain region. The process of forming the mask pattern and the process of forming the source and drain regions are carried out continuously without exposing the substrate to the atmosphere.

摘要： In patterning a silicon-containing thin film formed over an insulating substrate by means of vapor-phase chemical etching using a resist pattern formed on the thin film as a mask, a luminescence intensity A of wavelengths in a predetermined wavelength range and a luminescence intensity B at a specific wavelength are detected during the patterning. The luminescence intensity B is divided by the luminescence intensity A to produce a divide signal (B/A). The time of termination of the patterning is determined based on a change of the divide signal.

摘要： A gate electrode of a thin film transistor is composed by a three layer structure obtained by laminating a titanium nitride layer as an upper layer on an aluminum layer as a base layer and by laminating an unalloyed titanium layer as a lower layer under the base layer. An ion implantation is used as an ion doping into a source region and drain region as an active layer of the thin film transistor. The source region and the drain region are annealed at a low temperature of 350° C. to 450° C. to be activated. A chemical reaction between the base layer and the upper layer and between the base layer and the lower layer can be suppressed. The rise of the resistance value in the gate electrode can be suppressed. The resistance of the gate electrode can be reduced. The fluctuation of the threshold voltage of the thin film transistor can be suppressed.
