US5492843A - Method of fabricating semiconductor device ...

Method of fabricating a semiconductor device. A glass substrate such as Corning 7059 is used as a substrate. A bottom film is formed. Then, the substrate is annealed above the strain point of the glass substrate. The substrate is then slowly cooled below the strain point. Thereafter, a silicon film is formed, and a TFT is formed. The aforementioned anneal and slow cooling reduce shrinkage of ...

In2O3 films deposited by spray pyrolysis as a material for ...

The correlation between technological modes of In2O3 film deposition by spray pyrolysis and gas response to ozone is discussed in this report. In2O3 films were deposited from InCl 3–water solution (Tpyr = 300–550 C). It is shown that grain size, porosity, and film stoichiometry are the main factors controlling gas sensing characteristics of In 2O3 films.
