Techniques for successively fabricating liquid crystal cells at low cost, using two resinous substrates wound on their respective rolls. A color filter and an electrode pattern are formed by printing techniques. Furthermore, an orientation film is printed. These manufacturing steps are carried out successively by rotating various rolls.

Nickel is selectively held in contact with a particular region of an amorphous silicon film. Crystal growth parallel with a substrate is effected by performing a heat treatment. A thermal oxidation film is formed by performing a heat treatment in an oxidizing atmosphere containing a halogen element. During this step, the crystallinity is improved and the gettering of nickel elements proceeds. A thin-film transistor is formed so that the direction connecting source and drain regions coincides with the above crystal growth direction. As a result, a TFT having superior characteristics such as a mobility larger than 200 cm2/Vs and an S value smaller than 100 mV/dec. can be obtained.

There are provided a substrate of a semiconductor device and a fabrication method thereof which allow to suppress impurity from turning around from a glass or quartz substrate in fabrication steps of a TFT. An insulating film is deposited so as to surround the glass substrate by means of reduced pressure thermal CVD. It allows to suppress the impurity from infiltrating from the glass substrate to an active region of the TFT in the later process.

摘要:
In an annealing process in which laser light is irradiated to a semiconductor thin film, a refractive index of the semiconductor thin film after laser light irradiation is measured and conditions for the next laser light irradiation are adjusted based on the measured refractive index value. For example, laser light irradiation conditions are adjusted so that semiconductor thin films always have the same refractive index. As a result, the annealing can be performed under the same conditions at every laser light irradiation even if the laser light irradiation conditions vary unavoidably.

Method of fabricating TFTs starts with forming a nickel film selectively on a bottom layer which is formed on a substrate. An amorphous silicon film is formed on the nickel film and heated to crystallize it. The crystallized film is irradiated with infrared light to anneal it. Thus, a crystalline silicon film having excellent crystallinity is obtained. TFTs are built, using this crystalline silicon film.

Writing of a second field is started at a time point when writing of a first field has been completed, while information written in the first field is held. Writing of a first field of the next frame is started at a time point when the writing of the second field has been completed, while information written in the second field is held. This driving method can attain high vertical resolution.
摘要:
A thermistor layer made of platinum is formed on a thin diamond film. An amount of heat carried away from the diamond film by a fluid is detected as a change in the temperature of the thermistor layer. The rear side of the diamond film is kept in contact with the fluid to prevent the material of the thermistor from being corroded by the fluid. In another aspect of the invention, a heating element and a thermistor are formed on one surface of a thin diamond film. The other surface is kept in contact with a fluid. The diamond film is heated by the heating element in a quite short time of about 0.2 second. The resulting response characteristics of the diamond film are detected by the thermistor. The flow rate is calculated from the response characteristics.

There is disclosed a hybrid circuit in which a circuit formed by TFTs is integrated with an RF filter. The TFTs are fabricated on a quartz substrate. A ceramic filter forming the RF filter is fabricated on another substrate. Terminals extend through the quartz substrate. The TFTs are connected with the ceramic filter via the terminals. Thus, an RF module is constructed.
摘要:
A little amount of nickel is introduced into an amorphous silicon film formed on a glass substrate to crystallize the amorphous silicon film by heating. In this situation, nickel elements remain in a crystallized silicon film. An amorphous silicon film is formed on the surface of the crystallized silicon film and then subjected to a heat treatment. With this heat treatment, the nickel elements are diffused in the amorphous silicon film, thereby being capable of lowering the concentration of nickel in the crystallized silicon film.
