摘要:
A base film is formed for the TFTs in order to prevent diffusion of impurities from the glass substrate into the active layer, to maintain stability in the characteristics such as Vth and S-value of the TFTs and to maintain enhanced productivity. A film in which the composition ratios of N, O and H are continuously changed by changing the flow rates of H2 and N2O, is used as the base film to prevent a change in the TFT characteristics. The base film can be formed by varying the flow rates of H2 and N2O in the same film-forming chamber to enhance the productivity.

An object of the present invention is to prevent the deterioration of a TFT (thin film transistor). The deterioration of the TFT by a BT test is prevented by forming a silicon oxide nitride film between the semiconductor layer of the TFT and a substrate, wherein the silicon oxide nitride film ranges from 0.3 to 1.6 in a ratio of the concentration of N to the concentration of Si.

A tape cartridge housing a magnetic tape includes an auxiliary storage medium having a storage unit in which to store the recording medium information such as design parameters or the number of times of recording and/or reproduction of the magnetic tape, and a transmission/reception unit for effecting inputting/outputting of the recording medium information with the recording and/or reproducing apparatus. The auxiliary storage medium is mounted so that the transmission/reception unit is exposed to the outside through an opening provided in a lateral surface of the main cartridge body unit not obstructing the loading of the magnetic tape, that is in a surface of the main cartridge body unit other than its front surface as an inserting end of the tape cartridge into the inside of the recording and/or reproducing apparatus. The auxiliary storage medium has an antenna constituting the transmission/reception unit for inputting/outputting the recording medium information with the recording and/or reproducing apparatus. It is through this antenna that the power is supplied from the auxiliary recording and/or reproducing unit provided on the recording and/or reproducing apparatus in accordance with a non-contact system transmitting the recording medium information and the power overlaid on the recording medium information.

摘要:
When an amorphous silicon film is formed by a plasma CVD method, a hydrogen gas is supplied into a chamber before the start of film formation to cause discharge. In this state, film formation is not made. At the step where the discharge becomes stable, silane as a film forming gas is supplied into the chamber. At the same time, supply of the hydrogen gas is stopped. Silane is decomposed by the stable discharge, and film formation of an amorphous silicon film is made. By doing so, it is possible to eliminate the instability at the start of discharge. Film formation can be carried out in the state where the discharge is always stable. Also, in the plasma CVD method using silane as the film forming gas, supply of the silane gas is stopped in the state where the radio frequency discharge is maintained, and instead of the silane gas, the hydrogen gas as the discharge gas is supplied. For a predetermined period of time, plasma without film formation by decomposition of the hydrogen gas is formed. Since a negative self bias is applied to the formed surface in this state, negatively charged minute particles do not adhere to the formed surface. The discharge is stopped in the state where the minute particles in the atmosphere are exhausted. In this way, the state where the minute particles do not adhere to the formed surface can be made.
