摘要: PROBLEM TO BE SOLVED: To achieve a semiconductor device using a TFT structure with high reliability. SOLUTION: As an insulating film used for the TFT, for example, a gate insulating film, a protecting film, an under film, an interlayer insulating film, or the like, a silicon nitride oxide film (SiN X B Y O Z ) containing boron is formed by a sputtering method. As a result, the internal stress of this film typically becomes -5×10 10 to 5×10 10 dyn/cm 2 , preferably -10 10 to 10 10 dyn/cm 2 , and the film has high thermal conductivity, so that it becomes possible to prevent deterioration due to heat generation during an on-operation of the TFT.

摘要: A first gas including a silicon-containing compound is introduced into a vacuum chamber, to expose a semiconductor substrate placed in the chamber to the first gas atmosphere (silicon processing step). Then the pressure inside the vacuum chamber is reduced to a level lower than the pressure at the time of starting the silicon processing step (depressurizing step). Thereafter, a second gas including a nitrogen-containing compound is introduced into the vacuum chamber, and the semiconductor substrate is irradiated with the second gas plasma (nitrogen plasma step).

摘要: PROBLEM TO BE SOLVED: To provide doping which allows the concentration and uniformity of a deposited dopant to be controlled by blocking some of the available binding sites for a dopant precursor with a blocking reactant and allows the blocking reactant to be introduced prior to introduction of the dopant precursor in an ALD (atomic layer deposition) process or allows the blocking reactant and the dopant precursor to be introduced simultaneously. SOLUTION: A method for doping a substrate surface or an interface between two thin films by the ALD process is provided. The ALD process generally comprises steps of providing a substrate to a reaction space and depositing a dopant on the substrate in a single ALD cycle, in which the substrate is contacted with a first reactant that is a blocking reactant such that the blocking reactant adsorbs in a self-limiting manner on the surface of the substrate.

摘要: PROBLEM TO BE SOLVED: To provide a manufacturing method of an insulating film capable of securing reliability even if its film thickness is thin, as an insulating film used in a semiconductor integrated circuit, and to provide a high quality insulating film at a low substrate temperature on a substrate having an insulating surface enlargeable in area such as a glass, in particular. SOLUTION: A monosilane gas (SiH 4 ), nitrous oxide (N 2 O) and a rare gas are introduced into a chamber, and high density plasma is generated under a pressure of 10-30 Pa to form the insulating film on the substrate having an insulating surface such as a glass. After that, the supply of the monosilane gas is stopped, and the nitrous oxide (N 2 O) and the rare gas are introduced without exposing them to the atmosphere to apply plasma treatment onto the insulating film surface.
