Title: Pretreatment of substrate in selective cvd of tungsten
Inventor: IZUMI AKIRA
IPC: H01L21/28
Filed: 1989-11-18
Abstract: PURPOSE:To perform surely selective formation of a tungsten film only onto the desired part of a substrate by accommodating the substrate in an airtight vessel which is isolated from the outside air and then, heating its substrate by keeping the vessel at a reduced pressure. CONSTITUTION:H2O that is attached to the surface of a substrate is one of the causes for contamination which inhibits selectivity in a selective CVD process of tungsten and H2O is removed effectively through a cleaning process of the substrate by the use of alcohol. As the substrate is accommodated in an airtight vessel which is isolated from the outside air in a subsequent heating process for the substrate, the substrate is not contaminated newly by coming into contact with the air and especially, no moisture sticks to the substrate. Further, H2O, -OH group on the surface of the substrate among factors which inhibit selectivity in the selective CVD process of tungsten are removed by heating the substrate in the vessel that is kept at a reduced pressure. Tungsten film is thus formed selectively only onto the desired part of the substrate with certainty.

The system is made operable without the communication line from the host 2 and the receipt of the signal C, i.e., when a music installer 38 directly transfers music data to the terminal 1, a signal C, which is equivalent to the clear signal C, is also transferred together with the music data and the memory of the number of elapsed days and the number of played musics are erased accordingly. Then, the playing function is made restartable.
