Patent JP-H09148321-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: SHIBATA KOJI
IPC: H01L23/522
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To provide an insulating layer free from separation or cracking by depositing a fluorine-free silicon oxide film on a fluorine-containing silicon oxide film and then a spin-on-glass film thereon. SOLUTION: A first fluorine-containing oxide film 12 is deposited on a first interconnection layer 3. A silicon oxide film 13 is deposited on the oxide film 12, and an SOG film 14 is formed thereon to obtain a flat surface. Since the silicon oxide film 13 between the first silicon oxide film 12 and the SOG film 14 is free from fluorine, the coating material for the SOG film 14 does not make direct contact with the surface of the first oxide film 12 containing Si-F. In addition, the adhesion between the silicon oxide film 13 and the SOG film 14 is improved and heat shrinkage is relatively small. Therefore, it is possible to provide a reliable insulating layer including an SOG film free from separation or cracking.

Filed: 1990-11-14
Abstract: PURPOSE:To improve productivity by mounting a core to a rewinding shaft, consisting of a carbon shaft, and rewinding a film so that a roll excellent in appearance with small roll-in air is obtained even when a rewinding speed is increased. CONSTITUTION:Constitution is provided such that a film is rewound by mounting a core to a rewinding shaft formed of a carbon shaft.
