Patent JP-H01176077-A (JP)
Title: Thin film forming device
Inventor: NARUKAWA SHIRO
IPC: G03G5/08
Filed: 1987-12-28
Abstract: PURPOSE:To prevent the generation of flakes and to easily clean the inside of a reaction chamber by specifically arranging an inlet pipe in the title film forming device wherein a voltage is impressed between electrodes and a raw gas is introduced from the above-mentioned inlet pipe between the electrodes and decomposed. CONSTITUTION:A support 53 used as an anode and a heater is arranged at the center of the reaction chamber consisting of a cylindrical cathode 1, an electrically conductive substrate 54 is fixed, the inside of the reaction chamber is evacuated, and a raw gas is introduced from the inlet pipe 2 provided between the electrodes 1 and 53. A voltage is impressed between the electrodes 1 and 53, and a thin film is formed on the surface of the substrate 54. In this device, eight inlet pipes 2, for example, are firmly attached to the inner wall surface of the electrode 1, and integrated with the electrode. When a-Si is formed, for example, an Si-H polymer is formed during the film formation and suspended in the reaction chamber, or the a-Si deposited on the surface of the inlet pipe 2 is released and flaked. However, since the inlet pipe 2 is firmly attached to the electrode 1 in the device, there are only a few places having a large curvature, hence the generation of flakes can be controlled, and the reaction chamber is also easily cleaned.
