Title: Wiring forming method
Inventor: OKAJIMA TAKEHIKO
IPC: H01L21/768
Filed: 1993-06-14
Abstract: PURPOSE:To prevent occurrence of a connecting malfunction in a contact hole having a large aspect ratio when multilayer wirings are formed by electrolytic plating. CONSTITUTION:A current film 42 is deposited on an insulating film 40 having a contact hole 40a by sputtering or depositing. When an aspect ratio of the hole 40a is large, a cutting seam 46 of the hole 40a is generated at a bottom of the hole. Then, a resist 44 having a window 44a for exposing a wiring forming region is formed on the film 42. Then other current film 48 is deposited on the film 42 of a wiring forming region by electrolessly plating. According to the electroless plating, the film 48 can be also grown on the film 40 to be exposed from the seam 46. Accordingly, since the entire region can be covered with the films 42, 48, the films can be formed as the electrodes by electrolytic plating.

Title: Degassing apparatus
Inventor: MORIKAWA HIDEYUKI
IPC: B01D19/00
Filed: 1995-06-09
Abstract: PURPOSE: To obtain a small-sized and inexpensive degassing apparatus generating no mutual interference by providing a check valve opened when the pressure in a vacuum chamber is higher than that of a pressure adjusting chamber to the pipeline connecting both chambers. CONSTITUTION: When a liquid is passed through the permeable membrane tubes 3, 4 of vacuum chambers 1, 2, the gas contained in the liquid transmits through the wall surfaces of the permeable membrane tubes 3, 4 to be degassed and removed into the vacuum chambers 1, 2. When the pressures in the vacuum chambers 1, 2 are higher than that of a pressure adjusting chamber 7, check valves 8, 9 are opened to extract the pressures in the vacuum chambers 1, 2 toward the pressure adjusting chamber 7. The gas removed from the liquid is discharged to the atmosphere through a vacuum pump 10. Since only the valve connected to the vacuum chamber of which the pressure is higher than the pressure adjusting chamber 7 among the check valves 8, 9 are opened, the gas in the vacuum chamber high in pressure flows in the vacuum chamber low in pressure, mutual interference is not generated.
