Title: Forming method of metal wiring pattern
Inventor: KOUNO HIROMICHI
IPC: H01L21/3065
Filed: 1980-12-22
Abstract: PURPOSE:To form a fine metal wiring pattern with a high reliability by a method wherein by limitting a radiating power of plazma on a sheet below 200 watts, a selective lift-off process of a metal film is facilitated. CONSTITUTION:On a circuit formation for example of titanium and platinum wiring pattern, a silicon oxide film 2 and a silicon nitride film 3 are formed on a silicon substrate 1 and a photo resist 4 is attached on them. Next the photo resist 4 is irradiated by ultraviolet ray selectively through the photo mask, and subsequently the photo resist of the unexposed resion is dissolved by its exposing to an organic solvent, and pattern 41 is formed. Next the whole of the substrate is exposed approxiamtely during 10sec to plasma containing CF4 gas having a high frequency power of approximately 50 watt. By this treatment adhesion between the attached metal film and the photo resist is lowered, and lift off process is facilitated. Furthermore a metal film is attached on the surface of the substrate, and by lift-off of a metal film where the photo resist remains, a metal wiring pattern is completed.

IPC: G05D1/02
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To decide whether or not a subsequent profile travel is possible in advance even if a break of a wall surface is detected by measuring the shape of a forehand object when a profile detecting means detects a break of the object, and performing specific operation according to the shape. SOLUTION: While the autonomous travel vehicle is in process of a contact profile travel along the wall surface 50, a contact sensor fitted to the flank of the autonomous travel vehicle judges whether or not the break of the wall is detected, and carries on the contact profile travel along the wall surface 50 unless a break of the wall is detected. When the break of the wall is detected, the autonomous travel vehicle stops at the place. Then the contact sensor is used to perform control so that the autonomous travel vehicle and wall surface become parallel to each other. Then, the distance of the object in the travel direction of the autonomous travel vehicle is measured by optical distance measuring sensors 3a which are arranged radially.  Then an operation means determines that the autonomous travel vehicle travels forward as it is, changes its travel direction and travels, or stops according to the measurement result.
