IPC: B05D3/10
Filed: 1988-10-31
Abstract: PURPOSE:To reduce the consumption of a solvent by carrying out the drying process after cleaning process in the state that a material to be cleaned is stopped for a given period of time in a position that the upper and lower ends of the material to be cleaned are not projected out of the upper and lower ends of a cooling coil. CONSTITUTION:A hanger 5 is lifted up after the completion of cleaning and stopped in a position where the center of a material 100 to be cleaned corresponds with the center of a cooling coil. The air temperature in the vicinity of the cooling coil 3 in a recovery chamber 13 is lower than the room temperature, and saturated vapor pressure of solvent vapor in the recovery chamber 13 is lower than the saturated vapor pressure of room temperature. As the material 100 to be cleaned is heated up by a solvent condensed in a cleaning chamber 12 and its temperature is higher than the room temperature, the solvent condensed on the surface is volatilized quickly and condensed on the surface of the cooling coil 3 and recovered thereon, or condensed in the air of the recovery chamber 13 and dropped downward. Thus, the lowering of cleaning efficiency is minimized and drying of the material to be cleaned can be carried out effectively.

Abstract: PROBLEM TO BE SOLVED: To prevent short-circuiting at an electrode and deterioration of printing quality by forming a sidewall portion of an opposite conductivity type semiconductor layer in an exposed portion of one conductivity type semiconductor layer into an inserted mesa structure to thereby cut off the electrode at the inserted mesa portion. SOLUTION: In island-structured semiconductors 2 and 3 comprised respectively of a semiconductor layer 2 one conductivity type and a a semiconductor layer 3 of opposite conductivity type arrayed on a substrate 1, one pair of opposed wall surfaces forms a regular mesa structure due to the relationship between the plane direction of the crystal and the etching, and the other pair of opposed wall surfaces form an inverted mesa structure. In this case, a side- wall portion W of the layer 3 in an exposed portion R of the layer 2 is formed into the inverted mesa structure. That is, when stepped etching is performed, the portion W of the layer 3 is formed into the inverted mesa structure by using such an etching solution as to allow GaAs to have the regular mesa structure and AlGaAs to have the inverted mesa structure in its <1-10> orientation.  As a result, a portion of an individual electrode 4 on the layer 3 and its portion on the layer 2 can be cut off.
