摘要：PURPOSE:To increa the reliability of a miconductor element by a method wherein supersonic waves are applied to the blade which comes in contact with the miconductor single crystal wafer and the cleavage of the wafer, having small crystal distortion, is formed at a plurality of spots simultaneously. CONSTITUTION:The blade 2 of a knife is brought into contact with the circumferential ction of a (100) GaAs single crystal wafer 1 and, at the same time, the supersonic waves generated by the supersonic waves generator 3 are applied to the above. A cleavage is easily formed without having a distortion on the crystal. Accordingly, the cleavages having no distortion on the crystal can be formed at two spots or more simultaneously.
