Abstract

1,057,127. Removing metal by laser or electron beams. UNITED AIRCRAFT CORPORATION. Oct. 17, 1963 [Oct. 31, 1962], No. 40956/63. Heading B3V. [Also in Divisions B5 and H1] A slab of material which when scribed or indented, fractures under load in a brittle fashion is subdivided by scribing with a high energy beam, e.g. a laser or electron beam and then fracturing in accordance with the pattern of scribing. The material may be a semiconductor containing a multiplicity of devices, e.g. of silicon, germanium, gallium arsenide, indium antimonide, aluminium phosphide or silicon carbide, a metal such as tungsten or molybdenum, or ceramics such as alumina, beryllia, and cermets. In the embodiment the scribing is effected in vacuo by an electron beam in the apparatus shown in Fig. 1. This comprises a direct heated cathode 20, an apertured grounded anode 22, focusing coils 28, 30 and a magnetic lens 32. A pattern of intersecting lines is scribed by scanning using deflector coils 34 controlled by an operator with the aid of the perta-mirror assembly shown. Alternatively deflection and pulsing of the beam are automatically controlled in accordance with a programme. The slab is subsequently broken up by ultrasonic vibration in a tank containing water or acetone, or by passing it between rubber balls to distort it. If desired electrodes may be welded to the semi-conductor slab by the beam before subdivision.
