Abstract
An apparatus and method for cleaving GaAs laser bars from a cell utilizes a first jaw applied to one end of a laser bar to propagate a cleavage and a second jaw applied to an opposite end which provides a biasing force that assures separation of the bar from the cell along the same crystallographic plane. The apparatus may be used in an ultra-high vacuum environment and allows handling of the bars without contacting the vital areas of the top surfaces or facet faces. The apparatus precisely locates bars after cleavage so that they may be further processed.
Claims11
A method of cleaving a semiconductor bar from a cell, comprising:
- positioning a cell underneath a pair of jaws which are spaced apart to contact said cell in non-vital contact areas on a first side of said cell, a first of said pair of jaws being fixed and a second of said pair of jaws being slidable and biased by a weight;
- supporting a bar section to be cleaved from a cell at a position in line with said pair of jaws and spaced therefrom;
- placing said pair of jaws in contact with said non-vital contact areas on said cell;
- and
- pivoting a remainder section of said cell relative to said bar section of said cell when said jaws are in contact with said bar section.
An apparatus for cleaving a semiconductor bar from a cell, comprising:
- positioning means for positioning a cell underneath a pair of jaws, said pair of jaws being spaced apart to contact said cell in non-vital contact areas on a first side of said cell;
- supporting means for supporting a bar section to be cleaved from a cell positioned in line with said pair of jaws and spaced therefrom;
- placing means for placing said pair of jaws in contact with said non-vital contact areas, a first of said pair of jaws being fixed relative to said placing means, a second of said pair of jaws being movable relative to said placing means, said second of said pair of jaws being biased by a weight;
- and
- pivoting means for pivoting a remainder section of a cell relative to a bar section of said cell after said jaws are in contact with said bar section.
