JAW-SYSTEM CLEAVAGE DEVICE

摘要

PURPOSE: To provide a device for cleaving a GaAs bar from a cell, which can be used in ultrahigh vacuum by using a jaw for propagating the cleavage on one end of a laser bar and using a jaw for supplying a bias force on the other end of the laser bar. CONSTITUTION: A jaw 37, being tightly fastened to a plate, supplies a main force component to be used for cleaving a bar 23 from a cell 1. A jaw 39 can slide in a hole and includes a weight 43 which is located on an uncleaved face. The function of the jaw 39 and weight 43 is to give downward force to the bar 23, when the cleavage 24 advances from one side of the cell 1 to the other side. The destruction of the bar in an early stage and the formation of can be prevented by this function of the jar 39 and the weight 43. Thus, a GaAs bar manufacturing device which does not come into contact with an important section of a top face of the cell can be obtained.
