IPC: H01L21/301
Filed: 1979-06-29
Abstract: PURPOSE:To stop the removal of a crushing layer by chemicals, etc. and improve characteristics by a method wherein grooves in extents that do not reach a p-n junction from the back of a wafer are formed and separated into pellets. CONSTITUTION:A p-n junction is made up to a GaP substrate 8, an n-layer is polished as a mirror surface, and p-type electrodes 3 and n-type electrodes 4 are formed. The n-type electrodes 4 can be made sure from a p-type layer of the surface under this condition. The back is cut in depth shallower than the p-n junction 2 while conforming to the cutting pitches of the electrodes 3 from the n-layer of the back. According to this method, a crushing layer 5 is not formed at the p-n junction 2 of pellets and the area of the p-n junction is not decreased. Consequently, optical output is improved as compared to conventional devices, voltage drop in the forward direction is also reduced, and the removal of the erushing layer by chemicals is not required, thus resulting in high reliability.

Abstract: PURPOSE: To eliminate a troublesome operation of a setting key and also to prevent occurrence of an erroneous setting by a system wherein a preset memory is provided and the value is transmitted to a subtraction counter through an existing key operation.  
     CONSTITUTION: An hour data set in a display memory DM with a setting means S is set to a subtraction counter SC by way of AND gate circuit A 3  by actuating a start/stop key SS. When the hour data is not stored in a preset memory PM, the status is detected with a zero detecting means ZD, a circuit A 2  is activated, therefore the hour data of the key SS can be set in the memory PM. Where the data is stored in the memory PM and a change is not required, a transmission to the memory PM is blocked by the circuit A 2 . Then, where a value of the memory PM is changed, the data can be changed by storing the hour data of the subtraction counter SC to the memory PM through erasing it with an erase key K. Then, after actuating the key K to set to the display memory DM, a data transmitting key IK is actuated so that the hour data of the memory PM will be stored in the sounding memory M by way of a circuit A 5 .
