Title: Electronical light axis adjusting device for scanning type electron microscope
Inventor: YAMADA OSAMU
IPC: H01J37/141
Filed: 1985-05-15
Abstract: PURPOSE:To obviate the need for field excitation re-adjusting when the same field excitation level is used again, by permitting the field excitation level of a convergent lens to be variable in plural steps and installing a deflection magnetic field generating means for adjusting an axis above an object lens, with its field excitation changeable in the number of plural steps. CONSTITUTION:A rotary switch 13 chanegable in 16 steps is a binary code switch with 4-bit output, which selects one of sixteen different voltages applied to sixteen input lines of an analog multiplexer 12 for driving a current amplifier 7 so as to excitate a convergent lens 2. The output of the rotary switch 13 is also used as switching inputs for multiplexers 14, 15 and demultiplexers 18, 19 respectively. This arrangement allows to obviate the need for axis re- adjusting when the previously used field excitation level is selected again, and makes operations of the electron microscope extremely easier.

Title: Semiconductor device isolation method
Inventor: NOGUCHI MASAHIRO
IPC: H01L21/306
Filed: 1987-04-24
Abstract: PURPOSE:To obtain a semiconductor device isolation method whose loss during the formation of a groove is small, whose yield is enhanced and where a damaged layer due to a stress does not remain by a method wherein, after the whole surface of a semiconductor epitaxial-wafer has been coated with an organic resin and the groove has been formed by a dicing operation from the surface of the epitaxial-wafer, a chemical etching operation is executed. CONSTITUTION:A coated film 6 of an etchant-resistant organic resin is formed on the whole surface of an epitaxial-wafer 1 where an electrode has been formed. Then, after the coated film 6 has been cut and removed by a dicing operation, the epitaxial-wafer 1 is cut and a groove which is deeper than a P-N junction face is formed. Then, about 1-5 mum of a damaged layer 4 where a stress has been caused due to the dicing operation are removed by an etching operation. In this case, if the wafer is composed of, e.g., GaAlAs, a phosphoric- acid-related etchant is to be used. Lastly, the film 6 which has coated the surface is removed and the formation of the groove is completed. By this setup, an area which is lost as a cutting margin is reduced; the damaged layer can be removed as compared with a process using only the dicing operation; the long life of a chip can be achieved.
