Title: Manufacture of semiconductor device
Inventor: ANDO HIDEMI
IPC: H01L21/336
Filed: 1989-11-17
Abstract: PURPOSE:To introduce impurities to an extremely shallow region to selectively obtain a resistance value with good controllability by a method wherein introduction of impurities is performed by ions including dopant atoms and activation of the introduced impurities is done by laser radiation and thermal treatment following the laser radiation. CONSTITUTION:Introduction of impurities into a semiconductor film is done by ions including dopant atoms generated by direct current arc discharge, and then laser radiation or heat treatment following the laser radiation is done. For example, poly Si is deposited on a glass substrate 1 and patterned, and then an SiO2 film and poly Si are formed sequentially to be patterned to have a gate insulation film 13 and a gate electrode 14 of a TFT formed. Then an ion doping apparatus is used to introduce impurities. H2-diluted 1% PH3 is used as dopant gas, while phosphorus is introduced into a source and drain 12 and the gate electrode 14 at acceleration voltage of 1keV. Further after a laser shielding film 31 is formed on the gate electrode 14, laser beam 32 of XeCl2 eximer laser is radiated to activate only the impurities in the source drain 12.

SOLUTION: A divided die 4 not radically expanded is inserted into a can 1. A plunger 6 is pushed up, and an expanding die 2 is radically expanded in the direction orthogonal to the axis via a taper surface 5. Each divided die 4 of the die 2 is moved outward in the radial direction of the can 1. Respective gaps 17 are generated between divided dies 4, the outer peripheral surface of the die 2 is simultaneously brought into contact with the inner surface of the can 1 and whereby the can 1 is expanded. A die 3 provided in the outer part of the can 1 is transferred while pressing it to the can 1, the can 1 is rotated in accordance with this, and the can is pushed in and formed with the die 3 matching the pitch of gaps 17.  Since pushing is applied to the part not being acted by the pressing force at the time of expanding, a severe forming is not applied, and then cracks or the like are not generated on the body surface 7 of the can.

Filed: 1991-10-17
Abstract: PURPOSE:To provide the ADPCM encoder not susceptible to the effect of noise by inputting digital data to a frequency conversion section and not implementing D/A and A/D conversion in the transmission process of data conversion section. CONSTITUTION:A digital signal processor (DSP) 30a of a frequency conversion section 14 reads the content of a memory 28a of an interface section 20 to apply sampling frequency conversion to digital data recorded in PCM at a prescribed frequency. Then the PCM audio data subject to frequency conversion are stored once in a memory 28b. A DSP 30b of a data conversion section 16 reads the content of the memory 28b and generates intermediate data resulting from converting part of the PCM audio data into ADPCM audio data. Then the data are once stored in a memory 28c and the DSP 30c reads the intermediate data stored in the memory 28c to generate complete ADPCM audio data and they are once stored in memories 28d, 28e. As a result, the effect of noise is immune to the encoder.
