Title: Semiconductor device and its manufacture
Inventor: AYABE MASAYUKI
IPC: H01L29/73
Filed: 1993-12-27
Abstract: PURPOSE:To improve the Early voltage of a transistor by a method wherein P-type impurities are implanted into an N-type collector region directly under a base to make an N-type impurity concentration of the part directly under the base lower than the N-type impurity concentration of the other part. CONSTITUTION:B ions which are P-type impurities are implanted into the part of an N-type epitaxial layer which is to be a collector region and diffused by annealing to form a region 5 whose impurity concentration is lower than that of the N-type epitaxial layer 4 formed beforehand. Then P-type impurities are implanted into the part of the N-type epitaxial layer 4 surface corresponding to the lightly-doped region 5 to form a base region 6. Then N-type impurities are implanted into the base region 6 to form an N-type emitter region 7. With this construction, when a transistor is operated, a depletion layer spread between the base and collector is difficult to be spread in the base direction and an Early voltage is increased. With this constitution, a transistor for the compensation of the Early voltage in an integrated circuit can be eliminated, so that the chip size of the integrated circuit can be reduced.

Title: Packing body
Inventor: MOCHIZUKI AKIRA
IPC: B65D81/24
Filed: 1990-11-30
Abstract: PURPOSE:To prevent the generation of a pinhole in a packing container and breakage such as tearing and peeling by providing a gas impermeable closed packing container with a regulation means inside to regulate motion such as oscillation of a product housed. CONSTITUTION:A packing body 1 houses a container 11 which holds a substance liable to denaturalize by oxygen, for example, a transfusion agent containing amino acid. A regulation means of 'motion' comprising a recess 19 or the like which is formed in a shape corresponding to an outline of the product held to prevent the product held in the container 11 or the like from deviate in position as caused by vibration or oscillation during the conveying, transporting thereof or the like. The product held is kept from deviating or moving from a specified holding position even when the packing body is conveyed or transported and hence, will not impact the packing container. There is no generation of pinhole in the packing container and neither tearing nor peeling is possible. This allows the packing container to keep oxygen zero or low in level combined with an effect of an oxygen removing agent 17 held simultaneously thereby enabling the preservation of the product held stably for a long time.
