Inventor: AMAKASU TOSHIYA
IPC: C22C21/10
Filed: 1988-05-18
Abstract: PURPOSE:To easily obtain an Al alloy material having excellent reflectance for a laser beam without the limitation by material purity by regulating Al alloy rapidly solidified powder having specific compsn. consisting of Mg, Zn and Al to an extrusion material or a forging material. CONSTITUTION:Al alloy rapidly solidified powder constituted of, by weight, 3-6% Mg, 0.25-4.5% Zn and the balance substantially Al is regulated to an extrusion material or a forging material. The cooling speed of the rapid solidification in the above Al alloy is preferably regulated to about >=10<2> deg.C/sec. At the time of extruding the rapidly solidified powder, an Al oxidation film on the surface of the powder is cut into pieces by shearing and is finely dispersed into a matrix to unify. The extrusion ratio is suitably regulated to about 5-20 and the extrusion temp. to about 260-510 deg.C. As for the above working, similar effect is shown by forging as well. In this way, the Al alloy material having an excellent reflectance of which Al oxide is finely dispersed into an Al alloy matrix in which Zn enters into solid solution in the state of supersaturation can be obtd.

Abstract: PURPOSE:To reduce a leak current by gettering internal defects and heavy metal, by constituting a buried impurity layer of a main high concentration buried layer containing defects and low concentration sub-buried layers sandwiching the main buried layer in the depth direction. CONSTITUTION:A buried impurity layer 20 on a P<-> type semiconductor substrate 1 is constituted of an N<-> type main buried layer 21 containing secondary defects 22 like dislocation, and N-type sub-buried layers 3a, 3b positioned on and under the main buried layer 21. On the main buried layer 21, an N-type collector region 10 is formed, on the upper surface of which a P<+> type base region 4 and an N<+> type emitter region 5 are formed to constitute a transistor 200. Heavy metal and fine defects introduced during the manufacturing process are eliminated by gettering of secondary defects 22. The main buried layer 21 is sandwiched from above and below by sub-buried layers 3a, 3b of low impurity concentration, and a depletion layer is blocked by the layers 3a, 3b, and does not reach the secondary defects 22. Thereby the leak current of the transistor 200 is prevented. Since the formation of the buried layer 20 is not accompanied by epitaxial growth, manufacturing excellent in controllability is enabled at a low cost in a short time.
