IPC: C22C14/00
Filed: 1994-11-30
Abstract: PURPOSE: To produce a Ti alloy hot forged member having high strength and high rigidity by specifying the composition and structure of a Ti alloy containing Al, Mo, Zr, and Si. CONSTITUTION: This Ti alloy hot forged member has a composition consisting of, by weight, 7.5-11% Al, 0.5-3% Mo, 0.5-2% Zr, 0.01-0.5% Si, and the balance Ti and also has a structure in which equiaxial α-phases are distributed by 70-90area% in a matrix of β-phase. When Al content is below the lower limit, the proportion of the equiaxial α-phases to be formed becomes less than 70area% and the desired strength and rigidity cannot be secured and, on the other hand, the proportion of the equiaxial α-phases exceeds 90area% and toughness is deteriorated when it is above the upper limit. As to Mo content, when it is below the lower limit, hot forgeability cannot be secured, and rigidity is deteriorated when it exceeds the upper limit.  When Zr content is below the lower limit, a rigidity-improving effect cannot be obtained, and, when it exceeds the upper limit, strength is deteriorated. Further, when Si content is below the lower limit, a strength-improving effect cannot be obtained, and, on the other hand, hot forging crack is liable to occur when it exceeds the upper limit.

Title: Semiconductor device and its manufacture
Inventor: MORIHARA TOSHINORI
IPC: H01L21/02
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To suppress the concentration of electric field in the pn junction without eliminating merits of an LDD structure and also suppress effectively the hot carrier effect and leakage current. SOLUTION: An insulation film 9 works as a protection film for the main surface of a semiconductor substrate 100 when a side wall 10 is formed by anisotropic etching, so that the main surface is prevented from being damaged by etching. Therefore, the concentration of electric field in the pn junction part is relieved and the merits of an LDD structure are utilized effectively. A part of the insulation film 9 jutted outside from the side wall 10 is removed, so that it is unnecessary to be etched when forming a contact hole 12, and only an insulation film 11 can be etched selectively. Thus, a short circuit between a main electrode 13 and a gate electrode 7 can be prevented, and a distance between contact holes 12 can be set to be smaller than a width of the gate electrode 7.
