Abstract: PROBLEM TO BE SOLVED: To prevent destruction phenomenon in a manufacturing process and improve anti-corrosion and characteristic against stress corrosion cracking, by forming an LOC-type lead frame of copper alloy of IACS having conductivity in a specified range. SOLUTION: An LOC-type lead frame 11, wherein a lead 12 extends on an element 10, is formed of copper alloy of IACS of 5-25%. The copper alloy contains Zn as first alloy component and one element selected out of a group of Sn, Si, Ni as second alloy component. As a result, a thermal expansion coefficient approximates that of the element 10 and a sealing resin 16, and an LOC package wherein destruction phenomenon is hardly generated and high in reliability is obtained. By covering Pd and Ru, reliability is more improved. Material cost is reduced more than in a conventional case, and mounting efficiency required by enlargement of an element which is to be caused by high level integration of a semiconductor device can be improved.

Abstract: PURPOSE:To avoid machining damage and to allow the steepness of the longitudinal interface to be controlled at a monoatomic order by a method wherein a trapezoidal super-lattice is grown on a substrata which is machined into a specified shape, and the trapezoidal super-lattice is embedded by the continuous growth. CONSTITUTION:A long stripe-shaped etching mask 5 is arranged on the face (001) of a GaAs substrate in the direction [110] to make a stripe with steps on the substrate 1 in the direction [110] by etching. AlAs 8 is grown on the substrate by an organic metal vapor phase growth method. At this time, the growth conditions are adjusted so that the layer grows into a trapezoid shape on the upper surface of the trapezoid and the width of the upper surface will be less than 100 nanometer. Then, GaAs 3 and AlAs 2 are grown in order. At this time, they do not grow on the side wall of the trapezoid so that, in the case of a trapezoid-shaped or triangular super-lattice-trapezoid-shaped super- lattice, after AlAs is grown on it to be a triangular shape or in the case of triangular super-lattice, the trapezoid-shaped or triangular super-lattice is covered with the growth of AlAs 4. Thus, a quantum thin line is present in the section of GaAs 3 enclosed in the dotted line.
