Title: Preparation of semiconductor device
Inventor: SUZUKI HIROSHI
IPC: H01L21/607
Filed: 1990-06-11
Abstract: PURPOSE:To protect wire disconnection of a semiconductor device by bending and fixing the inner lead using level differences prepared in a heater block and lugs in a clamp block. CONSTITUTION:A lead frame to be installed on a heater block 1 is laid in a condition that an inner lead 8 thereof is in contact with an upper part 3a of a level difference 3 in the heater block 1 and that a tip 8a of the inner lead 8 is suspended aparting from a bottom 3b of the level difference 3. Now, when thrusting a tip 8a of the inner lead 8 downward by a lug 7 of a sheet clamper 6, the tip 8a bends in a space generated between the level difference 3 at the heater block 1 and the lug of the sheet clamper 6 and a reaction to be caused by the bending causes the lead to be fixed tight to the bottom 3b of level difference 3. The inner lead 8 thus fixed is treated by the supersonic wire bonding while being heated by the heater block 1. With this, the tip of the inner lead is sufficiently fixed without generating resonance by the supersonic wave, thereby being able to avoid the occurrence of wire disconnection during the execution of bonding.

Abstract: PURPOSE:To enable easier perpendicular magnetization and increase of a signal quantity by providing a magnetic films consisting of two-layered films consisting of PtMnSb and rare earth-transition metal alloy. CONSTITUTION:An SiN film 3, a PtMnSb film 4, a TbFeCo film 5, and an SiN film 6 are formed in this order on a resin film 2 having spiral grooves and spin coating with silicone rubber 7 is executed. The PtMnSb film 4 is formed by an electron ray vapor deposition method. The SiN film 3 and the TbFeCo film 5 are formed by using RF magnetron sputtering. The formation of said films is executed by depositing the PtMnSb film 4 and the TbFeCo film 5 in this order on a flat glass plate and projecting laser light to the films from the glass side in the direction perpendicular to the film plane. Since the magnetic film is made into the two-layered structure consisting of the PtMnSb film 4 and the TbFeCo film 5, thetaK can be taken about 2.5 times larger and C/N is improved by 8dB as compared to a magneto-optical disk. The thetaK is thereby increased and the recording and reproduction are executed without degrading the perpendicular magnetic anisotropy.
