Title: Lead frame and manufacture of resin-sealed semiconductor device using the same
Inventor: ADACHI OSAMU
IPC: H01L23/12
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a lead frame, in which an external terminal is arranged in a row at the bottom of a package, the surface of each external electrode is positively exposed, and generation of resin flash can be prevented, and to provide a manufacturing method of resin-sealed semiconductor device using the same, by constituting the semiconductor device using a frame which can be mounted on a substrate at its bottom side. SOLUTION: In a lead frame for an LGA(land grip array), the surface of land lead electrodes 16 in a land lead part 4, whose bottom is to be a land electrode is arranged lower than the land surface of a lead part 5 in advance by a semi-cutting part 24. By doing so, since the land electrodes 16 cuts into and is bonded on a sealing seat in resin-sealing, the sealing resin does not flow into the surfaces of the land electrodes 16. As a result, resin flash is prevented from occurring on the surfaces of the land electrodes 16 of the land lead parts 4.

Abstract: PROBLEM TO BE SOLVED: To make recordable and reproducible data information in a high density and at a high speed and also at a high SN ratio without necessitating difficult controls and to make realizable a low cost of a device. SOLUTION: At the time of recording, the light passed through a polarization rotating element 26 is cast on an optical recording medium 10 as a signal light 1 by making the light passed through a beam splitter 24 by opening a shutter 25 to be incident on the polarization rotating element 26 and by modulating the polarizing angle of the light passing through the polarization rotating element 26 in accordance with multilevel information. Simultaneously, the light reflected in the beam splitter 24 is cast on an area which is irradiated with the signal light 1 of the optical recording medium 10, as a reference light 2. Thus, the polarizing angle of the signal light 1 is recorded on the medium 10 as a hologram.  At the time of reprodiction, the same light as the reference light 2 at the time of recording is read out by interrupting the signal light 1 while closing the shutter 25 and it is irradiated on the medium 10 as a light. A read-out light 2 is diffracted by the hologram recorded in the medium 10 and the diffracted light 3 becomes a light in which the polarizing angle of the signal light 1 is preserved. The diffracted light 3 is made to be incident on a polarizing plate 52 and the intensity of the diffracted light 4 passed through the polarizing plate 52 is detected with a photodetector 53.
