Title: Lead frame and manufacture of resin sealed semiconductor device using it
Inventor: NANO MASANORI
IPC: H01L23/50
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent generation of resin bur in a land electrode by providing a step part between the forward end of a land lead part and the end connected with a frame by means of a semi-cut press part thereby preventing sealing resin from flowing into the gap between a sealing sheet and the bottom face of the land electrode. SOLUTION: When a pressing force is applied to the frame side at the land lead 4 of a lead frame, bottom face of the land electrode 19 at the land lead 4 is located lower than the bottom face on the other end side because of a step part provided by a semi-cut press part at the land lead 4. Consequently, the regions of a semiconductor element 15, a die pad part 1 and a metal thin wire 17 can be resin sealed 18 on the upper surface side of the lead frame under a state where the bottom face of the land electrode 19 is surely brought into tight contact with a sealing sheet. Consequently, the sealing resin 18 can be prevented from flowing between the sealing sheet and the land electrode 19 and the occurrence of bur from the land electrode 19 can be prevented.

Filed: 1991-05-21
Abstract: PURPOSE:To improve the yield of beta-acryloxypropionic acid useful as a monomer raw material for imparting toughness, weatherability, etc., to a polymer and to easily and economically obtain the compound in an easily separable state. CONSTITUTION:beta-Acryloxypropionic acid can be produced by contacting acrylic acid with an ion-exchange resin (preferably cationic ion-exchange resin) at 50-130 deg.C (preferably 70-110 deg.C). It is preferable to use a polymerization inhibitor in the case of performing the process at high temperature or in the presence of impurities to prevent the progress of the polymerization of the raw material and the product. The yield of beta-acryloxypropionic acid can be improved by this process, the produced beta-acryloxypropionic acid can easily be separated and purified from the reaction mixture by conventional operations such as distillation and extraction and the ion-exchange resin can be repeatedly used. Accordingly, the process is extremely economical and industrially advantageous.

Abstract: PURPOSE:To prevent the electrification on the surface of an insulator sample and to determine exactly the surface compsn. and chemical condition of the sample by sticking conductive materials to the periphery of the analyzing point on the surface of the insulator sample then subjecting said point to an auger electron spectrochemical analysis. CONSTITUTION:The conductive materials 3 are deposited by evaporation into a pattern shape to the periphery of the analyzing point 4 on the surface of the thin insulator film 2 disposed on a substrate 1. The part between the conductive material patterns 3 and the point 4 are scanned by an electron ray to form a conductive property-changed part 5 on the extreme surface of the sample 2 and to blacken said surface, so that the parts between the patterns 3 including the point 4 are bridged by the conductive layer 5. The sample is thereafter subjected to the auger electron spectrochemical analysis, then the surface charge electrified to the analyzing point escapes through the layer 5 to the patterns and therefore the measurement is executed without electrification at all. The chemical condition is exactly determined from the surface compsn. and auger peak shape of the insulator material which was heretofore unmeasurable at all.
