Title: Highly reliable ceramic csp board
Inventor: HIDAKA AKIHIRO
IPC: H05K3/34
Filed: 1997-08-18
Abstract: PROBLEM TO BE SOLVED: To lessen the burden on a user by previously coating the side to be mounted on a PC board with a filling resin material, thereby eliminating the step for filling the gap between a CSP board and the PC board with resin after the CSP board is mounted on the PC board. SOLUTION: A filling resin material is applied previously to the entire circumferential fringe on the surface of a board or only required parts thereof. A thermosetting resin, typically an epoxy based resin, being set at a temperature for evaporating the volatile components of solder at the time of solder reflow is employed as the resin material. Resin coating parts 3 having inside diameter of 1 mm are set at four corners on the surface of a board 1 in case of sample (a), and the resin material is applied by 1 mm wide on the circumference of the board 1 in case of sample (b). Since a step for filling with resin material after mounting a CSP board is not required and the resin is set during solder reflow step, fatigue fracture at a solder joint is eliminated after mounting.

Title: Manufacture of semiconductor memory circuit device
Inventor: SHIMIZU SHINJI
IPC: H01L21/8247
Filed: 1983-11-28
Abstract: PURPOSE:To obtain an MOS semiconductor element such as a memory circuit of high withstand voltage, etc. without performing a complicated process in addition, by forming the second gate of an MISFET of high withstand voltage at the same time with the second gate of an MISFET which constitutes a memory cell. CONSTITUTION:The second gate 9 of the MISFET of high withstand voltage is formed at the same time with the second gate of the MISFET which constitutes the memory cell. By such a constitution, the withstand voltage against a drain voltage increases to BVDS-BVDSO+VG2 owing to the voltage VG2 of the second gate 9. On the other hand, the voltage transmitted by the second gate MOS is alleviated because of no existence of a floating n<+> layer between the first gate 7 and the second gate 9, therefore the breakdown of the first gate 7 does not generate. When the voltage of the second gate 9 increases sufficiently, breakdown generates on the side of the first gate 7.
