Filed: 1988-07-11
Abstract: PURPOSE:To obtain a highly functional and a small mounting width hybrid integrated circuit by exposing part of other main surface of a printed board out of a resin seal portion and providing an electrode for external connection via a through hole. CONSTITUTION:There are provided on a main surface of a printed board 2 having through holes 4 a passive element chip 5 and an active element chip 8, and a resin sealing portion 3 for sealing these chips 5 and 8 and a metal wiring connecting these chips. In this hybrid integrated circuit, bumps 1 are provided on the rear surface side ends of three through holes 4 in the board 2 in place of a lead frame for external connection, and the resin sealing portion 3 seals the upper and the side surfaces of the board 2, and the bottom part thereof exposes the bumps 1. A solder resist layer 9 is formed on the rear surface of the board 2 except the region of bumps 1 and this board can be mounted directly to an external board. In this case, the mounting width can be made smaller, because the width l of the hybrid integrated circuit, the mounting width, is smaller than the conventional mounting width.

Title: Driving method of magnetic bubble memory element
Inventor: AMATSU MASASHI
IPC: G11C11/14
Filed: 1982-10-04
Abstract: PURPOSE:To hold down the increment of the power consumption, by superposing a relatively low auxiliary driving current to a normal driving current for a short time. CONSTITUTION:A square voltage pulse 10 corresponding to HD1 is supplied to an X coil, and a square voltage pulse 11 corresponding to HD1 is supplied to a Y coil, and further, an auxiliary driving voltage pulse 12 is applied to the Y coil near a phase of 0 deg. where a bubble traverses the gap of a half disc transfer path. Therefore, the Lissagjou's waveform of the driving magnetic field is expanded near 0 deg., and the amplitude and the pulse width of this auxiliary driving voltage pulse are selected properly to compensate sufficiently the rise of the driving magnetic field in the gap part of the transfer path, thus holding down the increment of the power consumption.

Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a technique to raise the reliability of a semiconductor integrated circuit device having wirings formed by a damascene process. SOLUTION: An Si nitride film 3b is an etching stopper film in forming on a TEOS film 6a a trench pattern 7 into which a second layer wiring M2 is buried, but the trench pattern 7 is not formed on the Si nitride film 3b, hence there is no need of applying an excessive over-etching to the Si nitride film 3b and no undercut appears at the Si nitride film 3b. Accordingly, a TiN film 8a is deposited at an approximately uniform thickness on the inner walls of the trench pattern to thereby avoid diffusing Cu from a Cu film 9 to the layer insulation films 2, 3, 6 or semiconductor substrate 1.

Filed: 1989-07-07
Abstract: PURPOSE:To extent the time up to when the density of inflammable gas in the containment reaches a limit value by coupling the vapor phase parts of a dry well and a suppression chamber outside them by piping through a blower and a valve. CONSTITUTION:If a cooling material loss accident occurs, valves 13A and 13B are opened and the blower 11 is actuated to send the air in the dry well 2 to the space part 3a of the suppression chamber 3 through suction piping 12. As the gas is sent to the chamber 3, the pressure in the chamber 3 rises gradually by the pressure of the dry well 2 and when preset pressure is reached, a vacuum breaking device 5 is opened to return the gas in the chamber 3 to the dry well 2. Thus, a flow of the gas from the dry wall 2 is generated through the blower 11, chamber 3, vacuum breaking device 5, and then dry well 2. Consequently, the gas in the dry well 2 and the gas in the chamber 3 are mixed. Consequently, the time up to when the density of the inflammable gas in the containment reaches the limit value can be extended.
