Title: Semiconductor device
Inventor: TAKAYANAGI CHIKANARI
IPC: H01L23/48
Filed: 1988-12-13
Abstract: PURPOSE:To make it possible to conduct easily the handling of a semiconductor device, whose external lead-out conductor is provided with a ferrite core, by a method wherein the external lead-out conductor provided on a semiconductor element main body is encircled and at the same time, the device is provided with the ferrite core which is coupled with the element main body. CONSTITUTION:Parts molded doubly with a ferrite resin 2 are each formed at both ends on the side of an anode terminal 3 and the side of a cathode terminal 4 of a semiconductor device 1 molded with an epoxy resin. Accordingly, noise generated by a high frequency can be prevented by the resin 2. When noise is generated by the effect of the device 1 and an output wave carried with the noise is outputted, the noise is prevented by making the output wave pass through the resin 2 on the side of the terminal 4 of the device 1. The resin 2 is molded doubly on the ends of the device 1. Thereby, there is no need to mount a ferrite core to the terminal 3 or the terminal 4 of the device 1 at a user.

Filed: 1990-11-21
Abstract: PURPOSE:To suppress low an etching of a semiconductor substrate in a pretreatment, which is performed before a metal film is buried in a contact hole and at the time of formation of an extraction electrode, as well as to make high an exhaust velocity in a chamber subsequent to the pretreatment by a method wherein fluorine-containing gas is used as etching gas and hydrogen gas is added to the gas to perform a plasma etching. CONSTITUTION:In a pretreatment which is performed before a metal film is buried in a contact hole opened in an insulating film forming on a semiconductor substrate, fluorine-containing gas is used as etching gas and hydrogen gas is added to the gas to perform a plasma etching. Thereby, an etching rate of a silicon film in the case NF3 gas, for example, is used as the fluorine-containing gas is shown as shown by the diagram and when the hydrogen gas is added to the NF3 gas, an etching of the substrate can be suppressed low because the etching rate of the silicon film is reduced. Moreover, when the hydrogen gas is added to the NF3 gas, a reaction of NF3+H2 .+NF is generated and as F* gas is rapidly exhausted as HF gas without remaining in chamber, an exhaust velocity in the chamber subsequent to the pretreatment can be made high.

Filed: 1988-12-15
Abstract: PURPOSE:To prevent breakage even if an excessive tightening torque is applied by a tightening tool by joining a joint body and a tightening member by a slit ring by fitting a recessed part formed on the joint body and a projection installed onto the tightening member. CONSTITUTION:Though a tightening member 30 is applied with a tightening torque by the screwing of a cap nut 50, a projection 32 projectingly installed at a flange part 31 is fitted into a recessed part 12a formed on the tool engagement part 12 of a joint body 10 and formed integrally with the body 10, and the revolution of the tightening member 30 following the screwing-in of the nut 50 is prevented. Further, though when the nut 50 is screwed excessively, the force for separating the tightening member 30 from the body 10 is generated, the shift of the member 30 to the nut 50 side is prevented, since a slit ring 40 is interposed between the member 30 and the tool engagement part 12. Further, even if the tightening tool is engaged with the engagement part 12, and revolved, the direct application of the tightening torque onto the member 30 by the tightening tool is prevented.

Title: Semiconductor memory
Inventor: FUDEYASU YOSHIO
IPC: H01L27/10
Filed: 1990-11-20
Abstract: PURPOSE:To improve serial data writing speed and serial data reading speed by making a driving capacity of a first inversion means larger than that of the second inversion means. CONSTITUTION:When reading a serial data, a reading data applied to a node (b) from a sense amplifier 30 is stored temporarily with inverters 430 and 440 and then, transferred to a data line 130 from a node (a). On the other hand, when writing a serial data, a writing data applied to the node (b) from the data line 130 is stored temporarily with transistors 430 and 440 and then, transferred to the sense amplifier 30 from the node (b). At this point, as a driving capacity of a first inversion means is large, a potential of a data bus means changes quickly according to the potential of the node (b). By the contrary, in the writing of the data, the potential of the node (b) develops quickly according to the writing data signal without being affected by an output of the second inversion means. This achieves improvements both in serial data reading speed and in serial writing speed.
