    摘要: The invention involves technology related to chemical mechanical polishing using a chemical mechanical polishing apparatus having a wafer carrier for holding a semiconductor wafer, a polishing platen which is able to be rotated and which is positioned facing the surface of the wafer carrier on which the wafer is held, and a circular polishing cloth mounted on the polishing platen for polishing the semiconductor wafer, the polishing cloth having a smaller diameter than the diameter of the semiconductor wafer, and the polishing platen being movable horizontally across the surface of the semiconductor wafer. While rotating the semiconductor wafer held on the wafer carrier, the polishing platen is moved horizontally across the surface of the semiconductor wafer so that the displacement velocity of the polishing platen is slower at a central portion of the semiconductor wafer than at an outer portion, and the surface of the semiconductor wafer is polished with the polishing cloth. As a result, polishing uniformity is improved.

    摘要: A semiconductor device of this invention includes a semiconductor chip on which a device is formed, inner leads reaching the periphery of the semiconductor chip, and bonding wires for electrically connecting the semiconductor chip and the inner leads. The semiconductor chip is fixed on a die pad portion, and a chip fixing inner lead is integrated with the die pad portion. To simplify the bonding wire connection process and improve the reliability, the chip fixing inner lead has a step portion so that the die pad portion is formed at a lower position than the inner leads. The step portion is formed so as to be offset from a line of the end portions of the inner leads in the opposite direction of the semiconductor chip, so an arbitrary bonding wire can be kept apart from the step portion. According to this invention, a semiconductor device which can properly prevent contact between the step portion and the bonding wire to improve the reliability, and a lead frame applicable to this semiconductor device can be provided.

    摘要: In a semiconductor device having a resin-encapsulated structure, the width of an upper-mold portion of a package in a direction parallel to inner leads is made smaller than that of a lower-mold portion of the package so that the upper-mold portion cannot extend further towards outer leads than the lower-mold portion. Therefore, the amount of the positional deviation between an actual package region and a prospective package region is small and tiebars can be arranged close to the prospective package region in a lead frame. Since a fixed distance is ensured between the tiebars and the actual package region after molding, damage to the package is prevented during tiebar cutting. Since the amount of extension of any resin burr is small, a deflashing step is omitted.

    摘要: A gate electrode comprises a conductive gate electrode body and gate side walls. The channel region beneath the gate electrode has an NUDC structure having a p.sup.- impurity region and p.sup.+ impurity regions. The p.sup.- impurity region is formed before the gate electrode body. After the formation of the gate electrode body, the p.sup.+ impurity regions are formed by ion implantation before the gate side walls. The ion implantation is carried out perpendicular to the substrate so that the implanted ions will not reach further around the center of the channel region. Of the gate oxide films over the channel region, the thickness of the gate oxide films at both ends of the channel region is thinner than that of the gate oxide film in the middle of the channel length so as to suppress lowering of the current drivability.

    摘要: A latch-up protector, and an associated method, for an electronic circuit powered by both a fixed power supply and a pumped power supply. Operation of the latch-up protector prevents the occurrence of latch-up of the circuit during powering-up of the circuit. During powering-up of the electronic circuit, the latch-up protector prevents the application of an input signal to the electronic circuit which might instigate the occurrence of latch-up until the pumped power supply reaches a selected voltage level.

    摘要: A wafer cassette conveying system is capable of reducing a communication amount between a conveying device and a control device, further shortening the time period required for a movement of the conveying device. A control device 15, when receiving both of a lot carrying-in request signal outputted from a first treating device 11 and an empty cassette carrying-out request signal outputted from a second treating device 12, outputs a lot carrying-in command signal. A conveying device 20, when receiving this lot carrying-in command signal, conveys an actual cassette of the first treating device 11 to the second treating device 12 and also conveys an empty cassette of the second treating device 12 to an empty cassette space 14.

    摘要: A configurable input device for an integrated circuit having a plurality of input pads, the input device including a plurality of buffers, where each buffer is associated with one of the input pads. Each buffer receives a mode select signal and the buffer is responsive to the mode select signal to place the buffer in an enabled mode or a disabled mode. A receiver portion within each buffer is coupled to the associated input pad. The receiver portion pulls the associated input pad to a preselected logic state while the buffer is in the disabled mode. An output driver within each buffer generates an output signal responsive to a signal on the associated input pad while the buffer is in the enable mode and provides a high impedance while the buffer is in the disabled mode. An output node is coupled to the output drivers of the plurality of buffers.

    摘要: A p-type high concentration doped region is formed in a p-type semiconductor substrate between a n-type doped region as part of an input protection circuit and another n-type doped region as part of internal circuitry. A plate is divided into two over the high concentration doped region. The high concentration doped region suppresses generation of a parasitic MOS transistor with the plate for a gate, one of the n-type doped regions for a source, and the other for a drain.

    摘要: A mask ROM with increased memory capacity is disclosed. Besides MOS transistors each comprising a memory cell, MOS field shield transistors for device isolation, originally provided for electrically isolating the memory cell transistors, are also used as additional memory cells in addition to providing their isolating function. To write data in one of the field shield transistor, the threshold voltage of the field shield transistor is lowered, compared to field shield transistors in other regions. This is done by ion implantation of an n-type impurity into a p-type silicon substrate in a region beneath a gate electrode of the field shield transistor (a channel region). Data is read by judging on/off of the transistors when an intermediate voltage, between a high threshold voltage and a low threshold voltage is applied to a field shield line.
