Inventor: SACHITANO JACK
IPC: H01L21/336
Filed: 1988-04-15
Abstract: An intermediate structure in the fabrication of a metal-oxide semiconductor field-effect tran­sistor is made from a substrate of p+ silicon having an elongate insulated gate structure on its main face. First and second areas of the main face are exposed along first and second opposite sides respectively of the gate structure. Donor impurity atoms are introduced into the substrate by way of at least the first area of the main face, to a­chieve a predetermined concentration of electrons in a region of the substrate that is subjacent the first area of the main face. The gate structure is opaque to the impurity atoms. A sidewall of sili­con dioxide is formed along the first side of the gate structure, whereby a strip of the first area of the main face is covered by the sidewall and other parts of the first area remain exposed ad­jacent the sidewall. Donor impurity atoms to which the gate structure and the sidewall are opaque are introduced into the substrate by way of the portion of the first area that is exposed adjacent the sidewall. A layer of polysilicon is deposited over the portion of the first area of the main face that is exposed adjacent the sidewall. This layer ex­tends up the sidewall and over the gate structure. A layer of a polymer material is formed over the layer of polysilicon to a substantially uniform height over the main face. The height of the free surface of the layer of polymer material is at least as great as the maximum height of the layer of polysilicon over the gate structure. The poly­silicon at a height that is at least as great as that of the gate structure is then removed.

Abstract: The sensor contains a gas analysis electrochemical cell mounted directly on a slice of substrate (Sb). The whole slice is covered with enamel layers (S1, S2) except for sites required for electrical connections. A securing component (MF) holds the sensor inside a housing in such a way that the electrochemical cell is inside the housing in which the gas to be analysed is located. The securing component (MF) is gas-tight and prevents the gases from reaching the electrical connections. Application especially to oxygen sensors. <IMAGE>

Abstract: The manufacture of a casing, for example, for a piezoresistive pressure sensor in which a silicon chip provided with a pressure-sensitive membrane is inserted and cemented by hand into a prepared casing in the form of a metal sleeve composed of stainless steel has hitherto been extremely time-consuming and therefore associated with relatively high costs. In order to reduce the production cost for sensor casings, in particular for catheter tips of piezoresistive miniature catheters used as sensor housings, in the process according to the invention the sensor housing is manufactured by means of an injection moulding process using low-price injection moulding compounds,the destruction of the semiconductor chip, for example, silicon chip, forming the sensor being completely avoided during the injection moulding. An injection moulding tool (1, 2) has a mould cavity (14) corresponding to the desired shape of the casing and sensitive regions of the chip surface are protected against exposure to pressure during injection moulding by shielding components (10, 12, 13) disposed in the mould cavity. With a specified number of mould cavities (14), a corresponding number of injection mouldings can be produced simultaneously in the sensor housing mould with semiconductor chips integrated therein. <IMAGE>

Abstract: Conventional drive units for motor vehicles, in particular tractors, consist essentially of an internal combustion engine, of at least one downstream gearbox, and of a drive shaft for driving the front and/or rear wheels. In order also to be able to drive a vehicle of this kind in an infinitely variable manner for relatively low travelling speeds, it is proposed, in addition to the conventional drive unit, to provide a hydraulic drive unit which acts on the drive shaft (14) of the motor vehicle. The hydraulic drive unit can be coupled to the drive shaft (14) of the motor vehicle by a gearshift sleeve (62) or multi-plate clutch. An interlock circuit ensures that the hydraulic drive unit is only in engagement with the drive shaft (14) when the conventional drive unit has been decoupled from the power train.

Abstract: A flame retardant fibre material is produced by immersing vegetable fibre into a first inorganic compound solution and then into a second inorganic compound solution. Both solutions enter into the gaps between the vegetable fibres and contact each other to produce an insoluble and incombustible inorganic compound which is deposited on the fibres in the gaps therebetween. The thus deposited inorganic compound imparts flame retardant properties to the vegetable fibre.

Abstract: A high capacity metropolitan area network (MAN) is described. Date traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024x1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. Distributed control of the space division switch permits several million connection and disconnection actions to be performed each second, while the pipelined and parallel operation within the control means permits each of the 256 switching modules to process at least 50,000 transactions per second. The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is requied for transmitting each group of chained packets from a data switching module to a concentrator. MAN provides security features including a port identification supplied by the data concentrators, and a check that each packet is from an authorized source user, transmitting on a port associated with that user, to an authorized destination user that is in the same group (virtual network) as the source user. Distributed control of the space division switch is implemented by dividing that switch into disjoint sets of connection and switching elements and controlling each such set with a different controller. These controllers communicate via a separate control network with the data switching modules which request circuit connections.

Abstract: The specification described a process for making a plating mask 17, for use in printed wiring board fabrication, with greater precision and definition that has previously been possible. An insulative substrate 11 includes on one surface a thin metal film (13). The film is covered with a relatively thick first mask layer (16) which is selectively removed to expose portions of the metal film, which are in turn removed to expose portions of the insulative substrate (11). The exposed portions of the insulative substrate are covered with a relatively thick plating mask layer (17) which abuts against the first mask layer (16). The first mask layer is then removed, leaving the remaining plating mask layer as a patterned plating mask which is then used as a mask for deposited metal (19) which defines a printed circuit.

Abstract: A continuous paper sheet having a plurality of trans­versal perforation lines and a plurality of holes formed in the longitudinal margines of the paper sheet. The paper sheet is torn by means of two pairs of nipping rollers in­cluding a pair of the upper and the lower feed-in rollers (26a,26b) and another pair of the upper and the lower pulling rollers (27a,27b). The pulling rollers of the latter pair rotate higher than that of the feed-in rollers of the former pair so that the part of the sheet placed between the former pair of rollers and the latter pair of rollers are pulled or given tension, being torn and separated. After the continuous paper sheet is con­firmed that it is placed on a stand at the predetermined position, the width or distance of the continuous paper sheet folded is measured. The resultant of measurement is compared to the standard sizes previously inputted in a CPU in order to correct it to the approximate standard size. According to the corrected standard size and the sheet thickness separately measure, the tearing-up operation of the pairs of the feed-in rollers and of the high speed or pulling rollers is controlled in order to give the continuous paper sheet a difference in transferring speed and to tear-up the sheet at the predetermined position of the sheet.
