Disclosed is a circuit system generating a reference current (Iref) and an oscillator circuit which comprises said circuit system and a capacitor (8) that is connected to the input of a voltage-controlled source of electric power (1). Said capacitor (8) is triggered by two inter-switchable amplifiers (4, 6) with different driving capacities (gm1, gm2). According to said principle, an LC oscillator (14), for example, can be electrically controlled while being fed with the reference current (Iref) at a particularly low noise level.

The integrated circuit has a clock input for an external clock signal and an output unit controlled by an internal clock signal in a normal mode of operation to output data to a data output. In addition, the integrated circuit has a control unit generating the internal clock signal from the external clock signal. The control unit has a phase shift unit that, in the normal mode of operation, effects a phase shift of the internal clock signal generated by the control unit with respect to the external clock signal. In addition, the integrated circuit has a detector unit determining the capacitive load on the data output. The detector unit supplying the phase shift unit with a corresponding detector signal on the basis of which the phase shift is set.

The invention relates to a circuit arrangement for controlling a programmable connection (1), comprising a volatile memory cell (5), which is coupled to the fuse (1) for permanently memorising the data that is stored in the volatile memory (5) and a shift register (3), which permits data to be read from the volatile memory cell (5) and data to be written to the memory cell (5). To control several fuses (1), several shift registers (3) can be interconnected to form a shift register chain. Said shift register chain (3) enables the rapid reading from and writing to the volatile memory (4), using a circuit of low complexity.

In a controller (100) for controlling a generator system on a memory chip, the controller operates as a state machine in accordance with a state diagram including a plurality of X states. A state storage device (106) is responsive to input signals indicating a change in the state diagram from a current state to a next state for generating a revised plurality of X state output signals comprising a true State signal and a complementary true State signal for the next state of the plurality of X states. An output arrangement (108) is responsive to the true State signal and the complementary true State signal in the revised plurality of X state output signals from the state storage device for generating separate predetermined ones of M output signals associated with said next state for controlling the generator system while providing substantially zero current consumption when the state diagram reaches a final state of the plurality of X states.

A fiber optic cable that includes an armor layer having inner and outer surfaces and defining a passageway therethrough, a protective jacket surrounding the armor layer, a plurality of optical fibers extending lengthwise through the passageway, and a water swellable element for inhibiting water migration through the passageway. The water swellable element can be a water swellable layer on at least one of the inner and outer surfaces of the armor layer and/or a water swellable yarn extending through the passageway. The fiber optic cable is preferably tubeless, i.e., free of buffer tubes. In instances in which a water swellable layer is on the inner surface of the armor layer, the optical fibers are capable of contacting the water swellable layer. Alternatively, in instances in which the fiber optic cable includes water swellable yarns but not a water swellable layer on the inner surface of the armor layer, the optical fibers are capable of contacting the armor layer and, more particularly, the plastic coating of the armor layer. The fiber optic cable can exhibit shape retention whereby the fiber optic cable can retain a bent shape.

Eine Vorrichtung zum Herstellen einer nichtlösbaren Verbindung zwischen wenigstens zwei Lichtwellenleitern, insbesondere eines Schmelzspleißes, weist ein Gestell (1), an dem eine die Enden wenigstens zweier miteinander zu verbindenden Lichtwellenleiter an einer Fügestelle zueinander ausrichtende Führung (2) und Mittel (5) zum Verbinden der Lichtwellenleiter im Bereich der Fügestelle angeordnet sind, und wenigstens eine bewegbar ausgebildete Haube (7), mit der das Gestell (1) zumindest im Bereich der Fügestelle abdeckbar ist, auf. Um bei einer solchen Vorrichtung eine vergleichsweise einfache und schnelle Bedienung zu erzielen, ist ein durch die Haube (7) betätigbarer Schalter (9) vorgesehen, durch den die Mittel (5) zum Verbinden der Lichtwellenleiter im Bereich der Fügestelle derart schaltbar sind, daß sie in einer ersten Stellung der Haube (7) eingeschaltet und in einer zweiten Stellung der Haube (7) ausgeschaltet sind.

Zur Belichtung von photoempfindlichen Schichten wird die von einer Strahlungsquelle (5) emittierte, im extremen Ultraviolettbereich liegende Strahlung (4) über die Maske (11) auf die photoempfindlichen Schichten geführt.
摘要:
Applying heat and pressure to a backing film (3) comprising an adhesive layer (4) during the procedure of mounting it to a polish head (1) for use in chemical mechanical polishing (CMP), inhomogeneities inside the adhesive layer (4), e.g. thickness and compressibility variations or air bubbles (101), can easily be removed. A corresponding arrangement comprises a means for exerting a uniform pressure force (51), which can be a roller (51a) made of silicone or rubber, or a plate (51b), a means for heating (61) and a control unit (5) for controlling the heat and the pressure force. The backing film (3) installed using this Arrangement and method provides a uniform removal of material from the semiconductor wafer (2) surface and therefore advantageously increases the wafer yield.
摘要:
Using an algorithm for adding additional waiting times (60) to the process times of consecutively arranged processing devices (30) in a control unit (1) of a semiconductor device mass-production process line, the build-up of queues can be avoided resulting in equal time differences between any two manufacturing steps (101-118). The semiconductor devices (10) - the process line being the lithographic step comprising coating 104, exposure 112 and developing 116 - acquire stable process conditions and the yield is significantly increased due to a larger process window.
