Inventor: SOLO DE ZALDIVAR JOSE
IPC: H01L29/78
Filed: 1992-12-16
Abstract: A method of manufacturing a semiconductor device comprising a field effect transistor and a device manufactured by this method in which a high packing density can be realised. The field effect transistor comprises a gate electrode (31,41) which is separated from a channel region by a first insulating layer (8) and is entirely surrounded by insulating material. For this purpose, a conductive layer (9) which is to form a gate electrode (31,41) is covered with a second insulating layer (10) and both layers are subsequently given the same pattern at least at the area of the channel region. As a result, the gate electrode (31,41) is covered at the upper side with a portion of the second insulating layer (10). The gate electrode (31,41) is laterally insulated by the provision of a third insulating layer (13) which is subsequently etched back anisotropically, whereby a portion (14) thereof remains intact afterwards alongside the side wall of the gate electrode (31,41). At least the source (32,42) or the drain (33,43) of the transistor is provided with an electrical connection (20) which makes contact through a contact window (19) in a further insulating layer (16). Due to the complete insulation of the gate electrode (31,41), said contact window (19) is allowed to overlap the associated gate electrode (31,41), so no alignment tolerances need be taken into account relative to the gate electrode (31,41) for forming this window (19).

Abstract: A laser interferometer uses an acousto-optically modulated laser (100) to produce a pair of orthogonally polarised frequency-shifted beams. The beams are passed down a monomode, polarisation preserving optical fibre (110) in order to transmit the beams to a cavity (148). The beams are separated at polarising beam splitter (128) and directed down measuring arm (130) and reference arm (132) of an interferometer. The beat frequency between the reflected beams is detected at photo-detector (146) which outputs a measuring signal (152). This beat frequency is compared to the beat frequency of the beams before entering the interferometer, which is derived by providing a semi-silvered mirror (114) and interfering polaroid (116) in the path of the beams up-beam of the interferometer to produce a reference signal (126). The measuring and reference signals are compared to determine the movement of the measuring arm of the interferometer. This method of determining the reference signal makes the apparatus less susceptible to temperature changes.

Abstract: The invention relates to pilot assisted direct sequence spread spectrum links. Fine code synchronisation generally requires either multiple receiver correlators (early/prompt/late) or jittered receiver correlators (Tau dither). The present invention removes the need for either by jittering the pilot code at source so that the receiver only needs to examine a single code phase and can generate a fine code phase steering signal from the difference between the pilot energy measured when transmitted early and measured when transmitted late.

Abstract: In order to maintain parasitic inductances of main electrodes at low levels also during operation of a semiconductor device, upright portions (1c, 2c, 3c) of main electrode plates (1, 2, 3) serving as paths of main currents are sealed in a side wall portion of a resin case, whereby the main electrode plates (1, 2, 3) are fixed to the case while being maintained in parallel with each other. Further, lower end portions (1b, 2b) are opposed in parallel with each other through a flat insulating spacer (12). Thus, parasitic inductances caused in the main electrode plates (1, 2, 3) are suppressed. Further, the lower end portions (1b, 2b, 3b) are not fixed to a circuit board but electrically connected to a power transistor through wires. Therefore, no deformation of the main electrodes (1, 2, 3) is brought by thermal deformation of the circuit board following heat generation of the transistor, whereby the parallelism of the main electrode plates (1, 2, 3) is maintained also during the operation of the device. Consequently, the parasitic inductances are maintained at low levels also during operation of the device.
