IPC: H01L21/768
Filed: 1987-08-27
Abstract: Deposited silicon dioxide may be used as a field oxide layer or for other dielectric purposes in integrated circuits. However, etching a pattern in the layer usually produces steep sidewalls that prevent good step coverage of subsequently deposited conductor layers. The present technique forms the dielectric in at least two layers (e.g., 11,12) having different densities. A sequence of anisotropic and isotropic etching results in stepped sidewalls (14-17), providing good linewidth control and good step coverage of subsequently deposited material.

Abstract: A gyro-stabilised mechanism that is to be carried on a vehicle, such as a helicopter, is provided with a protective enclosure consisting of a dome, usually of glass fibre reinforced plastic. The dome must be provided with a window (44) transparent to the radiation involved, and this must be steered with the mechanism so that they remain in register with one another. Prior art structures employ elongated windows of sufficiently large size to accommodate the tilting and rolling of the mechanism, while pan movements are accommodated by rotating the entire dome. The invention provides a structure employing a small window that can be steered or slaved with the mechanism by rotation of the part 56 of the dome including the window relative to the other part 46, which has the pan or yaw rotation motor connected to it. This rotation between the dome parts takes place in a skew plane disposed at as small a skew angle to the vertical as is possible, the compensation for the resulting transverse movement of   the window being effected by a programmed rotation of the dome about the pan axis. Optically flat glass can then be used for the window, it can be coated to reduce reflections, etc. and it can also be wiped in operation to remove moisture. A broadcast antenna 126 can be mounted on the part of the dome out of the line-of-sight of the apparatus.

Abstract: Each element of an array of infrared detector elements comprises a capacitor formed by a body (11) of pyroelectric or ferroelectric material between a front electrode (14) and a back electrode (12). The elements have individual electrical connections (13) to their back electrode (12) from which there are derived electrical signals which differ as the temperature of the body (11) changes in response to incident infrared radiation (50). These individual electrical connections (13) are provided by a pattern of conductors (13) carried by a support (10) on which the elements are mounted. Each element has at least an infrared-collection area (21) of larger lateral dimensions (x) than at least the electrical connection (13) to the back electrode (12) whereby a peripheral part (23) of each element overhangs and is separated vertically from an underlying part of the support (10). In accordance with the invention, the elements are arranged in a 2-dimensional array with inner elements of the array surrounded by outer elements of the array. The conductors (13) to the inner elements extend on a part of the support (10) between the outer elements and below the overhanging peripheral parts (23) of these outer elements. These conductors (13) of the inner elements are separated from the back electrode (12) and overhanging peripheral parts (23) of the outer elements and from the individual electrical connections (13) of these outer elements by a gap (y,z) sufficient to avoid any troublesome parasitic capacitance across a detector element or any significant capacitive cross-talk between the detector elements. The width of the intermediate conductor tracks (13) and the dimensions (y,z) of the surrounding gap may be larger than the spacing between the overhanging peripheral parts (23) of adjacent elements and, for example, as large as or larger than the thickness of the element bodies (11). The array can be fabricated cheaply and reliably using thick-film techiques to form the conductors (13) on a good thermally insulative support (10), so also providing low thermal cross-talk between the detector elements.

Abstract: In a multiplex system for automotive vehicles, battery (+V) current is supplied to a load (70) connected to a non-intelligent slave unit (20) via a power switch (TR) in the slave controlled by a capacitor (CT) which is charged or discharged in an assigned time slot by high or low drive voltage applied on a low current signal line (42) from a remote intelligent unit (10). If the load (70) goes short-circuit then a thyristor (TH) adjacent the power switch (TR) turns on to turn off the power switch (TR) and provide a discharge path for the capacitor (CT) via the load (70), this discharged condition being detected at the remote intelligent unit during an assigned load driving time slot. Thus a dedicated extra channel (time slot) is not required at the slave unit for short-circuit testing of the load.

Abstract: A signal source which provides a carrier signal (31) having a precisely set signal-to-noise ratio is provided. The carrier signal (31) and its sideband noise components (33) are attenuated below the equivalent thermal noise floor (35) of an attenuator (13). The attenuated carrier signal (31) and the equivalent thermal noise floor (35) are then amplified in an amplifier (15) having a known noise figure to produce a composite carrier signal having a usable power level and a precisely known signal-to-noise ratio. Since the equivalent thermal noise floor (35) is a function only of temperature, the desired carrier signal-to-noise ratio may be set by setting the power level of the carrier signal (31) and knowing the noise figure of the amplifier (15).
