Abstract: A semi-conductor device is manufactured by forming on a silicon substrate 101, source and drain diffusion layers 103 and 104, an insulation film 102, a gate film 105, a gate electrode 106 and an insulation film 107. A contact hole 108 is formed through the films 107 and 105 and a bottom electrode 109 for a ferro-electric film is formed on the film 107 and in the hole 108. A ferro-electric film 110 of PbTiO₃ or PZT or PLZT is sputtered onto the electrode 109 and film 107 and it is treated by ion implantation of Pb to correct the composition thereof to stoichiometric composition. Thereafter, annealing takes place at above 500°C to improve the crystalline characteristics of the film. A top electrode 111 is formed on the shaped film 110 and the whole protected by a passivation layer 112.

Title: Metallization processing
Inventor: LU CHIH-YUAN
IPC: H01L21/28
Filed: 1990-09-21
Abstract: When forming a metallization layer(14), an integrated-circuit semiconductor device fabrication metal such as tungsten, for example, adheres poorly to a dielectric such as, e.g., silicon oxide, and tends to flake off from wafer areas not covered by a glue layer. Processing of the invention prevents such flaking by, first removing the dielectric(11) from the back side, edge, and "clip-mark" areas of the wafer and, second, depositing a glue layer(13) on remaining dielectric(11) on the face of the wafer. Removal of dielectric material(11) is by etching in the presence of a protective layer(12) on the face of the wafer.

Abstract: A mounting assembly for a meter unit (17) and/or stop-cock valve assembly (16) has a pair of one-way valves (40, 41) downstream of the meter unit (17) and/or stop-cock valve assembly (16). The one-way valves (40, 41) are separated by a spacer ring (42) with an opening therein leading to a duct defined by a chamber (44) and a passage (52, 56). The duct is normaly sealed by an end cap 58, but removal of that end cap 58 permits immediate pressure measurement of the fluid (e.g. water) between the two one-way valves (40, 41) which substantially corresponds to the outlet pressure. Furthermore, if the stop-cock valve assembly is operated to seal against a valve seat 20 and so stop incoming fluid flow, then the second one-way valve 41 can be tested by checking for flow from the duct corresponding to a back-flow from the outlet pipe 28 of the mounting assembly.

Abstract: Disclosed is a method of decompressing data mode up of a sequence of literal references, history references, and lexicon references. The method includes the steps of reading a reference from the sequence and emitting a lexicon string if the reference is of the type lexicon, emitting a history string if the reference is of the type history, and emitting a literal string if the reference is of the type literal. The string emitted is inserted into a history buffer and if the string is of the type history it is inserted in a lexicon.

Abstract: Registration of an image with respect to a recording medium in a film recorder or the like is provided by first roughly positioning the recording medium in a support. A beam is then scanned across an unused portion of the recording medium until it impinges a fixed reference mark such as a sprocket hole edge. The coordinates of the beam are determined at the reference mark, and a registration signal is computed therefrom. The beam is then scanned across the recording medium in response to the registration signal to record information in registered relation to the reference mark. An intensity profile of the beam is calculated as it passes over an edge of the recording medium. The focus of the beam is then adjusted according to the intensity profile. Adjustment of both beam focus and lens focus is provided.

Abstract: A compensated amplitude comparison monopulse receiver (10) having an angular measurement capability substantially unaffected by mismatches in channel transient response and target range tracking inaccuracy is disclosed herein. The inventive monopulse receiver (10) includes a first receiver channel (24) for impressing a first output voltage S1 on a first output port (28) thereof in response to excitation by a sum signal. A second receiver channel (26) impresses a second output voltage S2 on a second output port (30) thereof in response to excitation by the sum and a difference signal. In a calibration mode, a calibration source (22) provides a series of calibration pulses to the first and second channels (24, 26) which induces first and second calibration voltages to appear on the first and second output ports (28, 30) thereof. Sampling gates (32, 34) sample the first and second calibration voltages subsequent to application of each calibration pulse to the first and second receiver channels (24, 26). In a tracking mode the sample gates (32, 34) are operative to sample the first and second output voltages present on the first and second output ports (28, 30). The inventive receiver 10 further includes circuitry (48, 50) for calculating the angular location of the first object from the sampled first and second output voltages. A compensation network (36) then adjusts the calculated angular location on the basis of the sampled calibration voltages.

Abstract: When the horizontal size of a display character is given by 9 dots, 8-dot font data is stored in a font register (16), and 1-dot display attribute data is stored in a register (17). Display attribute data is data for designating the 8th dot of a character pattern to be displayed. A selector (18) converts 9-dot data supplied from the font register (16) and the register (17) to serial data on the basis of a counter value (CD) of a counter (19) and supplies the serial data to a CRT (4) when 80 characters are to be displayed in the horizontal direction on the CRT (4) having a horizontal resolution of 720 dots per scanning line. When an FPD (5) having a horizontal resolution of 640 dots per scanning line is to be used, the selector (18) converts only 8-dot font data supplied from the font register (16) to serial data on the basis of a counter value (CD) from the counter (19) and supplies the serial data to the FPD (5). As a result, eighty 8-dot characters are displayed in the horizontal direction of the FPD (5) despite that display of 9-dot characters is designated. However, the numbers of display characters of the CRT (4) and the FPD (5) in the horizontal direction coincide.

Abstract: A vehicle roof is disclosed, having a stretchable cover part which comprises a flexible material and comprises relatively rigid frame parts which are assigned to the front and rear transverse sides and are connected to one another by means of tensioning elements which run in the longitudinal direction. The cover part can be completely removed from the vehicle roof in order to uncover the roof opening provided in the fixed roof surface and then can be stowed in the collapsed state. In one embodiment, one transverse side of the cover part is held on the vehicle by means of a holder which is constructed in the manner of a door hinge whilst the opposite transverse side is detachably connected by means of a quick-release safety fastener to the fixed roof surface or to the frame which is fixed to the body of the vehicle. In an alternative embodiment, both transverse sides and both frame parts of the cover part are assigned frame-part quick-release safety fasteners which are constructed in an essentially matching fashion and are arranged symmetrically. In both embodiments, in the closed state the flexible material of the cover part is reliably held in the stretched state in such a way that it is pressed against the peripheral seal on the roof frame in order to obtain a sealed closure in the closed position of the cover part.
