IPC: H01L21/768
Filed: 1997-06-19
Abstract: A method of forming a metal plug 18 in a contact hole (19) formed in a insulating layer 13 on a silicon substrate 11, comprises depositing a metallic barrier layer 14, e.g. of Ti and TiN, over the whole structure, depositing first and second metal layers 15,(16) on the barrier layer, e.g. by CVD or PVD, etching away most of the second metal layer to leave only a portion 16a on the side walls of the contact hole, forming a third metal layer 17 over the first and remaining portion of the second layer such that the third layer fills the hole, and then etching the first and third metal layers to leave a metal plug 18 in the hole. The first and third metal layers are preferably of the same material selected from the group Al, Cu and W. The second metal layer may be TiN, Ru, RuO 2 or WN 2 . The side wall portions 16a of the second metal layer induce growth of the metal of the third layer in the hole in a single direction, thereby preventing overetching in the final etching step.

Title: Multiplex addressing of ferroelectric liquid crystal diplays
Inventor: JONES JOHN CLIFFORD
IPC: G09G3/36
Filed: 1996-12-12
Abstract: A ferroelectric liquid crystal display comprises a layer of ferroelectric liquid crystal material contained between two cell walls, surface treated to align the material in a tilted layer. The walls carry e.g. row and column electrodes forming an x,y matrix of addressable elements or pixels. Multiplex addressing voltages are provided by driver circuits. An improved addressing is obtained by varying the addressing voltage applied during switching of a pixel to maximise torque applied on liquid crystal molecules. Addressing voltages are from two data waveforms and one strobe waveform; the data waveforms have three or more time slots per period forming a line address time, two or more voltage levels, dc balance, and equivalent rms. values; the strobe waveform has two or more voltage levels (which may include a zero level). The strobe and data waveforms combine to provide switching and non-switching resultant waveforms that form an addressing voltage at each pixel. The switching resultant waveform has gradually increasing voltage levels throughout a line addressing time. The non-switching resultant waveform has a first voltage of opposite polarity to that of the later voltage levels which may include one or more levels of sufficiently large amplitude to inhibit switching.

Title: Arrangement for enhancing signal integrity on a bus
Inventor: GABARA THADDEUS JOHN
IPC: H03K19/0175
Filed: 1998-02-10
Abstract: Controllable impedance arrangements (60) are provided for coupling to one or more integrated circuit components 20a-20f coupled along a bus transmission line (24) within a communications system, to establish damping impedances for selected devices between the signal transmitting component and the signal receiving component along the bus transmission line to advantageously reduce distortion and ringing associated with the LC parasitic network behavior of the devices. Typically, a damping impedance is coupled to the integrated circuit component immediately adjacent to the signal transmitting component along the bus. Alternatively, other integrated circuit components between the signal transmitting component and the signal receiving component have damping impedances coupled thereto in addition to or instead of the integrated circuit component adjacent to the signal transmitting component. The controllable damping impedance arrangements are on-chip or off-chip configurations of switchable impedance elements that, when actuated, couple the necessary impedance to the characteristic capacitance and associated inductance of selected integrated circuit components. The damping impedance arrangements are controlled by a controller 72 operably coupled to the arrangement or by other suitable means. Implementation of the damping impedance arrangements advantageously improves the integrity of signals transmitted along the bus transmission line and reduces ringing without unnecessarily increasing power dissipation and/or driving power requirements of the signal transmitting components within the communications system.

Title: Analysis of alignment data
Inventor: NOWER DANIEL L
IPC: G01B21/24
Filed: 1998-03-18
Abstract: To determine the condition of a machine (22, 24) having a first shaft (16) coupled to a second shaft (18), alignment fixtures (12, 14) on the shafts produce alignment data composed of data points purportedly corresponding to the misalignment between the shafts (16, 18) measured at a plurality of rotational positions relative to the shafts. An alignment analyser (30) having an input (26, 28) for receiving the alignment data analyses the alignment data, eg by determining the best fit sine curve, to produce a confidence factor indicating the probability that the alignment data corresponds to the misalignment of the shafts. A rotationally isolated machine fault may be detected by deleting sets of data points and determining the confidence factors of the reduced data. An output such as a display (34) associated with said analyser (30) outputs information corresponding to the alignment data and the condition of the machine (22, 24).

Title: Projecting optical apparatus
Inventor: TSUJI TOSHIHIKO
IPC: G03F7/20
Filed: 1987-01-21
Abstract: PURPOSE:To shorten the down time of an apparatus, by holding the history data of fluctuation in characteristics of an optical projecting system even if an unexpected state such as power failure occurs, and correcting the data after the power is recovered. CONSTITUTION:When the normal projection of objects is interrupted by, e.g., power outage, predicted data for the fluctuation in characteristics of images at the time of interruption are stored in a memory Q4 by a battery backup part Q6. A timer Q5 starts counting. When a power source is recovered, a time required for the recovery is inputted into a CPU Q1 from the timer Q5. The stored data in the memory Q4 is also inputted into the CPU Q1. In the CPU Q1, the correct predicted data of the fluctuation of the image forming characteristics in the optical projecting system at the time of the recovery of the power source is obtained based on the inputted data, and the image forming characteristics of the optical projecting system are controlled. Thus the down time of the system is shortened.
