Patent EP-0258383-B1 (EP)
IPC: H01L21/30
Filed: 1987-01-27
Granted: 1990-09-05
Abstract: A masked ion beam lithography (MIBL) system and method which is considerably more compact and economical than prior ion implantation devices. An H+ ion beam is extracted from a source (4) in the form of an angularly expanding beam, and is transmitted through two lenses (14 and 16) that sequentially accelerate the ions to energies in the range of 200-300 keV. The first lens (14) focuses the beam so that it emerges from a crossover point with an amplified angular divergence at least three times the divergence of the initial beam, thereby considerably reducing the necessary column length. The second lens (16) collimates the beam so that it can be directed onto a mask (32) to expose resist on an underlying semiconductor substrate (36). A series of extraction electrodes (58 and 60) are used to provide an initial point source beam with a desired angular expansion, and a specially designed sector magnet (8) is positioned between the extraction mechanism (6) and the first lens (14) to remove particles heavier than H+ from the beam. Voltage ratios across the lenses (14 and 16) and extraction electrodes (58 and 60) can be varied in tandem, permitting control over the final beam energy by a simple voltage adjustment. The beam is aligned with the column axis and then steered into alignment with the mask channeling axis by a pair of octupole lenses (13 and 30).

Abstract: In a matrix array of nonvolatile memory cells, each cell (36) includes a floating gate (47) coupled by large and small capacitances (46, 44) to first and second substrate regions (42, 43). The cell (36) further includes first and second select transistors (49, 51) having gate electrodes enabled by a row line and source/drain paths coupled respectively between the first and second substrate regions (42, 43), and first and second column lines (IOC1, R1). The first and second substrate regions (42, 43) communicate with corresponding second and first substrate regions of adjacent cells in the row. Programming and reading of the cell involves applying appropriate voltages to the first and second column lines (IOC1, R1) and the first column line (I1C2) of an adjacent cell. Such sharing of column lines between adjacent cells enables a high packing density to be achieved.

Title: Cross-correlation apparatus and methods
IPC: G01P3/80
Filed: 1989-07-20
Granted: 1993-03-03
Abstract: An apparatus and method for processing first and second signals, the second signal representing information which is delayed in time with respect to corresponding information represented by the first signal and there being included in the information represented by each signal information which represents a common effect, occurring at the same time, in each of the two signals. The apparatus includes correlating means which generate first data suitable for producing a positive time correlation curve from the two signals and second data suitable for producing the equivalent of a negative time correlation curve from the two signals or an autocorrelation curve from either one of the two signals. The information representing the common effect results in data common to both first and second data. One of the first and second data is therefore subtracted from the other, thereby removing or substantially reducing the information representing the common effect. The apparatus and method are particularly suited for measuring the speed of travel of a cable in a cable making machine, where lateral movements of the cable away from its desired path produce a common effect on sensors spaced lengthwise of the direction of travel.
