Patent EP-0239384-A3 (EP)
IPC: H01L21/31
Filed: 1987-03-25
Abstract: A process is disclosed for improving the isolation 
between semi-oxide insulated devices, formed on mesa 
structures. In the fabrication of such devices, a silicon 
substrate is provided. Patterned regions of one type of 
conductivity are formed in a major surface of the sub­
strate and an epitaxial layer of silicon is formed on the 
substrate over the major surface. A patterned mask layer 
is formed on the epitaxial layer and is etched to expose 
portions of the epitaxial layer. The exposed portions of 
the epitaxial layer are removed to form the mesa struc­
tures, which overlie the doped patterned regions. Regions 
of opposite conductivity, called channel stops, are then 
formed in the substrate between the patterned regions. 
After filling in the areas between the mesa structures 
with a field oxide, the devices (bipolar or MOS transis­
tors) are formed on the mesa structures.  
     The process of the invention utilizes as a mask 
structure a mask having a combination of properties (com­
position and thickness) related to the subsequent process­
ing. The mask permits use of an anisotropic etchant to 
define the mesa structures and to undercut the mask. An 
oxide layer is formed on the side walls of the mesa struc­
tures and on those portions of the substrate exposed 
during the mesa-defining step. Those portions of the 
oxide layer underlying openings in the mask structure are 
removed to expose portions of the substrate, which encom­
pass regions between the doped patterned regions. The 
channel stop dopant is introduced into the regions between 
the patterned regions.

IPC: G06F13/16
Filed: 1987-08-18
Abstract: In may situations, contiguous data is not stored at contiguous locations 
within a memory. This fact alone causes an increase in processor time for 
retrieval purposes or the intervention of a memory management unit of some 
type. The situation is compounded when large amounts of data must be 
obtained from the memory or stored in the memory in real time. This problem 
is addressed by arranging a dual ported memory between the main memory (11) 
and the processor (10) and transferring the desired data into the dual ported 
memory. A pair of buffers (block0, block1) in the dual ported memory is then 
used for each channel having access to the memory. While one buffer is being 
read, the other is being loaded. This structure also allows multiple devices to 
access the single main memory substantially simultaneously. [FIG. 1]
Patent EP-0274192-A3 (EP)
IPC: G02B6/24
Filed: 1987-11-02
Abstract: An optical fiber submarine cable splice housing (10) includes a pressure 
vessel arranged for securely terminating an optical fiber cable (22) and an 
optical fiber (11). A metallic tube (14) formed into a helix is fixed to the cable 
termination (12). The optical fiber extends from the terminated cable and 
through the tube to a fiber termination on the splice housing (15). The tube 
acts like a capstan for the optical fiber so that a small tensile force at the fiber 
termination will hold the fiber in place while a much larger tensile force exists in 
the fiber where it leaves the cable termination. This optical fiber submarine 
cable splice housing is arranged substantially in accordance with the Figure.

Title: Antireflection coatings for use in photolithography
IPC: H01L21/027
Filed: 1988-04-15
Abstract: Reflection of incident optical radiation (18) from a highly reflective metal layer (12), such as aluminum or titanium, into a photoresist layer (14) is reduced by interposing a layer of titanium nitride (16) between the metal and photoresist layers. The thickness of the TiN layer depends on the wavelength of the optical radiation used to expose the photoresist and on the optical properties of the underlying metal layer. Reflectance of less than about 2% may be achieved using the TiN layer in conjunction with aluminum and less than about 5% in conjunction with titanium, in accordance with the invention. If left in place after patterning an underlying aluminum layer, the TiN layer also serves to suppress hillock formation in the aluminum layer.

Filed: 1988-06-13
Abstract: An interferometer used as a rotation sensor is 
constructed using a strand of optical fiber (112), a 
portion of which is formed into a sensing loop (114). A 
pair of lightwaves (W₁, W₂) are caused to counterpropagate 
in the sensing loop (114) and are combined to form an 
optical output signal that has an intensity that varies in 
accordance with the difference in the phases of the two 
counterpropagating lightwaves (W₁, W₂). A phase modulator 
(192) is positioned on the optical fiber (112) in the 
sensing loop (114) at a location such that the two 
counterpropagating lightwaves (W₁, W₂) are modulated 
approximately 180° out of phase. The time-varying phase 
modulation causes a time-varying phase difference (ΔΦ M (t)) 
that is combined with a rotationally-induced Sagnac effect 
phase to provide a total phase difference that is detected 
by a photodetector (160). The photodetector (160) provides 
an electrical output signal this is differentiated to 
provide a differentiated output signal (520, 450, 460) that 
has zero-crossings (H′, L′) that correspond to maxima and 
minima of the electrical output signal. The time intervals 
(Δt₁′) between selected zero-crossings (H′, L′) are 
measured and the rotationally-induced phase difference 
(ΔΦ R ) caused by the Sagnac effect is calculated from the 
measured time intervals (Δt₁′) The rotation rate (Q) is 
then calculated from the Sagnac phase difference (ΔΦ R ).

with binary information introduced to the converter. The 
generator is responsive to binary signals each having first and 
second logic levels respectively representing binary "1" and 
binary "0" and each representing a different one of the binary 
colors red, green and blue. Each of the binary signals is 
introduced to an individual one of transistors in a first 
plurality. An energizing voltage is also introduced to the 
transistors to obtain a flow of current through such transistors 
in accordance with the logic levels of such input signals and 
the magnitude of the energizing voltage. A substantially 
constant current is provided at first particular times and a 
reference voltage is provided at other times. An impedance may 
be common to the circuit for the substantially constant current 
and the reference voltage. A first control is responsive to the 
constant current to maintain the energizing voltage at a 
substantially constant value. A second control is responsive to 
the reference voltage to maintain the energizing voltage at the 
substantially constant value. When the reference voltage is 
produced, the production of the substantially constant voltage 
from the constant current is overridden. The first and second 
controls for each of the different colors are disposed in an 
electrical circuit to provide an output from the circuit only in 
accordance with the logic levels of the binary signals. The 
first and second controls may respectively include transistors 
in second and third pluralities.

Title: Demodulator with multiple interference cancellers responsive to correlations between undesired signals and error signals
IPC: H04B1/10
Filed: 1989-11-27
Abstract: Undesired signals detected by a main antenna (1) are cancelled by 
corresponding interference cancelling signals. The output of the main 
antenna is frequency converted to IF region and decomposed into first and 
second main baseband components. Decision circuits are provided for 
making a decision on whether each of the first and second main baseband 
components exceeds each of multiple thresholds and produces multibit 
codes as well as error signals. Auxiliary antennas (3-1...3-m) 
respectively detect the undesired signals and feed auxiliary frequency 
converters (5-1) for translating the frequency of the respective outputs 
of the auxiliary antennas to the intermediate frequency. Auxiliary 
quadrature demodulators (7-1) are provided for respectively decomposing 
the output of each auxiliary frequency converter into first and second 
auxiliary baseband components. Correlations (8-1,9-1) are detected 
between the first auxiliary baseband components and the first error 
signal and between the second auxiliary baseband component and the second 
error signal. Amplitude and phase controllers (6-1) are responsive to the 
detected correlations to control the outputs of the auxiliary 
frequency converters to generate the interference cancelling signals. 
Variable length delay lines (4-1) are associated respectively with the 
auxiliary antennas for introducing delays so that both cancelling 
signals and corresponding interfering components are time-coincident 
at the summing circuit.
