Patent MX-9707616-A (MX)
Title: Method for manufacturing a low dielectric constant inter-level integrated circuit structure.
Inventor: BOECK BRUCE ALLEN
IPC: H01L21/28
Filed: 1997-10-03
Abstract: An interconnect structure having a dielectric layer with low dielectric constants formed within integrated circuit. In one embodiment of the invention, portions of a silicon dioxide layer (18) embodiment of the invention, portions of a silicon dioxide layer (18) lying adjacent to a conductive interconnect (21) are removed to expose portions of a silicon nitride etch stop layer (16). A dielectric layer (22) having a low dielectric constant is then formed overlying the conductive interconnect (21) and the exposed portions of the silicon nitride etch stop layer. (16). A portion of the dielectric layer (22) is then removed to expose the stop surface of the conductive interconnect (21) to leave portions of the dielectric layer (22) between adjacent conductive interconnects (21). The resulting interconnect structure has reduced croos-talk between conductive interconnects (21) while avoiding prior art disadvantages of reduced thermal dissipation and increased mechanical stress.

Patent NL-6906145-A (NL)
IPC: H04L9/12
Filed: 1969-04-21
Abstract: A message to be transmitted in binary form over a signal channel to a remote terminal is scrambled by being passed through an Exclusive-OR gate which logically combines its bits in pseudo-random fashion with bits of a quasi-aperiodic code sequence to generate a scrambled binary message; a similar Exclusive-OR gate at the receiving terminal logically combines the bits of that scrambled message with corresponding bits from a like quasi-periodic code sequence to reproduce the original message. The circuits delivering the two code sequences are concurrently reset, at irregular intervals, by a predetermined succession of code combinations transmitted over the channel.

Patent NL-8020484-A (NL)
IPC: H03H19/00
Filed: 1980-11-24
Abstract: The electronic filter has three integrating operational amplifiers (12, 14, 16) connected in series. An input voltage (Vin) to be filtered is supplied during alternating clock pulses (phi, phi') to the first integrator (12) from a capacitor (30) and to the capacitor for storage, respectively, by way of MOS switching devices (18-24). Capacitances (40, 44) are connected in a feedback loop of the first amplifier, of which the output is connected via capacitor (68) and MOS switches (58, 62, 70, 72) to the inverting input of the second integrator (14). The stray capacitances are eliminated effectively by the additional pair of switches for each switched capacitor, by the alternate charging and discharging of the stray capacitors on the alternate clock pulses. A third order elliptic filter characteristic is achieved having two complex conjugate poles, a real pole and two complex conjugate zeroes. Magnitudes of the zeroes are not affected by the capacitor valves alpha i, where i equals 1, 2... . In the transfer function, the magnitude of the transmission zero is the constant term of the quadratic factor in the numerator and is always unity no matter what the capacitor values are.

Title: Electrolytic etching of aluminium - uses improved alternating current waveform for more efficient etching
IPC: C25F3/04
Filed: 1981-06-16
Abstract: Etching is carried out by applying an a.c. to Al in contact with an electrolyte contg. HCl. The wave form of the current rises rapidly from 0 to a maximum and then decreases rapidly to an intermediate value a third to a half of the maximum. Decrease to zero then occurs more slowly. The ratio of first stage time to second stage time is 1-6. Higher capacitance values of the etched Al are obtd. The process is used to increase the surface area of Al foil used for capacitor electrodes. The wave form produces higher capacitance foil than square, sinusoidal or saw-tooth wave forms. The etching process is at least 10% more efficient.

Title: Distance measuring device laser light source - has optics emitting light beam in measuring range optics projecting reflected light onto detector
IPC: G01S17/08
Filed: 1987-09-25
Abstract: The device for measuring distances has a laser light source with a first optical system with which a laser beam is emitted in the direction of a measuring range. There is also a positionally sensitive light detector and a second optical system with which light, reflected by an object in the range, is projected onto the detector. A supply circuit excites the laser source and is controlled by a signal which can vary the intensity of the emitted light rays within predetermined limits. The detector is connected to an intensity detecting circuit producing an output signal whose strength is related to the intensity. This light intensity dependent signal is compared in a threshold value circuit, to stimulate the supply circuit. Thus with an intensity dependent signal over the threshold value, the laser source provides a relatively high power for measuring purposes.
