Patent TW-395082-B (TW)
Title: Low power, high linearity log-linear control method and apparatus
Inventor: CARGILL ROBERT S
IPC: H03G7/00
Filed: 1998-02-03
Granted: 2000-06-21
Abstract: Low power, high linearity log-linear control method and apparatus wherein a master log-linear cell generates a control voltage that is buffered and applied to a slave log-linear cell. By breaking this function up into two pieces, the control loop characteristics are isolated from the signal path. Low impedance buffers can be used to drive the slave log-linear cell control ports, independent of the control loop, providing improved gain control range and linearity. This log-linear control is of particular value in applications that require low harmonic distortion and high gain control range in power or pin-constrained applications. Details of the method are disclosed.

Title: Method of manufacturing embedded DRAMs
Inventor: LIOU FU-TAI
IPC: H01L27/108
Filed: 1998-07-06
Granted: 2000-01-11
Abstract: The present invention provides the method of manufacturing embedded DRAMs by making the surface of the memory circuit region and the surface of the logic circuit region at the same height, increasing thus the planarization of the IC. The invention provides a manufacturing process by leaving in the contact vent of height-length-width ratio fusion resistant metal oxide and using hydrogen plasma for processing or hydrogen heat treatment for changing the fusion resistant metal oxide remaining in the contact vent of the conductivity from nonconductor to conductor. Thus, the fusion resistant metal oxide left in the height-length-width contact vent can be partly selected by using hydrogen plasma treatment or hydrogen heat treatment. The treated part of the fusion resistant metal oxide is converted into conductor as contact connection and the untreated part of fusion resistant metal oxide shall remain as insulator for the dielectric layer of the DRAM capacitor.

Title: New etch process for forming high aspect ratio trenches in silicon
Inventor: WANG YI-CHIUNG
IPC: H01L27/108
Filed: 1998-10-28
Granted: 2000-07-01
Abstract: A multistep etch process for forming high aspect ratio trenches in silicon having a silicon oxide and/or silicon nitride hardmask. In a first step, an etch composition of HBr and oxygen is used, depositing a passivation layer on the sidewalls and producing slightly tapered openings. In the second step, an etch composition of a fluorine-containing gas such as SF6, HBr and oxygen is used, producing more vertical openings at a high etch rate. The taper of the openings during the second step can be controlled by adjusting the relative amount of HBr or SF6 smployed. This process is a clean process that does not require cleaning of the etch chamber between etch steps.

Title: System and method for holographic storage using a holographic optical element
Inventor: CAMPBELL SCOTT PATRICK
IPC: G02B5/32
Filed: 1998-11-11
Granted: 2001-11-21
Abstract: Embodiments of the invention include a holographic memory system (HMS), apparatus and method of holographic storage in which a holographic optical element (HOE) is used advantageously to reconstruct the reference beam arm in a holographic memory system such as a phase correlation multiplexing (PCM) holographic memory system. The holographic memory system includes a data storage device such as a holographic memory cell (HMC), the holographic optical element (HOE) for generation of the HMC reference beam (HOE object beam), an HOE reference beam that illuminates the HOE for generation of the HMC reference beam, and an HMC object beam that contains the information ultimately desired to be stored in the HMS. The holographic optical element (HOE) is formed in a holographic storage material such as a photopolymer, a photoresist, a thermoplastic material, a photorefractive material or a photochromatic material. The holographic optical element (HOE) reconstructs the stored HOE object beam upon illumination by the HOE reference beam. The reconstructed HOE object beam is then used as a reference beam for holographic storage of information in the data-encoded HMC object beam. The data storage device is placed in the path of the HMC reference beam (HOE object beam) and the HMC object beam to intersect therewith in a common volume for holographic storage of the resulting interference pattern formed thereby. The holographic optical element (HOE) is generated or formed in a holographic storage material by interfering the HOE object beam with the HOE reference beam in such a way that the pattern is storable within the holographic storage material. Once generated, the holographic optical element (HOE) apparatus replaces the reference arm optical arrangement within a holographic memory system, thus eliminating the complicated, delicate and expensive reference mask, lens and filter arrangement required of many holographic memory system in generating a reference beam.

Title: Enhanced domain name service
Inventor: HUITEMA CHRISTIAN
IPC: G06F17/30
Filed: 1998-11-11
Granted: 2000-07-21
Abstract: A system prefetches most frequently used domain names and stores the domain name data at local cache servers.  It generates validity codes to enable error checking for valid domain names at the local cache servers without accessing root servers.  A cache server obtains, stores, and propagates updates or new DNS data to local cache servers at predetermined intervals.  Users can obtain internet protocol addresses of domain names directly from local cache servers, thus eliminating processing delays over the Internet.

Title: Method for improved sputter etch processing
Inventor: HAUSMANN GILBERT
IPC: H01L21/68
Filed: 1999-07-28
Granted: 2001-01-01
Abstract: Method for processing a semiconductor substrate in a chamber comprising the steps of establishing preprocess conditions in the chamber, executing a two-step plasma ignition, processing the substrate, executing a two-step plasma power down and executing a two-step substrate dechuck. A ""softer"" ignition of a plasma in two steps reduces DC bias spikes on the substrate. Reducing DC bias spikes reduces processing anomolies such as excess charge retention in the wafer after removing the chucking voltage and wafer repulsion and plasma discontinuity during processing. Additionally, the plasma ramp down after processing allows adequate time for discharging of residual charges in the wafer which allows for more reliable removal of the substrate from the chamber (dechucking).
