Title: Method for manufacturing CMOS
Inventor: LIN JIAN-TING
IPC: H01L21/8238
Filed: 1998-04-22
Granted: 2000-02-21
Abstract: A method for manufacturing a CMOS uses the difference between the masks used in the ring implantation and the implantation of the source/drain region to remove the restriction of implantation angle caused by the well receiving region. The method is to form the lightly doped drain structure in the well region and the photoresist layer of the ring implantation region out of the region specified for formation of the well receiving region in the well region, thereby increasing the distance between the photoresist layer and the gate, and reducing the restriction of the tilt angle that can be used in the ring implantation. The light doping on the region specified for the formation of the well receiving region can be compensated in the subsequent doping process to form the source/drain region of a non-well region, and formed into a predetermined well-receiving region.

Title: Frame-based audio coding with additional filterbank to attenuate spectral splatter at frame boundaries
Inventor: FIELDER LOUIS DUNN
IPC: G10L19/02
Filed: 1998-10-14
Granted: 2000-05-21
Abstract: Several audio signal processing techniques may be used in various combinations to improve the quality of audio represented by an information stream formed by splice editing two or more other information streams. The techniques are particularly useful in applications that bundle audio information with video information. In one technique, gain-control words conveyed with the audio information stream are used to interpolate playback sound levels across a splice. In another technique, special filterbanks or forms of TDAC transforms are used to suppress aliasing artifacts on either side of a splice. In yet another technique, special filterbanks or crossfade window functions are used to optimize the attenuation of spectral splatter created at a splice. In a further technique, audio sample rates are converted according to frame lengths and rates to allow audio information to be bundled with, for example, video information. In yet a further technique, audio blocks are dynamically aligned so that proper synchronization can be maintained across a splice. An example for 48 kHz audio with NTSC video is discussed.

Title: Method and apparatus for propagating a signal between synchronous clock domains operating at a non-integer frequency ratio
Inventor: KHANDEKAR NARENDRA
IPC: G06F1/10
Filed: 1998-12-04
Granted: 2001-10-11
Abstract: A method of transmitting a signal from a first clock domain to a second clock domain commences with the generation of first and second clock signals. The first and second clock signals are substantially synchronous and have respective frequencies that are non-integer multiples. A first signal, which is generated in the first clock domain responsive to a transition of the first clock signal that is substantially coincident with a transition of the second clock signal, is prevented from being latched in the second clock domain responsive to the transition of the second clock signal. The first clock signal is prevented from being latched for a time period which is greater than a maximum clock skew which may exist between the first and second clock signals.

Title: Positioning system for digital telephone networks
Inventor: DUFFETT-SMITH PETER
IPC: H04W64/00
Filed: 1998-12-10
Granted: 2001-03-11
Abstract: The invention relates to a determining the position of a mobile receiver 4 in a digital telephone network positioning system. A first receiver 3 is at a known location and others are mobile. The method involves transmitting signals from a plurality of sources 1, the transmission signals having a format at least a portion of which has predetermined values or a portion of which is repeated. The time offset of the transmission signals received at each receiver 4, 5 from a transmission source 1 relative to a reference clock of each receiver is determined by generating a reference signal locked to the reference clock. The reference signal has a similar format to the transmission signals and includes a portion identical to the predetermined values or repeated portion of the received signal and compares the received transmission signal and the reference signal. The time delay between the respective signals received at the receivers 4, 5 is determined from their relative time offset, to thereby determine the position of the other receivers 4.

Title: Method for fabricating ultra-low resistivity tantalum films
Inventor: CHIANG TONY
IPC: C23C14/16
Filed: 1999-09-10
Granted: 2003-02-11
Abstract: We have discovered that, by depositing a tantalum layer upon a substrate at a temperature of at least 325 DEG C, it is possible to obtain an ultra low resistivity which is lower than that previously published in the literature. In addition, it is possible to deposit a TaxNy film having an ultra low resistivity by depositing the TaxNy film upon a substrate at a temperature of at least 275 DEG C, wherein x is 1 and y ranges from about 0.05 to about 0.18. These films having an ultra low resistivity are obtained at temperatures far below the previously published temperatures for obtaining higher resistivity films. A combination of elevated substrate temperature and ion bombardment of the film surface during deposition enables the use of lower substrate temperatures while maintaining optimum film properties. In another development, we have discovered that the ultra low resistivity tantalum and TaxNy films produced by the method of the present invention also exhibit particularly low residual stress, so that they are more stable and less likely to delaminate from adjacent layers in a multilayered semiconductor structure. Further, these films can be chemical mechanical polished at significantly higher rates (at least 40% higher rates) than the higher resistivity tantalum and TaxNy films previously known in the industry. This is particularly useful in damascene processes when copper is used as the interconnect metal, since it reduces the possibility of copper dishing during a polishing step.

Title: Semiconductor memory
Inventor: NAMBU HIROAKI
IPC: G11C11/419
Filed: 2000-04-13
Granted: 2003-01-11
Abstract: A semiconductor memory in accordance with the present invention includes a sense amplifier composed of a plurality of MOS transistors. When the sense amplifier is on standby, a first control circuit brings an input signal of the sense amplifier to zero. A second control circuit uses voltages developed because of an offset voltage occurring in the sense amplifier to feed back the potentials in the wells of the MOS transistors so that the offset voltage will be nullified. When the offset voltage occurring in the sense amplifier is nullified, a delay time required by the sense amplifier is shortened. This results in the high-speed semiconductor memory.
