Title: Method of fabricating notched-spacer memory cells
Inventor: JENG SYANG-YWAN
IPC: H01L21/8247
Filed: 2003-09-09
Granted: 2004-11-01
Abstract: A method to fabricate notched-gate memory cells with multi-bits per cell is disclosed. First, a gate insulation layer, a conductor layer and a patterned photoresist have been formed onto the semi-conducting substrate. By using the photoresist as an etching mask, the conductor layer has been etched to form the gate electrode. Before etching through the conductor layer, a thin residual conductor layer is intentionally remained. The first oxide spacer is then formed after removal of the patterned photoresist. The thin remaining conductor layer is then isotropic etched to form the notched-shape gate electrode with spacers as etching mask. After removing the oxide spacers and gate insulators, the second and third insulators are formed using conformal depositions to fill the under-cut portions of notched gates. A directional or anisotropic etch is used to etch back the third insulator to form the second spacer. Finally, the third spacer is then formed onto the side-wall of the second spacer.

Granted: 2007-03-21
Abstract: A method for processing a received communication which includes periodic transmissions of a set of information segments. A first transmission of the set of information segments is received and processed to identify each of the segments as valid or invalid. The valid segments of the first set are then stored. Where all segments of the set are not stored, subsequent transmissions of the set of information segments are received and only those segments not previously stored are processed to identify each such segment as valid or invalid. The valid segments so identified are then stored. Subsequent transmissions are repeatedly received unless all segments of the set have been stored.

Title: Circuit for modulating audio signals in two channels of television to generate audio signal of center third channel
Inventor: LIN OU-HUANG
IPC: H04N9/835
Filed: 2004-03-24
Granted: 2005-08-11
Abstract: The present invention provides a new circuit for modulating the audio signals in two channels of a television to generate an audio signal of a center third channel. In electronic circuits, the audio signals of right/left channels of three channels set by the TV/stereo circuits of the present invention are transmitted by two audio signal circuits respectively. The center voice band portions are then removed from the signals of two circuits to only keep the audio signals of the right/left channels. After another circuit is filtered by high-pass and low-pass filters and is then phase-compared by a phase comparator, the center audio signal of original audio signals is kept. Therefore, according to the design of the present invention, the audio signals inputted by branches of right/left channel circuits are processed by the circuits of the present invention to generate a pure audio signal of the left channel, a pure audio signal of a center channel and a pure audio signal of the right channel at the output ends of branches of the three circuits respectively. A 3D stereophonic sound is therefore generated.

Granted: 2007-05-21
Abstract: The present invention provides a structure of a heat conductive pipe and a method for producing the same. The invented structure includes a heat conduction housing tank for containing a working fluid. The bottom of the heat conduction housing tank is stacked with a plurality of support screens. A metal pipe is installed on the support screens and in the heat conduction housing tank. One type of powder is loaded in the space between the metal pipe and the heat conduction housing tank. A cover with an evacuation opening thereon is installed above the heat conductive housing tank. A sintering operation is performed on the heat conductive housing tank so that the powder is molten and formed into a porous heat conductive structure and formed into an interconnection with the heat conduction housing tank, the metal pipe, and the bottom-mounted copper screens. The heat dissipation efficiency of the invented structure is increased because the structure of the bottom-mounted copper screens is capable of storing a larger quantity of working fluid and increasing the nucleus boiling efficiency. Since the metal pipe and the cover are sintered simultaneously during the production process, a step of removing a metal rod required in a conventional process is eliminated. This alters the process in producing a heat conductive pipe and makes the production process simpler, thereby increasing the production efficiency of the heat conductive pipe.

Abstract: A method for fabricating a trench capacitor is disclosed. A substrate is etched to form a first trench recess with a first depth. A spacer layer is deposited on interior surface of the first trench recess. The spacer layer is anisotropic etched back to form a spacer on sidewall of the first trench recess, and through the first trench recess, continuing to etch the substrate so as to form a second trench recess with a second depth.

Through the second trench recess, etching continues to remove the substrate to form a deep trench recess with a third depth. The deep trench recess is thereafter doped to form a diffusion region at a lower portion of the deep trench recess. A capacitor dielectric layer is then formed under the self-aligned collar oxide layer on interior surface of the deep trench recess. The deep trench recess is filled with a first conductive layer. The first conductive layer is then recess etched to form a first conductive stud within the deep trench recess. The first conductive stud has a top surface that is lower than the surface of the substrate, but is higher than the self-aligned collar oxide layer.
