Title: Process for making a crystalline solid-solution powder with low electrical resistance
Inventor: LUPTON DAVID FRANCIS
IPC: H01B1/08
Filed: 1998-05-13
Granted: 2002-09-11
Abstract: A process for making a crystalline solid-solution powder which involves reacting at least two reactants in a plasma arc of a plasma chamber and blast-cooling the resultant product in a high velocity gas stream to form the powder. The first reactant is a molten metal alloy and the second reactant is a gas. The reaction is carried out in a plasma arc and the products rapidly cooled by a gas stream acting at the outlet opening of the plasma chamber. The crystalline solid-solution powder formed by the process has a low electrical resistivity. If an indium-tin alloy is used as the first reactant and oxygen as the second reactant, there is obtained an indium-tin-oxide (ITO) crystalline solid-solution powder which, when compacted to 40% of its theorectical density, has an electrical resistivity in the range of about 2 Ω cm. This ITO crystalline solid-solution powder is particularly suitable for preparing an ITO target, with high electrical conductivity and thus high achievable sputtering rates.

Title: Method of manufacturing self-aligned contact
Inventor: SHIU JEN-TSUNG
IPC: H01L21/60
Filed: 1998-06-12
Granted: 2001-05-28
Abstract: A method of forming self-aligned contact comprises the steps of forming a cap layer on top of a gate structure. Then, sidewall spacers are formed on each side of the gate structure, while a self-aligned contact opening is formed above the source/drain region. Next, a polysilicon plug that couples electrically with the source/drain region is formed inside the self-aligned contact opening. A metallic material is deposited to fill the self-aligned contact opening, thereby forming a metal plug. The polysilicon plug and the metal plug together form a self-aligned contact. Alternatively, a polysilicon plug that couples electrically with the source/drain region is formed inside the self-aligned contact opening, and fill the self-aligned contact opening thereby for forming a stud. Subsequently, the position occupied by the stud is replaced by a metal plug. Hence, a self-aligned contact is again formed.

Title: Planarization method with spin-on material
Inventor: JOU DA-CHENG
IPC: H01L21/76
Filed: 1998-08-21
Granted: 2001-08-11
Abstract: The present invention provides a planarization process with spin-on material using the dielectric as the etching stop layer. The process first forms one or more layers of dielectric on a layer of spin-on material on top of patterned metal block for filling up the trench between metal blocks. Then, a planarization process is performed on the spin-on material layer. While conducting the planarization process, because the dielectric underlying the spin-on material layer has an excellent selective ratio on the removing rate of spin-on material layer, the dielectric can be used as the removing stop layer to remove the spin-on material layer on top of the metal block and retain only the spin-on material layer between metal blocks. Finally, the dielectric on top of the metal block is removed to complete the planarization process.

Title: A sampled amplitude read channel employing a trellis sequence detector matched to a channel code constraint and a post processor for correcting errors in the detected binary sequence using the signal samples and an error syndrome
Inventor: BLISS WILLIAM G
IPC: H03M13/25
Filed: 1999-08-03
Granted: 2004-11-11
Abstract: A sampled amplitude read channel is disclosed for disk storage systems comprising a encoder/decoder for implementing a high rate channel code that codes out specific minimum distance error events of a trellis sequence detector by enforcing a particular code constraint. The trellis sequence detector comprises a state machine matched to the code constraint which effectively removes the corresponding minimum distance errors from the detected output sequence. Additionally, the channel code encodes redundancy bits into the write data for implementing an error detection code. The redundancy bits are processed during a read operation to generate an error syndrome used to detect and correct other dominant error events, such as the NRZ (+) and (+-+) error events. In this manner, the most likely error events of the trellis sequence detector are either coded out by the channel code constraint, or detected and corrected using the error syndrome. As a result, the present invention provides a significant distance enhancing performance gain over the prior art without decreasing the system's code rate, thereby providing a substantial increase in linear bit density and overall storage capacity.

Abstract: This invention provides a method to fabricate node capacitor for dynamic random access memory. Firstly, a word line gate electrode is formed on a semiconductor substrate and a silicon nitride layer and a first interpoly dielectric layer are deposited in order. A polycide bit line is formed in the first interpoly dielectric layer. A second interpoly dielectric layer is deposited and planarized. A defined photoresist layer is made on the second interpoly dielectric layer, which is employed as mask to etch part of the second interpoly dielectric layer and part of the polycide bit line to expose the first interpoly dielectric layer. The defined photoresist layer is removed. An oxide coil is deposited. The silicon nitride layer is exposed by etching part of the oxide coil and part of the first interpoly dielectric layer. Part of the silicon nitride layer is removed to expose the substrate and the word line gate electrode. Then, a first polysilicon layer is deposited. A bottom electrode is made by removing part of the first polysilicon layer and exposing the second interpoly dielectric layer. A thin ONO dielectric layer is formed on the bottom electrode and the second interpoly dielectric layer. There is an additional step before forming the thin ONO dielectric layer on the bottom electrode, which is the formation of a hemispherical grain (HSG) layer on the first polysilicon layer. The bottom electrode is thus made by removing part of the first polysilicon layer and part of the HSG layer to expose the second interpoly dielectric layer. A top electrode is formed by depositing a second polysilicon layer to fully cover the thin ONO dielectric layer.
