摘要:
A method for forming a semiconductor structure includes forming a plurality of features across a surface of a substrate, with at least one space being between two adjacent features. A first dielectric layer is formed on the features and within the at least one space. A portion of the first dielectric layer interacts with a reactant derived from a first precursor and a second precursor to form a first solid product. The first solid product is decomposed to substantially remove the portion of the first dielectric layer. A second dielectric layer is formed to substantially fill the at least one space.

A low-thermal-budget gapfill process is provided for filling a gap formed between two adjacent raised features on a strained-silicon substrate as part of a shallow-trench-isolation process. An electrically insulating liner is deposited using atomic-layer deposition and polysilicon is deposited over the electrically insulating liner, with both stages being conducted at temperatures below 700° C.

A variety of techniques may be employed, separately or in combination, to improve the gap-filling performance of a dielectric material formed by chemical vapor deposition (CVD). In one approach, a first dielectric layer is deposited using sub-atmospheric chemical vapor deposition (SACVD), followed by a second dielectric layer deposited by high density plasma chemical vapor deposition (HDP-CVD) or plasma-enhanced chemical vapor deposition (PECVD). In another approach, a SACVD dielectric layer is deposited in the presence of reactive ionic species flowed from a remote plasma chamber into the processing chamber, which performs etching during the deposition process. In still another approach, high aspect trenches may be filled utilizing SACVD in combination with oxide layers deposited at high temperatures.

Embodiments of the present invention provide methods, apparatuses, and devices related to chemical vapor deposition of silicon oxide. In one embodiment, a single-step deposition process is used to efficiently form a silicon oxide layer exhibiting high conformality and favorable gap-filling properties. During a pre-deposition gas flow stabilization phase and an initial deposition stage, a relatively low ratio of silicon-containing gas:oxidant deposition gas is flowed, resulting in formation of highly conformal silicon oxide at relatively slow rates. Over the course of the deposition process step, the ratio of silicon-containing gas:oxidant gas is increased, resulting in formation of less-conformal oxide material at relatively rapid rates during later stages of the deposition process step.
摘要:
An apparatus, method, and computer program product for instant remote document serving. In one implementation, referred to as “remote document serving,” a remote file is converted to a “served document” which is distributed to a member of a data conference for review. In another implementation, referred to as “remote application serving,” the “owner” of a remote document views the screens created by a remote application associated with the document. The owner can view the screens and interact with the remote application.

A method and a computer program product, implementing techniques for exchanging data in an unattended desktop sharing mode. The techniques include receiving a conferencing request, at a local unattended server, from a remote conferencing server; loading a desktop application on the local unattended server in response to the conferencing request to generate a loaded desktop; sending the loaded desktop to a virtual device to create a shared desktop; and sending the shared desktop to the remote conferencing server for distribution to one or more remote computers, whereby the shared desktop is displayed at each remote computer by a viewer application.

A self-calibrating video circuit comprises a first and second digital-to-analog converter generating first and second output signals, and a calibration circuit coupled with the first and second digital-to-analog converters for calibrating the first digital-to-analog converter output signal to the output signal of the second digital-to-analog converter.
摘要:
An in-situ, two step or combination, method and system for cleaning of semiconductor manufacturing equipment is provided. The present invention utilizes two separate fluorine based chemistries in each step which selectively target the removal of different types of deposits that build up on the equipment surfaces. In particular, powdery and dense film-like solid deposits, as well as a combination of both, build up on the chamber surfaces and associated equipment components. These two types of deposits are removed selectively by the present invention. Such selective targeting of combined cleaning steps, yields an improved cleaning technique. In another embodiment, the method and system of the present invention provides for cleaning of the chamber and associated equipment using separate steps with different chemicals, and then performing these steps in a variety of desired sequences.
