| 20100144140 | METHODS FOR DEPOSITING TUNGSTEN FILMS HAVING LOW RESISTIVITY FOR GAPFILL APPLICATIONS - Methods of filling gaps or recessed features on substrates are provided. According to various embodiments, the methods involve bulk deposition of tungsten to partially fill the feature followed by a removing a top portion of the deposited tungsten. In particular embodiments, the top portion is removed by exposing the substrate to activated fluorine species. By selectively removing sharp and protruding peaks of the deposited tungsten grains, the removal operation polishes the tungsten along the feature sidewall. Multiple deposition-removal cycles can be used to close the feature. The filled feature is less prone to coring during CMP. | 06-10-2010 |
| 20100159694 | METHOD FOR DEPOSITING THIN TUNGSTEN FILM WITH LOW RESISTIVITY AND ROBUST MICRO-ADHESION CHARACTERISTICS - Methods of forming low resistivity tungsten films with good uniformity and good adhesion to the underlying layer are provided. The methods involve forming a tungsten nucleation layer using a pulsed nucleation layer process at low temperature and then treating the deposited nucleation layer prior to depositing the bulk tungsten fill. The treatment operation lowers resistivity of the deposited tungsten film. In certain embodiments, the depositing the nucleation layer involves a boron-based chemistry in the absence of hydrogen. Also in certain embodiments, the treatment operations involve exposing the nucleation layer to alternating cycles of a reducing agent and a tungsten-containing precursor. The methods are useful for depositing films in high aspect ratio and/or narrow features. The films exhibit low resistivity at narrow line widths and excellent step coverage. | 06-24-2010 |
| 20100267230 | METHOD FOR FORMING TUNGSTEN CONTACTS AND INTERCONNECTS WITH SMALL CRITICAL DIMENSIONS - Provided are methods of void-free tungsten fill of high aspect ratio features. According to various embodiments, the methods involve a reduced temperature chemical vapor deposition (CVD) process to fill the features with tungsten. In certain embodiments, the process temperature is maintained at less than about 350° C. during the chemical vapor deposition to fill the feature. The reduced-temperature CVD tungsten fill provides improved tungsten fill in high aspect ratio features, provides improved barriers to fluorine migration into underlying layers, while achieving similar thin film resistivity as standard CVD fill. Also provided are methods of depositing thin tungsten films having low-resistivity. According to various embodiments, the methods involve performing a reduced temperature low resistivity treatment on a deposited nucleation layer prior to depositing a tungsten bulk layer and/or depositing a bulk layer via a reduced temperature CVD process followed by a high temperature CVD process. | 10-21-2010 |
| 20100267235 | METHODS FOR DEPOSITING ULTRA THIN LOW RESISTIVITY TUNGSTEN FILM FOR SMALL CRITICAL DIMENSION CONTACTS AND INTERCONNECTS - Provided are methods of void-free tungsten fill of high aspect ratio features.

| 20110159690 | DEPOSITING TUNGSTEN INTO HIGH ASPECT RATIO FEATURES - Methods and apparatuses for filling high aspect ratio features with tungsten-containing materials in a substantially void-free manner are provided. In certain embodiments, the method involves depositing an initial layer of a tungsten-containing material followed by selectively removing a portion of the initial layer to form a remaining layer, which is differentially passivated along the depth of the high-aspect ration feature. In certain embodiments, the remaining layer is more passivated near the feature opening than inside the feature. The method may proceed with depositing an additional layer of the same or other material over the remaining layer. The deposition rate during this later deposition operation is slower near the feature opening than inside the features due to the differential passivation of the remaining layer. This deposition variation, in turn, may aid in preventing premature closing of the feature and facilitate filling of the feature in a substantially void free manner. | 06-30-2011 |

Each feature set includes feature integers quantized from interest points of a corresponding image. An initial set of clusters of the feature sets is found based on min hashes of the feature sets. Given the clusters of feature sets, descriptors for each of the clusters are computed, respectively, by selecting feature integers from among the feature sets in a cluster. The clusters are then refined by comparing at least some of the feature sets with at least some of the cluster descriptors, and based on such comparing adding some of the feature sets to clusters whose feature descriptors have similarity to the feature sets. | 12-15-2011 |
