20110266252 | HIGH-TEMPERATURE SELECTIVE DRY ETCH HAVING REDUCED POST-ETCH SOLID RESIDUE - Methods of dry etching silicon-containing dielectric films are described. The methods include maintaining a relatively high temperature of the dielectric films while etching in order to achieve reduced solid residue on the etched surface. Partially or completely avoiding the accumulation of solid residue increases the etch rate. | 11-03-2011 |
20140073144 | LOW COST FLOWABLE DIELECTRIC FILMS - A method of forming a dielectric layer is described. The method deposits a silicon-containing film by chemical vapor deposition using a local plasma. The silicon-containing film is flowable during deposition at low substrate temperature. A silicon precursor (e.g. a silylamine, higher order silane or halogenated silane) is delivered to the substrate processing region and excited in a local plasma. A second plasma vapor or gas is combined with the silicon precursor in the substrate processing region and may include ammonia, nitrogen (N | 03-13-2014 |
20140091417 | LOW REFRACTIVE INDEX COATING DEPOSITED BY REMOTE PLASMA CVD - A method of depositing a low refractive index coating on a photo-active feature on a substrate comprises forming a substrate having one or more photo-active features thereon and placing the substrate in a process zone. A deposition gas is energized in a remote gas energizer, the deposition gas comprising a fluorocarbon gas and an additive gas. The remotely energized deposition gas is flowed into the process zone to deposit a low refractive index coating on the substrate. | 04-03-2014 |
20140248754 | CONTROLLED AIR GAP FORMATION - A method of forming and controlling air gaps between adjacent raised features on a substrate includes forming a silicon-containing film in a bottom region between the adjacent raised features using a flowable deposition process. The method also includes forming carbon-containing material on top of the silicon-containing film and forming a second film over the carbon-containing material using a flowable deposition process. The second film fills an upper region between the adjacent raised features. The method also includes curing the materials at an elevated temperature for a period of time to form the air gaps between the adjacent raised features. The thickness and number layers of films can be used to control the thickness, vertical position and number of air gaps. | 09-04-2014 |
20140273430 | INTEGRATED CLUSTER TO ENABLE NEXT GENERATION INTERCONNECT - Embodiments of the present invention generally relate to methods for forming a metal structure and passivation layers. In one embodiment, metal columns are formed on a substrate. The metal columns are doped with manganese, aluminum, zirconium, or hafnium.
