Patent application numberDescriptionPublished
20110207323Method of forming and patterning conformal insulation layer in vias and etched structures - Vias are formed in a substrate using an etch process that forms an undercut profile below the mask layer. The vias are coated with a conformal insulating layer and an etch process is applied to the structures to remove the insulating layer from horizontal surfaces while leaving the insulating layers on the vertical sidewalls of the vias. The top regions of the vias are protected during the etchback process by the undercut hardmask.08-25-2011

20100022030DRY ETCH STOP PROCESS FOR ELIMINATING ELECTRICAL SHORTING IN MRAM DEVICE STRUCTURES - The present invention relates generally to semiconductor fabrication and particularly to fabricating magnetic tunnel junction devices. In particular, this invention relates to a method for using the dielectric layer in tunnel junctions as an etch stop layer to eliminate electrical shorting that can result from the patterning process.01-28-2010
20100285237NANOLAYER DEPOSITION USING BIAS POWER TREATMENT - A hybrid deposition process of CVD and ALD, called NanoLayer Deposition (NLD) is provided. The NLD process is a cyclic sequential deposition process, comprising introducing a first plurality of precursors to deposit a thin layer with the deposition process not self limiting, followed by introducing a second plurality of precursors for plasma treating the thin deposited layer. The plasma can be isotropic, anisotropic, or a combination of isotropic and anisotropic to optimize the effectiveness of the treatment of the thin deposited layers.11-11-2010

20090035388ANTIMICROBIAL PHOTO-STABLE COATING COMPOSITION - The invention is an antimicrobial photo-stable coating composition that deters photo-induced discoloration, does not stain tissue and can be applied to the surface of a variety of medical materials. The composition comprises in an aspect silver-PCA complex and dye.02-05-2009
20110100293SYSTEM AND METHOD FOR COATING MEDICAL DEVICES - A system and method for photo-grafting a coating polymer onto the surface of a medical device are provided. The system comprises a plurality of stations including a novel grafting station. The system and method of the invention are both time- and resource-efficient. The system includes several stations, each station including a dipping tank. The system allows for the automated, semi-automated, or manual dipping of medical devices into the dipping tanks in a specified order, as desired, wherein at least one of the stations is a grafting station for photo-grafting the coating polymer onto the surface of the medical device. The system is modular, which allows for modification of the process as required, depending on the needs of the user. The system may comprise stations for incorporating an antimicrobial agent into the coating, and/or for rendering the coating lubricious.05-05-2011
