A method for depositing a coating comprising a polymer and pharmaceutical agent on a substrate, comprising the following steps: discharging at least one pharmaceutical agent in a therapeutically desirable morphology in dry powder form through a first orifice; discharging at least one polymer in dry powder form through a second orifice; depositing the polymer and/or pharmaceutical particles onto said substrate, wherein an electrical potential is maintained between the substrate and the pharmaceutical and/or polymer particles, thereby forming said coating; and sintering said coating under conditions that do not substantially modify the morphology of said pharmaceutical agent.

Polymer coatings containing drug powder of controlled morphology

A method for depositing a coating comprising a polymer and at least two pharmaceutical agents on a substrate, comprising the following steps: providing a stent framework; depositing on said stent framework a first layer comprising a first pharmaceutical agent; depositing a second layer comprising a second pharmaceutical agent; Wherein said first and second pharmaceutical agents are selected from two different classes of pharmaceutical agents.

Coatings containing multiple drugs

A coated coronary stent, comprising a stainless steel sent framework coated with a primer layer of Parylene C, and a rapamycin-polymer coating having substantially uniform thickness disposed on the stent framework, wherein the rapamycin-polymer coating comprises polybutyl methacrylate (PBMA), polyethylene-co-vinyl acetate (PEVA) and rapamycin, wherein substantially all of the rapamycin in the coating is in amorphous form and substantially uniformly dispersed within the rapamycin-polymer coating.

Facilitating throughput in nanoimprint lithography processes by using an imprint resist including fluorinated components and a substrate treated with a pretreatment composition to promote spreading of an imprint resist on the substrate. The interfacial surface energy between the pretreatment composition and air exceeds the interfacial surface energy between the imprint resist and air by at least 1 mN/m, and the contact angle of the imprint resist on the surface of the nanoimprint lithography template is less than 15&#xb0;.

Methods for processing a microelectronic topography include selectively etching a layer of the topography using an etch solution which includes a fluid in a supercritical or liquid state. In some embodiments, the etch process may include introducing a fresh composition of the etch solution into a process chamber while simultaneously venting the chamber to inhibit the precipitation of etch byproducts. A rinse solution including the fluid in a supercritical or liquid state may be introduced into the chamber subsequent to the etch process. In some cases, the rinse solution may include one or more polar cosolvents, such as acids, polar alcohols, and/or water mixed with the fluid to help inhibit etch byproduct precipitation. In addition or alternatively, at least one of the etch solution and rinse solution may include a chemistry which is configured to modify dissolved etch byproducts within an ambient of the topography to inhibit etch byproduct precipitation.

Drying a microelectronic topography. At least some of the illustrative embodiments are methods that include placing a microelectronic topography inside a process chamber, providing a non-aqueous liquid to the process chamber until at least 90% of the volume of the process chamber contains the non-aqueous liquid, pressurizing the process chamber by way of a fluid different than the non-aqueous liquid, ceasing activity with respect to the process chamber until the non-aqueous liquid and fluid form a mixture that is substantially homogenous, venting the process chamber while simultaneously providing the fluid to the process chamber, and venting the process chamber in a manner which prevents formation of liquid in the process chamber.

A method for depositing a coating comprising a polymer and pharmaceutical agent on a substrate, comprising the following steps: discharging at least one pharmaceutical agent in a therapeutically desirable morphology in dry powder form through a first orifice; discharging at least one polymer in dry powder form through a second orifice; depositing the polymer and/or pharmaceutical particles onto the substrate, wherein an electrical potential is maintained between the substrate and the pharmaceutical and/or polymer particles, thereby forming the coating; and sintering the coating under conditions that do not substantially modify the morphology of the pharmaceutical agent.

Methods for preventing feature collapse subsequent to etching a layer encasing the features include adding a non-aqueous liquid to a microelectronic topography having remnants of an aqueous liquid arranged upon its surface and subsequently exposing the topography to a pressurized chamber including a fluid at or greater than its saturated vapor pressure or critical pressure. The methods include flushing from the pressurized chamber liquid arranged upon the topography and, thereafter, venting the chamber in a manner sufficient to prevent liquid formation therein. The topography features may be submerged in a liquid while pressurizing the chamber. A process chamber used to prevent feature collapse includes a substrate holder for supporting a microelectronic topography, a vessel configured to contain the substrate holder, and a sealable region surrounding the substrate holder and the vessel. The chamber is configured to sequester wet chemistry supplied to the vessel from metallic surfaces of the sealable region.
