Abstract:
Drug delivery devices comprising a non-bioabsorbable polymer structure configured to support a composition comprising an active agent. The devices include a plurality of portions fused together and a recess configured to support the composition. At least one of the portions includes an impermeable polymer and at least one other portion includes a rate-limiting water- permeable polymer. The rate-limiting water-permeable polymer allows for transportation of the active agent to an exterior of the device.
Abstract:
A process of forming a front-grid electrode on a silicon wafer having an ARC layer, comprising the steps: (1) printing and drying a metal paste A comprising an inorganic content comprising 0.5 to 8 wt.-% of glass frit and having fire-through capability, wherein the metal paste A is printed on the ARC layer to form a bottom set of thin parallel finger lines, (2) printing and drying a metal paste B comprising an inorganic content comprising 0 to 3 wt.-% of glass frit over the bottom set of finger lines forming a top set of finger lines superimposing the bottom set of finger lines, (3) printing and drying a metal paste C comprising an inorganic content comprising 0.2 to 3 wt.-% of glass frit to form busbars intersecting the finger lines at right angle, and (4) firing the triple-printed silicon wafer, wherein the inorganic content of metal paste B as well as that of paste C contains less glass frit plus optionally present other inorganic additives than the inorganic content of metal paste A.

Abstract:
In an example embodiment, a linear wet system includes a carrier and a proximity head in a chamber. The proximity head includes three sections in a linear arrangement. The first section suctions liquid from the upper surface of a semiconductor wafer as the wafer is transported by the carrier under the proximity head. The second section is configured to cause a film (or meniscus) of cleaning foam which is a non-Newtonian fluid to flow onto the upper surface of the wafer. The third section is configured to cause a film of rinsing fluid to flow onto the upper surface of the wafer as the wafer is carried under the proximity head. The third section is defined partially around the second section and up to the first section, so that the third section and the first section create a confinement of the cleaning foam with respect to the chamber.
Abstract:
Methods and apparatus for controlling a plasma processing system in a purely pull mode or a hybrid pull mode, in the purely pull mode, the back end assumes master control at least for requesting and scheduling loading of production wafers. In the hybrid pull mode, the back end assumes master control at least for tool maintenance/cleaning while the front end retains master control for production wafers.
Abstract:
An upper processing head includes a topside module defined to apply a cleaning material to a top surface of a substrate and then expose the substrate to a topside rinsing meniscus. The topside module is defined to flow a rinsing material through the topside rinsing meniscus in a substantially uni-directional manner towards the cleaning material and opposite a direction of movement of the substrate. A lower processing head includes a bottomside module defined to apply a bottomside rinsing meniscus to the substrate so as to balance a force applied to the substrate by the topside rinsing meniscus. The bottomside module is defined to provide a drain channel for collecting and draining the cleaning material dispensed from the upper processing head when the substrate is not present between the upper and lower processing heads. The upper and lower processing heads can include multiple instantiations of the topside and bottomside modules, respectively.

Abstract:
Drug delivery devices comprising a non-bioabsorbable polymer structure and a composition comprising an active agent have been discovered. The drug delivery devices may be used to treat ocular conditions, among other diseases and conditions. In addition, a method of treating an ocular condition has been discovered comprising implanting a drug delivery device which releases the active agent at a rate of Q = 0.001 x N x C wherein C is the topical effective concentration (in milligram/mL) of the active agent and N=0.01 to 0.5 for prostaglandins in their ester, amide, free acid or salt form, and N=0.5 to 5 for any active agent other than prostaglandins in their ester, amide, free acid or salt form.
Abstract:
Methods configure a proximity head for conditioning fluid flow relative to a proximity head in processing of a surface of a wafer by a meniscus. The methods configure the head in one piece while maintaining head rigidity even as the head is lengthened for cleaning of large diameter wafers. The one-piece head configuring separates main fluid flows from separate flows of fluid relative to the wafer surface, with the separation being by a high resistance fluid flow configuration, resulting in substantially uniform fluid flows across increased lengths of the head in a unit for either fluid supply or return.
