摘要： The invention relates to a method of making an integrated circuit inductor that comprises a silicon substrate and an oxide layer on the silicon substrate. In one aspect, the method comprises depositing an inductive loop on the oxide layer, and making a plurality of apertures in the oxide layer beneath the inductive loop. The method also comprises providing a plurality of bridges adjacent the apertures and provided by portions of the oxide layer between an inner region within the inductive loop and an outer region of the oxide layer without the inductive loop, the inductive loop being supported on the bridges. The method comprises forming a trench in the silicon substrate beneath the bridges, to provide an air gap between the inductive loop and the silicon substrate.

摘要： An inductor has a spiral aluminum track deposited on an oxide layer over a silicon substrate. The substrate is etched away to form a trench, which extends around beneath the track and provides an air gap having a low dielectric constant. The oxide layer has an inner region within the track, an outer region outside the track and a bridging region extending between the other regions. The bridging region is comprised of intact bridges and gaps therebetween, which are open to the trench and through which an etchant has access to the silicon substrate to form the trench by etching.

摘要： A method for forming a photovoltaic cell which includes forming a nanostructured layer in a semiconductor material having a plurality of pores opening onto a surface, the plurality of pores having a depth greater than about 1 micron and a diameter between about 5 nanometers and about 1,200 nanometers, and disposing an organic charge-transfer material in the pores of the nanostructured layer. A first electrode is attached to the semiconductor material, and a second electrode is attached to the organic charge-transfer material. The semiconductor material has a thickness between about 5 microns and about 700 microns. Desirably, the nanostructured layer has a porosity of less than the porosity corresponding to the percolation threshold, and the organic charge-transfer material extends at least about 100 nm from the surface of the nanostructured layer. The organic charge-transfer material may partially cover the sides of the pores of the nanostructured layer thereby providing a generally cylindrical cavity therein.

摘要： A built-in non-verbal compact instructional device integratable to an applicator having a microdevice for painlessly perforating skin and optionally an active agent for application to the perforated area. The microdevice can include microneedles, microneedle arrays, microblades, microblade arrays, microknives, microknife arrays, and Functional MicroArrays (FMAs). The active agent can be stored in a first chamber. The microdevice can perforate stratum corneum without significant pain or discomfort to a patient. The active agent is applied to the perforated area. The device verifies compliance with predetermined methods of use, such as a light to indicate application with the recommended amount of force for perforating skin. The applicator can provide enhanced delivery of an active agent, with minimal discomfort, for therapeutic or cosmetic treatment, such as topical treatment for acne, or other skin disorders, wrinkles, blemishes, etc. The applicator is also useful for providing improved systemic or localized delivery of an active agent.
