Abstract: Methods for facilitating fabricating semiconductor structures are provided which include: providing a multilayer structure including a semiconductor layer, the semiconductor layer including a dopant and having an increased conductivity; selectively increasing, using electrochemical processing, porosity of the semiconductor layer, at least in part, the selectively increasing porosity utilizing the increased conductivity of the semiconductor layer; and removing, at least in part, the semiconductor layer with the selectively increased porosity from the multilayer structure. By way of example, the selectively increasing porosity may include selectively, anodically oxidizing, at least in part, the semiconductor layer of the multilayer structure.

Abstract: In a solid-state lighting apparatus, a lamp body is provided with a solid-state light module and a detachable module space in the lamp body. A detachable module is provided exterior to the lamp body prior to insertion and which is insertable into the detachable module space and has contacts engageable with corresponding contacts in the module space. The detachable module has an internal circuit for controlling the solid-state light module.

Abstract: In one aspect, a lateral MOS device is provided. The lateral MOS device includes a gate electrode disposed at least partially in a gate trench to apply a voltage to a channel region, and a drain electrode spaced from the gate electrode, and in electrical communication with a drift region having a boundary with a lower end of the channel region. The device includes a gate dielectric layer in contact with the gate electrode, and disposed between the gate electrode and the drain electrode. The channel region is adjacent to a substantially vertical wall of the gate trench.

Abstract: A semiconductor device includes a graded junction termination extension. A method for fabricating the device includes providing a semiconductor layer having a pn junction, providing a mask layer adjacent to the semiconductor layer, etching the mask layer to form at least two laterally adjacent steps associated with different mask thicknesses and substantially planar step surfaces, and implanting a dopant species through the mask layer into a portion of the semiconductor layer adjacent to the termination of the pn junction. The semiconductor layer is annealed to activate at least a portion of the implanted dopant species to form the graded junction termination extension.

Abstract: Disclosed is a method for enhancing absorption of a medicament that is suitable for administering transmucosally to a subject by providing an environment of the administration with a suitable pH. A medicament of propranolol suitably administered sublingually is provided. The medicament of propranolol can be used for treating cardiovascular diseases.
