Systems and methods for inspecting a wafer are provided. One system includes an illumination subsystem configured to illuminate the wafer; a collection subsystem configured to collect light scattered from the wafer and to preserve the polarization of the scattered light; an optical element configured to separate the scattered light collected in different segments of the collection numerical aperture of the collection subsystem, where the optical element is positioned at a Fourier plane or a conjugate of the Fourier plane of the collection subsystem; a polarizing element configured to separate the scattered light in one of the different segments into different portions of the scattered light based on polarization; and a detector configured to detect one of the different portions of the scattered light and to generate output responsive to the detected light, which is used to detect defects on the wafer.

A vacuum deposition method for fabricating high-strength nitinol films by sputter depositing nickel and titanium from a heated sputtering target, and controlling the sputter deposition process parameters in order to create high-strength nitinol films that exhibit shape memory and / or superelastic properties without the need for precipitation annealing to attenuate the transition conditions of the deposited material. A vacuum deposited nitinol film having high-strength properties equal to or better than wrought nitinol films and which are characterized by having non-columnar crystal grain structures.

Grids and collimators, for use with electromagnetic energy emitting devices, include at least a metal layer that is formed, for example, by electroplating / electroforming or casting. The metal layer includes top and bottom surfaces, and a plurality of solid integrated walls. Each of the solid integrated walls extends from the top to bottom surface and has a plurality of side surfaces. The side surfaces of the solid integrated walls are arranged to define a plurality of openings extending entirely through the layer. At least some of the walls also can include projections extending into the respective openings formed by the walls. The projections can be of various shapes and sizes, and are arranged so that a total amount of wall material intersected by a line propagating in a direction along an edge of the grid is substantially the same as another total amount of wall material intersected by another line propagating in another direction substantially parallel to the edge of the grid at any distance from the edge. Methods to fabricate these grids using copper, lead, nickel, gold, any other electroplating / electroforming materials, metal composites or low melting temperature metals are described.

An improved control panel assembly is easy to fabricate, and easy to recognize a selected operation condition, and a laundry device with the same. The control panel assembly for a laundry device includes a button assembly having a plurality of buttons provided in correspondence to operation conditions, a control panel having a plurality of mounting holes for exposure of the plurality of buttons therethrough from a front thereof, and a frame on a rear of the control panel, the frame joining the plurality of buttons as one unit, and preventing pressing interference between adjacent buttons.

An X-ray imaging device and alignment / scanning system include at least one multilayer X-ray mirror mounted on a multi-axis adjustable mirror mount pivotable about a scanning axis. A mirror scanner is coupled with the mirror mount and synchronized with the X-ray source so that the mirror scanner moves the mirror mount about the scanning axis. The invention may include a plurality of mirrors, optionally in a stack, and preferably including first and second mirrors respectively adapted to reflect X-rays of first and second energies. A movable attenuation plate having a window selectively allows X-rays to be transmitted by one of the mirrors and blocks X-rays from the other mirror(s). Sets of the mirrors may be configured in blocks or interspersed. The mirror scanner may be operable at variable speeds to enable selective control of the scanning speed of the mirror.

A power semiconductor device is provided having a field plate that employs a thick metal film in an edge termination structure and which permits edge termination structure width reduction even with large side etching or etching variation, which exhibits superior long-term forward blocking voltage capability reliability, and which allows minimal forward blocking voltage capability variation. The edge termination structure has multiple ring-like p-type guard rings, a first insulating film covering the guard rings, and ring-like field plates, provided via the first insulating film atop the guard rings. The field plates have a polysilicon film and a thicker metal film. The polysilicon film is provided on a first guard ring via first insulating film, and a dual field plate made of the polysilicon film and metal film is provided on a second guard ring. The dual field plate is stacked via a second insulating film. The first and second guard rings alternate.

Disclosed herein is an apparatus for cleaning a lubricant for dry-type wire drawing. The apparatus comprises a case provided with a cover and piercing holes at opposite sides of the case such that a steel wire can pass through the case, a plurality of driving motors provided at one side of the exterior of the case, rotating members located at an inside of the case and connected to the driving motors, respectively, by belts serving to rotate them, support plates for supporting the rotating members, and cleaning members coupled to the rotating member and adapted to provide a path through which the steel wire passes. The dry lubricant on the surface of the steel wire can be effectively cleaned by friction between the lubricant on the steel wire and the cleaning members.
