Abstract: A method for fabricating a multilayer microstructure with balancing residual stress capability includes forming a multilayer microstructure on a substrate and conducting a step of isotropic plasma etching. The multilayer microstructure includes a first metal layer, a second metal layer, a metal via layer and an insulating layer. The first metal layer and the second metal layer are patterned and aligned symmetrically so as to form etching through holes. The metal via layer surrounds each etching through hole. The insulating layer fills each etching through hole and is disposed between the substrate and the first metal layer. The step of isotropic chemical plasma etching removes the insulating layer in each etching through hole and the insulating layer between the substrate and the metal layer so as to form a suspended multilayer microstructure on the substrate.

Abstract: An inclined exposure lithography system is disclosed, which comprises: a substrate; a photoresist layer, formed on the substrate; a mask, disposed over the photoresist layer with a gap therebetween; and a refraction element disposed over the mask so that a light beam from a light source is refracted by a specific angle.

Abstract: A method and an apparatus are disclosed for scatterfield microscopical measurement. The method integrates a scatterometer and a bright-field microscope for enabling the measurement precision to be better than the optical diffraction limit. With the aforesaid method and apparatus, a detection beam is generated by performing a process on a uniform light using an LCoS (liquid crystal on silicon) or a DMD (digital micro-mirror device) which is to directed to image on the back focal plane of an object to be measured, and then scattered beams resulting from the detection beam on the object's surface are focused on a plane to form an optical signal which is to be detected by an array-type detection device. The detection beam can be oriented by the modulation device to illuminate on the object at a number of different angles, by which zero order or higher order diffraction intensities at different positions of the plane at different incident angles can be collected.
