Abstract:
PROBLEM TO BE SOLVED: To provide a time savable alternative method for taking out a microscopic sample from a substrate. SOLUTION: The method for taking out the microscopic sample 1 from the substrate 2 comprises a step of performing a cutting process where the substrate 2 is irradiated with a beam 4 so as to cut out the sample 1 from the substrate 2, and a step of performing an adhering process where the sample 1 is adhered to a probe 3. In at least a partial period of the duration of the cutting process, the cutting process is simultaneously by at least two beams 4 and 5. The cutting by at least two beams allows extraction of the sample 1 without changing the azimuth of the substrate 2 related to a beam generating means. The possibility of simultaneously operating two beams and keeping constant azimuth provides time saving comparing with a method of performing the cutting with a single beam.

Abstract:
A pressure sensor die assembly comprises a base substrate having a first surface, a stop structure on the first surface, and a diaphragm structure coupled to the first surface. The diaphragm structure comprises a first side with a cavity section including a first cavity and a second cavity surrounding the first cavity; a pressure sensing diaphragm portion having a first thickness and defined by the first cavity; and an over pressure diaphragm portion having a second thickness and defined by the second cavity, the second thickness greater than the first thickness. When an over pressure is applied, at least some area of the pressure sensing diaphragm portion is deflected and supported by the stop structure. As over pressure is increased, the over pressure diaphragm portion deflects and engages with the first surface such that additional area of the pressure sensing diaphragm portion is deflected and supported by the stop structure.
Abstract:
A process for fabricating a suspended microelectromechanical system (MEMS) structure comprising epitaxial semiconductor functional layers that are partially or completely suspended over a substrate. A sacrificial release layer and a functional device layer are formed on a substrate. The functional device layer is etched to form windows in the functional device layer defining an outline of a suspended MEMS device to be formed from the functional device layer. The sacrificial release layer is then etched with a selective release etchant to remove the sacrificial release layer underneath the functional layer in the area defined by the windows to form the suspended MEMS structure.
