Abstract:
A technique for manufacturing a micro-electro mechanical structure includes a number of steps. Initially, a cavity is formed into a first side of a handling wafer, with a sidewall of the cavity forming a first angle greater than about 54.7 degrees with respect to a first side of the handling wafer at an opening of the cavity. Then, a bulk etch is performed on the first side of the handling wafer to modify the sidewall of the cavity to a second angle greater than about 90 degrees, with respect to the first side of the handling wafer at the opening of the cavity. Next, a second side of a second wafer is bonded to the first side of the handling wafer.
Abstract:
One or more methods of fabricating a microscale canopy wick structure having an array of individual wicks having one or more canopy members. Each method includes selectively etching a substrate to control the thickness of the canopy members and also control the width of a fluid flow channel between adjacent wicks in a manner that enhances the overall performance of the microscale canopy wick structure.
Abstract:
A system and method for manipulating the structural characteristics of a MEMS device include etching a plurality of holes into the surface of a MEMS device, wherein the plurality of holes comprise one or more geometric shapes determined to provide specific structural characteristics desired in the MEMS device.
Abstract:
A method of etching the whole width of a substrate to expose buried features is disclosed. The method includes etching a face of a substrate across its width to achieve substantially uniform removal of material; illuminating the etched face during the etch process; applying edge detection techniques to light reflected or scattered from the face to detect the appearances of buried features; and modifying the etch in response to the detection of the buried feature. An etching apparatus for etching substrate across its width to expose buried is also disclosed.

Abstract:
Es wird ein Verfahren zum plasmalosen Ätzen von Silizium mit dem Ätzgas ClF 3 (15) oder XeF 2 und dessen Verwendung vorgeschlagen. Dabei liegt das Silizium mit einem oder mehreren zu ätzenden Bereichen (20) als eine Schicht auf einem Substrat (1) oder als Substratmaterial selbst vor. Durch Einbringen von Germanium (30, 35) wird das Silizium in den Mischhalbleiter SiGe (40) überführt und durch Zuführung des Ätzgases ClF 3 (15) oder XeF 2 geätzt. Das Einbringen von Germanium (30, 35) und die Zuführung des Ätzgases ClF 3 (15) oder XeF 2 kann zeitlich parallel oder alternierend erfolgen. Insbesondere wird vorgeschlagen, das Einbringen von Germanium (30, 35) durch Implantation von Germanium-Ionen (35) in Silizium durchzuführen.

Abstract:
It is an object of the present invention to manufacture a micromachine having a plurality of structural bodies with different functions and to shorten the time required for sacrifice layer etching in a process of manufacturing the micromachine. Another object of the present invention is to prevent a structural layer from being attached to a substrate after the sacrifice layer etching. In other words, an object of the present invention is to provide an inexpensive and high-value-added micromachine by improving throughput and yield. The sacrifice layer etching is conducted in multiple steps. In the multiple steps of the sacrifice layer etching, a part of the sacrifice layer that does not overlap with the structural layer is removed by the earlier sacrifice layer etching and a part of the sacrifice layer that is under the structural layer is removed by the later sacrifice layer etching.
