Abstract:
Microstructure device forming methods, methods of forming a MEMS device, microstructure processing apparatuses and MEMS processing apparatuses are described. A first aspect provides a microstructure device forming method including: providing a substrate; etching the substrate within a process chamber to release a microstructure device feature coupled with the substrate; and monitoring a mass of monitored material within the process chamber during the etching to monitor the etching of the substrate.
Abstract:
A method for fabricating a nozzle of microchip-based electrospray device is disclosed. The method includes using a primary mask to accurately define the nozzle feature including the annulus and the through hole of the electrospray device. A secondary masking step is conducted to pattern the through channel (typical the photoresist would serve as the secondary mask), followed by the defining and etching of the primary mask containing the full nozzle feature. The secondary mask serves to selectively mask given areas of the primary mask for subsequent etching. The through hole feature of the secondary mask aligns over the already patterned primary mask through channel, except that the secondary mask contains a slightly larger through channel diameter. This serves to mask off the annulus, but allowing the silicon through channel to be exposed for etching.

PROBLEM TO BE SOLVED: To provide a fine structure formation method improving controllability of etching in fine machining using isotropic etching, and realizing uniform machining even in a large substrate. SOLUTION: In the fine structure formation method, an etching solution is used on a workpiece provided with a mask having a predetermined opening to carry out etching of the workpiece from the opening, and a recess is formed on a surface of the workpiece. Insoluble matter is provided by a reaction between a substance included in the workpiece and the etching solution, and etching is stopped by the insoluble matter accumulated on an exposed face of the workpiece.

PROBLEM TO BE SOLVED: To provide a method and a system for fluorinated xenon etching with improved efficiency. SOLUTION: A device and a method useful for manufacturing a MEMS device are provided. One mode of the disclosed device provides a substrate which is exposed to a solid state etchant and provided with a material enabled to be etched. Here, the substrate and the solid state etchant are arranged in an etching chamber. In a plurality of embodiments, the solid state etchant is moved to a position near the substrate. In the other embodiments, a variable barrier exists between the substrate and the solid state etchant, to be opened. The solid state etchant generates a vapor phase etchant suitable for etching the material enabled to be etched. In a plurality of desirable embodiments, the solid state etchant is solid 2 fluorinated xenon. The device and the method are advantageously used in executing release etching in manufacturing of an optical modulator. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract in simplified Chinese:本发明提供一种蚀刻方法,其能够以充分的速度将牺牲层从微细的蚀刻开口中除去,借此能够于形成包含较大中空部或构造复杂的空间部之构造体、乃至于高深宽比之构造体时,使其形状精度良好且表面状态不致劣化。其解决方法如下:将被处理物曝露于含有蚀刻反应物之处理流体,并使前述处理流体对被处理物保持流动状态(第4步骤 S4)。在该状态下,对被处理物的表面断续地照射光线,并断续地加热被处理物(第5步骤S5)。借此,一边将被处理物附近的前述处理流体断续地加热而使其膨胀、收缩,一边进行蚀刻。处理流体较佳使用含有蚀刻反应物的超临界状态之物质。
