Based on previous theoretical and experimental results on the electrochemical etching of silicon in HF‐based aqueous electrolytes, it is shown for the first time that silicon microstructures of various shapes and silicon microsystems of high complexity can be effectively fabricated in any research lab with sub‐micrometer accuracy and high aspect ratio values (about 100). This is well beyond any up‐to‐date wet or dry microstructuring approach and is achieved using a wet etching, low‐cost technology: silicon electrochemical micromachining (ECM). Dynamic control of the etching anisotropy (from 1 to 0) as the electrochemical etching progresses allows the silicon dissolution to be switched in real‐time from the anisotropic to the isotropic regime and enables advanced silicon microstructuring to be achieved through the use of high‐aspect‐ratio functional and sacrificial structures, the former being functional to the microsystem operation and the latter being sacrificed for accurate microsystem fabrication. World‐wide dissemination of the ECM technology for silicon microstructuring is envisaged in the near future, due to its low cost and high flexibility, with high‐potential impact on, though not limited to, the broad field of microelectronics and microfabrication. 相似文献

微电子机械和纳米技术的研究覆盖了亚微米到纳米尺寸的特征范围,它主要依靠光刻和图形转换设备和工艺获得,但又不仅限于半导体加工范畴。光学光刻设备、感应耦合等离子体刻蚀,金属的溅射涂覆,金属的等离子体增强CVD、介质隔离、掺杂注入、粒子柬微写设备和X射线源可以看作MEMS和纳米技术的机械加工手段,其各有独具的优势限制。现正被用于定制的MEMS器件到真空微电子器件和新颖的纳米工具的研究与开发应用。抗蚀剂喷涂技术为复杂形貌的MEMS器件光刻提供了高均匀性作图的厚胶基础。对于MEMS技术进入产业化的主要技术瓶颈-MEMS封装技术研究与开发已成为当今世界各国关注的热点。同时,对于MEMS器件的测试技术的研究,目前在国际上也引起了高度的重视。 相似文献

We present a new type of silicon micro‐probe card using a three‐dimensional probe beam of the cantilever type. It was fabricated using KOH and dry etching, a porous silicon micromachining technique, and an Au electroplating process. The cantilever‐type probe beam had a thickness of 5 μm, a width of 50 µm, and a length of 800 μm. The probe beam for pad contact was formed by the thermal expansion coefficient difference between the films. The maximum height of the curled probe beam was 170 µm, and an annealing process was performed for 20 min at 500°C. The contact resistance of the newly fabricated probe card was less than 2 Ω, and its lifetime was more than 20,000 turns. 相似文献
