Electrohydrodynamic jet (E-Jet) is an approach to the fabrication of micro/nano-structures by the use of electrical forces. In this process, the liquid is subjected to electrical and mechanical forces to form a liquid jet, which is further disintegrated into droplets. The major advantage of the E-Jet technique is that the sizes of the jet formed can be at the nanoscale far smaller than the nozzle size, which can realize high printing resolution with less risk of nozzle blockage. The E-Jet technique, which mainly includes E-Jet deposition and E-Jet printing, has a wide range of applications in the fabrication of micro/nano-structures for micro/nano-electromechanical system devices. This technique is also considered a micro/nano-fabrication method with a great potential for commercial use. This study mainly reviews the E-Jet deposition/printing fundamentals, fabrication process, and applications.

In this paper, the state of art of ultrasonic-assisted machining technologies used for fabrication of micro/nano-textured surfaces is reviewed. Diamond machining is the most widely used method in industry for manufacturing precision parts. For fabrication of fine structures on surfaces, conventional diamond machining methods are competitive by considering the precision of structures, but have limitations at machinable structures and machining efficiency, which have been proved to be partly solved by the integration of ultrasonic vibration motion. In this paper, existing ultrasonic-assisted machining methods for fabricating fine surface structures are reviewed and classified, and a rotary ultrasonic texturing (RUT) technology is mainly introduced by presenting the construction of vibration spindles, the texturing principles, and the applications of textured surfaces. Some new ideas and experimental results are presented. Finally, the challenges in using the RUT method to fabricate micro/nano-textured surfaces are discussed with respect to texturing strategies, machinable structures, and tool wear.

Device miniaturization is an emerging advanced technology in the 21st century. The miniaturization of devices in different fields requires production of micro- and nano-scale components. The features of these components range from the sub-micron to a few hundred microns with high tolerance to many engineering materials. These fields mainly include optics, electronics, medicine, bio-technology, communications, and avionics. This paper reviewed the recent advances in micro- and nano-machining technologies, including micro-cutting, micro-electrical-discharge machining, laser micro-machining, and focused ion beam machining. The four machining technologies were also compared in terms of machining efficiency, workpiece materials being machined, minimum feature size, maximum aspect ratio, and surface finish.

针对纳米器件中的典型几何特征,制备了3种纳米结构,采用扫描电子显微镜(SEM)、原子力显微镜(AFM)等测量工具对所制备的纳米样板进行了测量、分析和表征。提出转换薄膜厚度为线宽的公称值、基于多层薄膜淀积技术制备纳米宽度结构的方法,制备出了具有名义线宽尺寸分别为20 nm、25 nm、35 nm的纳米栅线结构。用离线的图像分析算法对所制备的纳米线宽样板的线边缘粗糙度/线宽粗糙度(LER/LWR)以及栅线线宽的一致性进行了评估。实验表明所制备纳米线宽样板的栅线具有较好的一致性,LER/LWR值小,且具有垂直的侧壁。采用电子束直写技术(EBL)和感应耦合等离子体刻蚀(ICP)制备了名义高度为220 nm的硅台阶样板。实验表明刻蚀后栅线边缘LER/LWR的高频成分减少,相关长度变长,均方根偏差值(σ)增大。采用聚焦离子束(FIB)制备了纳米单台阶和多台阶结构,并对Z方向的尺度与加工能量之间的关系进行了分析。
