基于电子束光刻的LIGA技术研究 总被引:3,自引:2,他引:1
提出了基于电子束的LIGA(Lithographie,Galvanoformung,Abformung)技术新概念。根据Grune公式就电子束能量对抗蚀剂刻蚀深度的影响进行了理论分析,并在SDS—2电子束曝光机上分别采用5keV、10keV、15keV、20keV、25keV、30keV等能量的电子束对国产胶苏州2号进行了曝光实验,得出了能量/刻蚀深度关系曲线。用5keV、30keV两种能量的电子束,通过改变曝光时间进行了曝光剂量对刻蚀深度的影响实验,得出了曝光剂量—刻蚀深度关系曲线。实验结果表明,增大电子束能量或增强曝光剂量,就可以增大刻蚀深度,证明了基于电子束光刻的LIGA技术不但是可行的,而且更易于加工各种带曲率的微器件。 相似文献

We fabricated 9-30 nm half-pitch nested Ls and 13-15 nm half-pitch dot arrays, using 2 keV electron-beam lithography with hydrogen silsesquioxane (HSQ) as the resist. All structures with 15 nm half-pitch and above were fully resolved. We observed that the 9 and 10-nm half-pitch nested Ls and the 13-nm-half-pitch dot array contained some resist residues. We obtained good agreement between experimental and Monte-Carlo-simulated point-spread functions at energies of 1.5, 2, and 3 keV. The long-range proximity effect was minimal, as indicated by simulated and patterned 30 nm holes in negative-tone resist. 相似文献

A proximity-effect correction method for VLSI patterns has been developed. In this method, a dose ratio has been introduced as a control parameter for the negative- resist thickness after development, in addition to the proximity parameters.A new technique has been used to obtain the proximity parameters. By using the dose ratio and the proximity parameters, both the exposure dose and the size of the irradiated shape are easily determined.A pattern accuracy of ±0.1 μm and a uniform resist of the desired thickness were obtained. The computation time is proportional to 1.2 power of pattern density, and is 100 seconds on a 1.5-MIPS computer when correcting for 104 shapes in a pattern whose pattern density is 104. 相似文献

Ultraviolet-nanoimprint lithography (UV-NIL) is a promising cost-effective method for defining nanoscale structures at room temperature and low pressure. To apply a large-area stamp to a high throughput step-and-repeat process at atmospheric conditions, we proposed a new UV-NIL process that uses an elementwise patterned stamp (EPS), which consists of elements separated by channels, and additive gas pressurization. The proposed UV-NIL process required just four imprints to press an 8-in. wafer. EPS features measuring 50-80 nm were successfully transferred onto the wafers. The experiments demonstrated that a 5 × 5-in.2 EPS could be used with a step-and-repeat UV-NIL process to imprint 8-in. wafers under atmospheric conditions. 相似文献

We have designed and fabricated a low-energy electron-beam lithography system based on a single column module (SCM) microcolumn. From the observed characteristics of the polymethyl methacrylate (PMMA) resist, the optimum conditions for the low-energy e-beam lithography have been determined. Fine line patterns on PMMA with line width less than 60 nm were obtained under optimized lithographic conditions. For the first time an aluminum photo-mask for optical lithography was created utilizing microcolumn lithography. Our results show that low-energy lithography systems have the potential to be used in high quality photo-mask fabrication processes. 相似文献
