Recently, there has been much focus on the controlled alignment and patterning process of nanowires for nanoelectronic devices. A simple and effective method for patterning of highly aligned nanowires using a microcontact printing technique is demonstrated. In this method, nanowires are first directionally aligned by contact printing, following which line and space micropatterns of nanowire arrays are accomplished by microcontact printing with a micro patterned NOA mold.

Recent a few decades, the microtechnology has been progressed so rapidly and applied in diverse areas. Especially, this technology was focused on the field of biotechnology and medicine because of its size and simple fabrication process. In this paper, the current status of microtechnology is briefly introduced from the aspect of material, process and device and the application of this technology in biotechnology and medicine is also described. The microtechnology will be more broadly applied in future in the biotechnology and medicine area and the biomedical engineer should have continuous interests in this technology.

Transferring patterns from mold to PDMS stamp is very useful technology in micro-fabrication, complex and three-dimensional structures. First experimentation, mold's patterns wens transferred to PDMS stamp. Comparing with PDMS stamp and Mold, patterns were transferred about 97.9%. Second experimentation, PDMS stamps were made several times by only one mold, scale and distance of transferred patterns were uniform about 89.3%. We proved that transferring patterns from mold to PDMS stamp is accurate. The uniformity of stamps is the same after mold was used several times. Transferring patterns from mold to PDMS stamp has uniformity and accuracy, it will be useful technology.
