This paper presents a double-side-exposure scheme based on computer-numerical-controlled (CNC) UVLED lithography for fine 3-D microfabrication. The CNC UV-LED lithography manipulates the exposure angle of the UV light where the system comprises a switchable, movable UV-LED array as a light source, a motorized tilt-rotational sample holder, and a computer-control unit. The double-sided exposure scheme...
A droplet-born air-blowing method is an advanced method of the drawing lithography enables simple and fast fabrication, which does not require UV irradiation or moulding process. However, it has disadvantages such as low throughput in the formation of droplet array as it uses the dispenser to make droplets one by one. To increase the throughput while also simplifying the fabrication method, we suggest...
We propose a wafer-scale technique for nanostructure formation inside vertically oriented, through-membrane nano-pores. It uses 50 nm monocrystalline silicon pillars as a mold, embedded in a silicon nitride membrane formed in an innovative step. The proposed technique paves the way towards advanced functionalization of parallel oriented nano-pores for actuation, sensing, filtering/trapping purposes.
Degradation and delamination have been technically challenging for poly(3,4-ethylenedioxythiophene): polystyrene sulfonate) (PEDOT:PSS) thin-film processing due to environmental humidity. To overcome this problem, we introduced a one-step photolithographic method to both pattern and link a PEDOT:PSS film onto a PEG layer as a hybrid thin-film structure on a flexible substrate, which exhibited excellent...
In this study, we propose two devices that provide an easier and faster method to execute in-vitro fertilization (IVF) technique. The devices consist of a high quality sperm sorter and an oocytes zona-removal and incubation device to aid promoting the success rate and the efficiency of IVF technique. Comparing with the traditional IVF process, the high quality sperm sorter can gently sort out large...
