As to metal halide torch with gallium iodide is special rise 403nm and 417nm wave crest, and the highest wave crest 417nm has conspicuousness and good effect to exposal Diazo material.
The rudiments of microneedle actuator have been developed, which is mainly made of SU 8 photoresist, and its 3D construction is fabricated by multistep exposal and electroforming metal.
Uniformity of the photoresist film, adhesiveness between underlay and glue film, exposal and develop condition of high thickness difference are all solved in the thesis.
