Using excimer laser to manufacture polymer materials can get more ideal biochips. The reciprocal mechanism of excimer ablation and the PMMA material were studied by using the KrF excimer with wavelength of 248 nm. On the surface of PMMA,pores and microchannels were fabricated and the rules of technics parameters of excimer laser and machining quality were disscussed. The excimer laser ablation is suitable for fabrication of biochip and its process is simple.
