In this paper, we present a novel laser direct writing system. Compared with conventional laser direct writing system, there are four key techniques in this system. They are illuminating system, leveling and focusing system, precise position work-stage system and diffractive focusing system. We introduce and analyze the four systems in this paper respectively. Through theoretic analysis and optical lithographic experiment, the results show that it provides a direction of higher resolution and lower cost optical lithographic technology. By proper design the structure of the whole system and the parameters of photon sieve, better resolution can be realized. |
