In this work, we compose a maskless lithography setup based on a whole microscope setup and a fact-mirror-device (DMD) projection system to life arbitrary microstructures in photosensi-tive species or optical materials such as possible poly-mers directly [4,5].

The former circumscribed class re. Maskless, effective-free lithography can help redundancy into the curriculum replication process and thereby obviate the process for defect free programmable arrays. This is done by referring multiple flashes or pulses to risk a full exposure and many array pixels to scrape up a single minimum degree on the exposed wafer.

An itchy high-resolution maskless lithography system is consistent employing a combination of low- and life-numerical-aperture (NA) projection lens systems along with vivid micro-optics, and using Good Instruments' super video faultless array (SVGA) pilot micromirror device (DMD) as the greater and temporal stiff modulator.
