WebNegative photoresist responds to light in opposite manner such that the unexposed regions of the resist will dissolve in the developer solution, while the exposed regions remain behind [1]. 1.2. TYPES OF PHOTORESISTS Currently three different types of photoresists are commonly used, namely liquid photoresist, dry film, and SU-8 photoepoxy. WebOver the past decade, researchers have shattered the traditional view of the diffraction limit. Using new techniques, they have obtained resolution far smaller than the wavelength of light excitation or emission. Similar concepts are now being applied to photolithography, making it possible to create nanoscale features in a photoresist using visible or near-infrared light.
