WebTNIL (sometimes called hot embossing lithography (HEL)) was the first reported NIL technique described by Chou et al. in 1995. 17,23,24 The basic principles of TNIL have origins in HEL (e.g., LIGA) with the difference being that the process is performed at the sub-100 nm scale. The process of TNIL requires a hard mold, with predetermined … WebA lithography (more formally known as ‘photolithography’) system is essentially a projection system. Light is projected through a blueprint of the pattern that will be printed (known as a ‘mask’ or ‘reticle’). With the pattern encoded in the light, the system’s optics shrink and focus the pattern onto a photosensitive silicon wafer. god took a rib from adam and created eve kjv
