Lithography pitch
Web1 okt. 2015 · A minimum of 3 um lithography RDLs at 40 um pitch was achieved using chemical mechanical polishing (CMP), photo-vias, and a dry, single-sided semi-additive process flow. Glass interposers have been proposed and are being developed as a superior alternative to silicon and organic interposers [ 6 ]– [ 8 ]. WebThe fundamental limit of optical lithography is not determined by the optical system alone but rather is an overall contributions from the optics, resist, develop and …

http://www.lithoguru.com/scientist/CHE323/Lecture57.pdf WebNanoimprinting lithography (NIL) is a promising technology to produce sub-50nm half-pitch features on silicon- and/or quartz-based substrates. It is well-known as the next generation lithography. Especially, the UV-nanoimprint lithography technology has advantages of the simple process, low cost, high replication fidelity and relatively high throughput.
