    Abstract : Light is the primary source of energy on our planet and has been a significant driver in the evolution of human society and technology. Light finds applications in two-dimensional (2D) photolithography and three-dimensional (3D) printing, where a pattern is transferred to a material of interest by ultraviolet (UV) light exposure, and in laser scribing and cutting, where high power lasers are used to pattern the surface of objects or cut through the bulk of the material of interest.

    Abstract : A conventional logic synthesis flow is composed of three separate phases: technologyindependent optimization, technology mapping, and technology dependentoptimization. A fundamental problem with such a three-phased approach is thatthe global logic structure is decided during the first phase without any knowledge ofthe actual technology parameters considered during later phases.
