photolithographs

Example:Photomasks are used in photolithography to define the layout of circuits on semiconductor wafers.

Definition:Holes or transparent patterns that allow light to pass through in certain areas to project a desired pattern onto a substrate during photolithography.

Example:The old photoengravings provide a unique insight into the history of photography.

Definition:Images produced by photographic methods, especially by a process involving etching through a layer of light-sensitive material.
