The present disclosure provides a secondary imaging optical lithography method and apparatus. The method includes: contacting a lithography mask plate with a flexible transparent transfer substrate closely, the flexible transparent transfer substrate comprising a first near-field imaging structure having a photosensitive layer; irradiating the photosensitive layer through the lithography mask plate with a first light source, so as to transfer a pattern of the lithography mask plate to the photosensitive layer; coating a device substrate for fabricating devices with a photoresist; contacting the flexible transparent transfer substrate with the photoresist-coated device substrate closely; irradiating the device substrate through the flexible transparent transfer substrate with a second light source, so as to transfer a pattern of the photosensitive layer to the photoresist of the device substrate; and developing the device substrate comprising an exposed photoresist, so as to obtain a device pattern conforming to the pattern of the lithography mask plate.

Embodiments of the disclosure generally relate to methods of forming gratings. The method includes depositing a resist material on a grating material disposed over a substrate, patterning the resist material into a resist layer, projecting a first ion beam to the first device area to form a first plurality of gratings, and projecting a second ion beam to the second device area to form a second plurality of gratings. Using a patterned resist layer allows for projecting an ion beam over a large area, which is often easier than focusing the ion beam in a specific area.

A method for producing metal decorations on a curved dial made of insulating material includes forming, by a method of the LIGA-UV type, a mould made of photosensitive resin and of galvanically depositing a layer of at least one metal from the conductive layer in order to form a block substantially reaching the upper surface of the photosensitive resin.

A method of forming a digital image on a flexographic printing plate comprising: attaching a portion of photopolymer to a dimensionally stable backing sheet; attaching a lead edge strip and a trail edge strip to said dimensionally stable backing sheet to form a flexographic printing plate; securing the flexographic printing plate comprising a portion of photopolymer to an imaging cylinder by securing the lead edge strip to a lead edge lock formation and securing said trail edge strip to a trail edge lock formation; imparting an image to said portion of photopolymer; and washing said photopolymer to remove unreacted photopolymer and drying said photopolymer to form a processed flexographic printing plate.

Systems and processes for making a flexo plate, and plates made thereby. Non-printing indicia defined by areas of resence and absence of polymer in the plate floor are readable downstream of the washing or other non-cured-polymer-removal step but do not print in the printing step. The non-printing indicia may define a repeating pattern of alphanumeric characters, non-text graphics, or a combination thereof.
