NANOIMPRINTING BY USING SOFT MOLD AND RESIST SPREADING

A flexible mold has a mold body having a nanoimprinting microstructure and is gradually thickened from its periphery to the middle. Also, a resist spreading nanoimprinting method that integrates a soft mold into a dovetailed meal ring and then deforms it to form a point contact with a substrate before an imprinting process is followed and then convert a loading force into a specific distributed contact pressure for driving the resist flow by using an elastomer cushion pad with a pre-designed convex surface.

METHOD FOR TRANSFERRING AN EMBOSSED STRUCTURE TO THE SURFACE OF A COATING AND COMPOUND STRUCTURE CONTAINING SAID COATING

10875069 · 2020-12-29 · ·

A device and method enabling industrial continuous pressing, called extrusion of plastically/thermally mouldable substances such as metal, composite metal, plastic, composite or rubber, which is pressed to the profile by a process including a tool fixed member partially predefining the profile shape/cross-section before the profile is finally defined to a cross-section when the material passes rotating dies, which through contact with each other, cancel out main radial forces and the position of which may vary relative to other bearing surfaces or rotary bearing surfaces of the tool with which they define the final shape of the profile. The device and method enable the extrusion of pattern on the inside of hollow profiles and the extrusion of multiple profiles in one tool, because 80-98% of radial bearing forces are eliminated, allowing the installation of rotary dies where not previously possible, and almost unlimited opportunities in increased profile width.
