Assignee: LIFELENS TECHNOLOGIES, LLC
Field: Surface technology, coating (Chemistry)
Classification: CPC A  B | IPC A  B

Claim 0:
1. An apparatus comprising:
a first support structure comprising an adhesive layer formed over a first carrier;
a film attached to the first support structure and comprising a first pattern of two or more vias formed at least partially therethrough, a first surface of the film being bonded to the adhesive layer of the first support structure;
wherein the film is stretchable in at least a first direction along the first surface; and
at least one functional layer formed over a second surface of the film opposite the first surface of the film, the at least one functional layer comprising one or more wrinkles, the one or more wrinkles having (i) an amplitude oriented substantially in a direction perpendicular to the second surface of the film and (ii) a wavelength propagating substantially along the first direction along the first surface, the one or more wrinkles enabling stretching of the at least one functional layer in the first direction along the first surface;
wherein the first carrier comprises a material having a first rigidity greater than a second rigidity of the film, the first carrier maintaining the first pattern of vias within a given threshold distortion following a given process conducted after the film is attached to the first support structure, the given threshold distortion being at least one of distortion less than 1% in locations of the two or more vias in the pattern of vias before and after the given process, distortion less than 10 micrometers (μm) in the first direction, and distortion in distance between centers of adjacent ones of the vias less than 10 μm.
