Patent ID: 8796112

Claim:
A method of forming a three-dimensional electronic device, comprising: forming at least one electronic device on a two-dimensional, flexible substrate, the electronic device being formed according to a three-dimensional structure; cutting the two-dimensional, flexible substrate, the cuts being located to allow the two-dimensional substrate to be shaped, the cuts having at least one stress relief feature and that two cut lines meet to form an apex, cutting the substrate further comprising at least one of: cutting a circle centered at the apex, the circle forming the stress relief feature, altering a path of at least one of the cuts to form a cubic portion of a wedge shape, and extending one of the cut lines past the apex forming an extended cut, the extended cut forming the stress relief feature; and shaping the two-dimensional, flexible substrate to form the three-dimensional structure, the stress relief features arranged to alleviate stress in the three-dimensional structure.
