This abstract first appeared for US patent application 18689541 titled 'FOLDABLE SUBSTRATES AND METHODS OF MAKING
Original Abstract Submitted
Foldable substrates comprise a first portion, a second portion, and a central portion positioned therebetween. The central portion comprises a first transition region comprising a first transition width and a first transition surface area extending between a first surface area of the first portion and a first central surface area of the central portion with a first average angle. In aspects, the first average angle is from about 167° to about 179°. In aspects, the first transition width is from about 150 micrometers to about 700 micrometers. Methods comprise disposing an etch mask over the first major surface of the foldable substrate before etching the foldable substrate. In aspects, the etch mask comprises a first polymer layer positioned between a first barrier layer and the first major surface. In aspects, the etch mask comprises a positive photoresist.
