Abstract
Cutting elements for use with earth-boring tools include a cutting table having a base surface and a substrate having a support surface. An intermediate structure and an adhesion layer extend between the base surface of the cutting table and the support surface of the substrate. Earth-boring tools include such cutting elements. Methods for fabricating cutting elements for use with earth-boring tools include forming an intermediate structure on and extending from a support surface of a substrate and adhering a cutting table comprising a superabrasive material to the support surface of the substrate.
