Abstract

Space transformers, planarization layers for space transformers, methods of fabricating space transformers, and methods of planarizing space transformers are disclosed herein. In one embodiment, the space transformers include a space transformer assembly including a first rigid space transformer layer, a second rigid space transformer layer, and an attachment layer that extends between the first rigid space transformer layer and the second rigid space transformer layer. In another embodiment, the space transformers include a space transformer body and a flex cable assembly. The planarization layer includes an interposer, a resilient dielectric layer, a planarized rigid dielectric layer, a plurality of holes, and an electrically conductive paste extending within the plurality of holes. In one embodiment, the methods include methods of fabricating the space transformer assembly. In another embodiment, the methods include methods of planarizing a space transformer.
