US Patent 11239182 Controlled induced warping of electronic substrates

An integrated circuit (IC) package incorporating controlled induced warping is disclosed. The IC package includes an electronic substrate having an active side upon which semiconducting dies and functional circuits have been lithographed or otherwise fabricated, leading to an inherent warping in the direction of the active side. One or more corrective layers may be deposited to the opposing, or inactive, side of the semiconducting die via thin film deposition (TFD) instrumentation and techniques in order to induce corrective warping of the electronic substrate back toward the horizontal (e.g., in the direction of the inactive side) to a desired degree.
