Zusammenfassung:A method includes forming feature for a first package component, and the forming the feature includes a planarization process to level a top surface of the feature. A silicon-containing dielectric layer is deposited over and contacting the feature, and as a surface feature of the first package component. A second package component is bonded to the silicon-containing dielectric layer through fusion bonding. The silicon-containing dielectric layer has a same thickness in both steps of the depositing and the fusion bonding.
