The first redistribution line is in the first dielectric layer. The method further includes performing a planarization on the first dielectric layer to level a top surface of the first dielectric layer, forming a metal post over and electrically coupling to the first redistribution line, and encapsulating the metal post in an encapsulating material. The encapsulating material contacts a top surface of the planarized top surface of the first dielectric layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Planarizing RDLS in RDL-first processes through CMP process","description":"A method includes forming a buffer dielectric layer over a carrier, and forming a first dielectric layer and a first redistribution line over the buffer dielectric layer.
