Patent number: 11990431Abstract: The present disclosure discloses a semiconductor structure having an insulating layer disposed on a wafer active surface of a semiconductor wafer for covering the wafer active surface. The insulating layer may be a protective layer in some embodiments and a cover layer in other embodiments. The insulating layer has via openings to expose contact pads for leading out electrical connections. In particular, the via openings are formed by a multi-step etching process (such as a two-step etching process) without damaging the contact pads. The two-step etching process includes a first laser etching process using normal pulse (P) and normal energy to form partial via openings in the cover layer. The second etching process includes either a laser etching process using low P and low E or a plasma etching process. The second etching process avoids damaging the contact pads.Type: GrantFiled: November 17, 2021Date of Patent: May 21, 2024Assignee: PEP INNOVATION PTE. LTD.Inventor: Hwee Seng Chew

Patent number: 11990353Abstract: A wafer-level buffer layer is disclosed. The wafer-level buffer layer is configured to prevent cracking and chipping the back-end-of-line (BEOL) dielectric during wafer singulation process. The wafer-level buffer layer is a composite wafer-level buffer layer with a vibration damping agent. The vibration damping agent includes a polymer-based base layer with fillers. The damping agent absorbs or dampens the vibration of the saw blade during dicing to prevent cracking and chipping of the BEOL dielectric.Type: GrantFiled: July 15, 2021Date of Patent: May 21, 2024Assignee: PEP INNOVATION PTE. LTD.Inventors: Hwee Seng Jimmy Chew, Senthil Kumar Munirathinam
