  • Publication number: 20240047266
    Abstract: A method of forming a protective layer utilized in a silicon remove process includes bonding a first wafer to a second wafer, wherein the first wafer comprises a first silicon substrate with a first device structure disposed thereon and the second wafer comprises a second silicon substrate with a second device structure disposed thereon. After that, a first trim process is performed to thin laterally an edge of the first wafer and an edge of the second device structure. After the first trim process, a protective layer is formed to cover a back side of the second silicon substrate. After forming the protective layer, a silicon remove process is performed to remove only the first silicon substrate.
