  • Publication number: 20220037274
    Abstract: The semiconductor package has a metal layer, a first dielectric layer formed on a metal layer, and an opening formed through the first dielectric layer to expose a part of the metal layer. The bump structure has an under bump metallurgy (hereinafter UBM), a first buffer layer and a metal bump. The UBM is formed on the first part of the metal layer, a sidewall of the opening and a top surface of the first dielectric layer. The first buffer layer is formed between a part of the UBM corresponding to the top surface of the first dielectric layer and the top surface of the first dielectric layer. The metal bump is formed on the UBM. Therefore, the first buffer layer effectively absorbs a thermal stress to avoid cracks generated in the bump structure after the bonding step.
