Package for solid image pickup element and solid image pickup device
Abstract:
In a package including a base fixed with a solid image pickup element, a side wall rising up along the periphery of the base, and internal terminals arranged on a step of the side wall, a plurality of recesses are formed at certain intervals in a lower part of the step to prevent bleeding of an adhesive fixing the solid image pickup element from creeping up over the internal terminals. When the adhesive and bleeding thereof spread around the solid image pickup element during die bonding, they flow into the recesses, making even fast-flowing bleeding hardly creep up an inner surface of the side wall including the step, and enabling prevention of the adhesive from adhering to the internal terminal. Strength, questioned by the presence of the recesses upon wire bonding, can be secured by residual parts between the recesses, and defective wire bonding is less likely to occur.
