The present disclosure, in some embodiments, relates to an integrated chip structure. The integrated chip structure includes a bump structure disposed on a first substrate and a molding compound in physical contact with the bump structure. The bump structure protrudes from the molding compound. A conductive region is on a second substrate and contacts the bump structure. A no-flow underfill (NUF) material is vertically between the molding compound and the second substrate and laterally surrounds the bump structure. The NUF material is separated from the molding compound.
