Abstract
An embodiment is a structure. The structure comprises a substrate, a chip, and a reinforcement component. The substrate has a first surface, and the first surface comprises depressions. The chip is over and attached to the first surface of the substrate. The reinforcement component is over a first area of the first surface of the substrate. The first area is not under the chip. The reinforcement component has a portion disposed in at least some of the depressions in the first area.
Claims18
A structure comprising:
- a substrate having a first surface, separate depressions extending into the substrate from the first surface of the substrate;
- a chip over and attached to the first surface of the substrate;
- and
- a reinforcement component over a first area of the first surface of the substrate, the first area not being under the chip, the reinforcement component having a portion disposed in at least some of the depressions in the first area, wherein the reinforcement component comprises a lid and an adhesive, the lid having a first portion over the chip and a second portion over the first area of the first surface of the substrate, the adhesive being between the second portion of the lid and the first surface of the substrate, the adhesive being disposed in the at least some of the depressions in the first area.
