Abstract: The present invention relates to a chip having a metal pillar structure. The chip includes a chip body, at least one chip pad, a first passivation layer, an under ball metal layer and at least one metal pillar structure. The chip body has an active surface. The chip pad is disposed on the active surface. The first passivation layer is disposed on the active surface, and has at least one first opening so as to expose part of the chip pad.

Abstract: This invention is directed to a food container comprising a lid and a base. The lid and base form three seals, including a locking seal, to prevent the leakage or spoilage of food during transport or temporary storage. Blades on the lid sealing edge and blades on the base sealing edge strengthen said edges, and further reinforce the seals formed between the lid and base. The lid and base, separately or when assembled, are stably stackable requiring a minimal amount of storage space.
