Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 16:
17. A method of manufacturing a semiconductor structure, comprising:
providing a substrate;
forming a first conductive pillar, a second conductive pillar and a third conductive pillar over the substrate, the first conductive pillar comprising a first height, the second conductive pillar comprising a second height, and the third conductive pillar comprising a third height different from the first height and the second height;
disposing a first die over the first conductive pillar, the first die comprising a first surface distal to the substrate;
disposing a second die over the second conductive pillar, the second die comprising a second surface distal to the substrate;
disposing a third die over the third conductive pillar, the third die comprising a third surface distal to the substrate;
disposing an underfill material encapsulating the first conductive pillar, the second conductive pillar, and the third conductive pillar;
disposing a molding over the substrate, the molding comprising a top surface; and
disposing a heat dissipation means over the molding,, wherein the first surface of the first die, the second surface of the second die, the third surface of the third die and the top surface of the molding are at substantially same level, and, wherein a distance between the first conductive pillar and the heat dissipation means is greater than a distance between the second conductive pillar and the heat dissipation means.
