The semiconductor device structure includes a substrate, a die and a stiffener. The substrate has an upper surface. The die is disposed on the upper surface of the substrate. The stiffener is disposed on the upper surface of the substrate and surrounds the die. The stiffener has a first upper surface adjacent to the die, a second upper surface far from the die and a lateral surface extending from the first upper surface to the second upper surface. A first distance between the first upper surface of the stiffener and the upper surface of the substrate is less than a second distance between the second upper surface of the stiffener and the upper surface of the substrate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device structure having stiffener with two or more contact points for heat dissipating element","description":"Semiconductor device structures and methods for manufacturing the same are provided.
