The redistribution layer is disposed on the semiconductor die, and being electrically connected to the semiconductor die. The plurality of conductive balls is disposed between the redistribution layer and the circuit substrate. The semiconductor die is electrically connected to the circuit substrate through the conductive balls. Each of the conductive balls has a ball foot with a first width D1, a ball head with a third width D3 and a ball waist with a second width D2 located between the ball foot and the ball head. The ball foot is connected to the redistribution layer, the ball head is connected to the circuit substrate, and the ball waist is the narrowest portion of each of the conductive balls."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Package structure having a plurality of conductive balls with narrow width for ball waist","description":"A package structure including a circuit substrate, a semiconductor die, a redistribution layer, a plurality of conductive balls and a circuit substrate is provided.
