Stack packages
A stack package is provided. The stack package includes a package substrate on which a first bond finger and a second bond finger are spaced apart from each other, and a second semiconductor die stacked over a first semiconductor die. A first connector connects the first semiconductor die to the first bond finger. A second connector connects the second semiconductor die to the second bond finger and extends to have substantially the same length as the first connector.
