Abstract
An integrated circuit package, a die carrier, and a die are provided. The die carrier includes at least one die pad and a plurality of leads. The at least one die pad is suitable for carrying the die. The leads surround the at least one die pad. The leads are disposed on four sides of the die carrier. A length of a long side among the four sides is twice or more a length of a short side among the four sides. The die carrier is suitable for a QFN package or a QFP package.
