摘要： One aspect of the invention pertains to a semiconductor package having a die and a die attach pad with a plurality of spaced apart pedestals supported by a web. A die is mounted on the die attach pad such that the die is supported by at least a plurality of the pedestals. Selected edge regions of the die are arranged to overlie recessed regions of the die attach pad between adjacent pedestals. The die is electrically connected to at least some of the contact leads. An adhesive is arranged to secure the die to the die attach pad, with the thickness of the adhesive between the web of the die attach pad and the die being greater than the thickness of the adhesive between the die and the top surfaces of the pedestals that support the die. The die attach pad may have rounded peripheral corners between adjacent edge surfaces of the die attach pad. In another aspect of the invention, a method of packaging integrated circuits is described, wherein the resulting packages include at least some of the aforementioned leadframe structures.
