Abstract
Methods for forming substantially chip scale packages and the resulting structures. The methods comprise applying an adhesive on an active surface of a semiconductor chip to form a patterned adhesive layer on a portion of the active surface. A leadframe having leads with inner lead ends and outer lead ends is provided. The inner lead ends of the leads are aligned proximate to the adhesive-free area and the leads are attached to the adhesive layer on the active surface of the semiconductor chip. The outer lead ends are oriented to form a footprint which is not substantially larger than the dimensions of the semiconductor chip.
