Patent number: 8637973Abstract: A microelectronic component package includes a plurality of electrical leads which are coupled to a microelectronic component and which have exposed lengths extending outwardly beyond a peripheral edge of an encapsulant. A plurality of terminals may be positioned proximate a terminal face of the encapsulant and these terminals may be electrically coupled to the same leads. This can facilitate connection of the microelectronic component to a substrate using the leads as a conventional leaded package. The terminals, however, can facilitate stacking of the leaded package with one or more additional microelectronic components, e.g., a BGA package.Type: GrantFiled: March 27, 2007Date of Patent: January 28, 2014Assignee: Micron Technology, Inc.Inventors: Eng Meow Koon, Low Siu Waf, Chan Min Yu, Chia Yong Poo, Ser Bok Leng, Zhou Wei
