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.

Methods for forming an edge contact on a die and edge contact structures are described. The edge contacts on the die do not increase the height of the die. The edge contacts are positioned on the periphery of a die. The edge contacts are positioned in the saw streets. Each edge contact is connected to one bond pad of each die adjacent the saw street. The edge contact is divided into contacts for each adjacent die when the dies are separated. In an embodiment, a recess is formed in the saw street. In an embodiment, the recess is formed by scribing the saw street with a mechanical cutter. The recess is patterned and contact material is deposited to form the edge contacts.

Apparatus and method for packaging circuits

An apparatus comprises an integrated circuit die including a main body having a top layer, a bottom layer, and a peripheral edge surface extending between the top layer and the bottom layer. The integrated circuit die also includes a bond pad on the main body, an edge contact at the peripheral edge surface and a line connecting the bond pad to the edge contact. The edge contact includes a bottom surface that substantially in the same plane as a surface of an encapsulant encasing the die. Additional apparatus, systems, and methods are disclosed.

Packaged microelectronic components

Methods of forming a semiconductor assembly are described which include a leadframe with leads having offset portions exposed at an outer surface of a material package to form a grid array. An electrically conductive compound, such as solder, may be disposed or formed on the exposed lead portions to form a grid array such as a ball grid array ('BGA') or other similar array-type structure of dielectric conductive elements. The leads may have inner bond ends including a contact pad thermocompressively bonded to a bond pad of the semiconductor chip to enable electrical communication therewith and a lead section with increased flexibility to improve the thermocompressive bond. The inner bond ends may also be wirebonded to the bond pads.

Methods for making semiconductor packages with leadframe grid arrays

A semiconductor assembly includes a leadframe with leads having offset portions exposed at an outer surface of a material package to form a grid array. An electrically conductive compound, such as solder, may be disposed or formed on the exposed lead portions to form a grid array such as a ball grid array (&ldquo;BGA&rdquo;) or other similar array-type structure of dielectric conductive elements. The leads may have inner bond ends including a contact pad thermocompressively bonded to a bond pad of the semiconductor chip to enable electrical communication therewith and a lead section with increased flexibility to improve the thermocompressive bond. The inner bond ends may also be wirebonded to the bond pads. Components for and methods of forming semiconductor assemblies are included.
