摘要:
A semiconductor device is formed of two or more dice of similar dimensions and bond pad arrangements, in which bond pads are located in fields along less than three edges of the active surface of each die. A first die is attached to a substrate and subsequent die or dice are attached in a vertical sequence atop the first die, each in an offset configuration from the next lower die to expose the bond pads thereof for conductive bonding to metallization of the substrate. The multiple chip device permits a plurality of dice to be stacked in a high-density low-profile device. A particularly useful application is the formation of stacked mass storage flash memory package.

A rerouting element for a semiconductor device that includes a dielectric film that carries conductive vias, conductive elements, and contact pads. The conductive vias are positioned at locations that correspond to the locations of bond pads of a semiconductor device with which the rerouting element is to be used. The conductive elements, which communicate with corresponding conductive vias, reroute the bond pad locations to corresponding contact pad locations adjacent to one peripheral edge or two adjacent peripheral edges of the rerouted semiconductor device. The rerouting element is particularly useful for rerouting centrally located bond pads of a semiconductor device, as well as for rerouting the peripheral locations of bond pads of a semiconductor device to one or two adjacent peripheral edges thereof. Methods for designing and using the rerouting element are also disclosed, as are semiconductor device assemblies including one or more rerouting elements.
摘要:
A rerouting element for a semiconductor device includes a substantially planar member that carries at least one contact location, at least one conductive, at least one rerouted bond pad. The contact location is positioned adjacent to a first periphered edge of the substantially planar member and at a location that corresponds to the location of a bond pad of a semiconductor device with which the rerouting element is to be used. The at least one conductive element, which communicates with the at least one contact location, reroutes the bond pad location of the semiconductor device to a corresponding rerouted bond pad location adjacent to a second one peripheral edge of the rerouted substantially planar member which is opposite the first periphered edge. In addition, assemblies including rerouting elements and methods for designing and using rerouting elements are disclosed.
摘要:
A method of bumping a wafer for facilitating bonding of bond wires to elevate the bond location above the passivation layer. The wafer is bumped by disposing the wafer in at least one electroless bath having a nickel-containing solution therein, wherein bumps having a nickel-containing material are formed simultaneously on the exposed bond pads to an elevation sufficient to prevent damage to a passivation layer surrounding the bond pads by contact of a wire bonding capillary. A gold or palladium cap may optionally be formed over the nickel-containing material of the bumps. A method of forming a semiconductor device assembly is also disclosed.
摘要:
A vertically mountable semiconductor device assembly including a semiconductor device and a mechanism for attaching the semiconductor device to a carrier substrate. The semiconductor device has each of its bond pads disposed proximate a single edge thereof. At least a portion of the semiconductor device may be exposed. An alignment device is attached to a carrier substrate. A mounting element on the vertically mountable semiconductor device package engages the alignment device to interconnect the semiconductor device and the alignment device. The alignment device may secure the vertically mountable semiconductor device package perpendicular relative to the carrier substrate. The distance between the bond pads and corresponding terminals on the carrier substrate is very small in order to reduce impedance. The vertically mountable semiconductor device package may also be readily user-upgradable.

A semiconductor chip package that includes discrete conductive leads in electrical contact with bond pads on a semiconductor chip. This chip/lead assembly is encapsulated within an encapsulating material and electrode bumps are formed through the encapsulating material to contact the conductive leads. The electrode bumps protrude from the encapsulating material for connection to an external circuit.

A multi-part lead frame die assembly is disclosed including a die bonded to a die paddle. A second lead frame including leads is superimposed and bonded onto the first lead frame. Also disclosed is a method for fabricating the multi-part lead frame assembly which utilizes equipment designed for single lead frame processing. If desired, the materials for the multi-part lead frame may be dissimilar.
摘要:
A method and apparatus for assembling and packaging semiconductor dice. The semiconductor dice or assemblies of stacked and electrically interconnected semiconductor dice are placed at mutually spaced locations with respect to a common plane and encapsulated in a dielectric material so that end portions of discrete conductive elements extending outwardly from each semiconductor die adjacent the common plane are exposed through an outer surface of the dielectric material. Redistribution lines are formed to extend from the exposed end portions of the discrete conductive elements to predetermined locations over the outer surface of the encapsulant which correspond with another interconnect outline and conductive bumps formed at the predetermined locations. Encapsulated semiconductor dice or die stacks may be severed from the encapsulant to form individual packages, or laterally spaced semiconductor dice electrically interconnected by redistribution lines may be maintained together as a group in a single package or module.
