SEMICONDUCTOR PACKAGE USING HYBRID-TYPE ADHESIVE
A semiconductor package includes a first die, a second die, and a hybrid-type adhesive. The second die is stacked on the first die through the hybrid-type adhesive. The hybrid-type adhesive includes a conductive adhesive and a non-conductive adhesive. The conductive adhesive is disposed between the non-conductive adhesive and the first die. The non-conductive adhesive is disposed between the conductive adhesive and the second die.
Package Structure and Method and Equipment for Forming the Same
An apparatus for manufacturing packaged semiconductor devices includes a lower plate having package platforms and clamp guide pins to align an upper plate with the lower plate, and a boat tray having windows configured to receive package devices, and a plurality of upper plates configured to be aligned to respective windows and respective package platforms. Clamping force can be applied by fasteners configured to generate a downward force upon the upper plate. Package devices on the platforms are thus subjected to a clamping force. Load cells measure the clamping force so adjustments can be made.

A method utilized at a sintered metal layer bonding a semiconductor element and a support substrate together suppresses cracks appearing in the sintered metal layer, and damage to the semiconductor element. A semiconductor device includes a support substrate, a semiconductor element, and a sintered metal layer bonding the support substrate and the semiconductor element. The sintered metal layer has a low porosity region disposed inward of an outer edge of the semiconductor element with the sintered metal layer bonded to the semiconductor element. The region is lower in porosity than the remaining sintered metal layer, and is formed as a wall-shaped structural body having an elongated string and extending from an upper surface to a lower surface of the sintered metal layer. The low porosity region is disposed to surround a region immediately below a center of the semiconductor element along the outer edge of the semiconductor element.

Electromagnetic interference shield created on package using high throughput additive manufacturing
A device package and a method of forming the device package are described. The device package includes a substrate having a ground plane and dies disposed on the substrate. The dies are electrically coupled to the substrate with solder balls or bumps surrounded by an underfill layer. The device package has a mold layer disposed over and around the dies, the underfill layer, and the substrate. The device package further includes an additively manufactured electromagnetic interference (EMI) shield layer disposed on an outer surface of the mold layer. The additively manufactured EMI shield layer is electrically coupled to the ground plane of the substrate. The outer surface of the mold layer may include a topmost surface and one or more sidewalls that are covered with the additively manufactured EMI shield layer. The additively manufactured EMI shield may include a first and second additively manufactured EMI shield layers and an additively manufactured EMI shield frame.
Nanowire bonding interconnect for fine-pitch microelectronics
A nanowire bonding interconnect for fine-pitch microelectronics is provided. Vertical nanowires created on conductive pads provide a debris-tolerant bonding layer for making direct metal bonds between opposing pads or vias. Nanowires may be grown from a nanoporous medium with a height between 200-1000 nanometers and a height-to-diameter aspect ratio that enables the nanowires to partially collapse against the opposing conductive pads, creating contact pressure for nanowires to direct-bond to opposing pads. Nanowires may have diameters less than 200 nanometers and spacing less than 1 μm from each other to enable contact or direct-bonding between pads and vias with diameters under 5 μm at very fine pitch. The nanowire bonding interconnects may be used with or without tinning, solders, or adhesives. A nanowire forming technique creates a nanoporous layer on conductive pads, creates nanowires within pores of the nanoporous layer, and removes at least part of the nanoporous layer to reveal a layer of nanowires less than 1 μm in height for direct bonding.
