摘要:
A semiconductor device includes a carrier with an interface layer applied over the carrier. The interface layer can include non-conductive paste or non-conductive film. A plurality of semiconductor die is mounted to the carrier and interface layer by pressing the semiconductor die to the carrier and interface layer for one second or less, and simultaneously thermal compression bonding multiple semiconductor die to the carrier and interface layer for 5-10 seconds. By pressing the semiconductor die to the interface layer for a short period of time and then simultaneously thermal compression bonding multiple semiconductor die to the interface layer for a second longer period of time, the overall throughput of die bonding increases to process more die per unit of time. An encapsulant is deposited over the semiconductor die. The carrier is removed and interconnect structure is formed over the semiconductor die and encapsulant.

摘要:
A semiconductor device includes a substrate, a first recessed conductive layer embedded and recessed into a first surface of the substrate, and a first raised conductive layer disposed above the first surface. A first vertical offset exists between an upper surface of the first recessed conductive layer and an upper surface of the first raised conductive layer. The device includes a second recessed conductive layer embedded and recessed into a second surface of the substrate. The second surface of the substrate is opposite the first surface. The device includes a second raised conductive layer disposed beneath the second surface and an interconnect structure disposed on the first recessed and raised conductive layers and the second recessed and raised conductive layers. A second vertical offset exists between a lower surface of the second recessed conductive layer and a lower surface of the second recessed conductive layer.
摘要:
A semiconductor device has a first substrate and first conductive pillars formed over the first substrate. Second conductive pillars are formed over the first substrate alternating with the first conductive pillars. The second conductive pillars are vertically offset with respect to the first conductive pillars. First BOT interconnect sites are formed over a second substrate. Second BOT interconnect sites are formed over the second substrate alternating with the first interconnect sites. The second interconnect sites are vertically offset with respect to the first interconnect sites. The first substrate is mounted to the second substrate such that the first conductive pillars are aligned with and electrically connected to the first interconnect sites and the second conductive pillars are aligned with and electrically connected to the second interconnect sites. An underfill material is deposited between the first and second substrates. The first substrate can be a flipchip type semiconductor device.
