Abstract: Disclosed are embodiments of a substrate for an integrated circuit (IC) device. The substrate includes a core comprised of two or more discrete glass layers that have been bonded together. A separate bonding layer may be disposed between adjacent glass layers to couple these layers together. The substrate may also include build-up structures on opposing sides of the multi-layer glass core, or perhaps on one side of the core. Electrically conductive terminals may be formed on both sides of the substrate, and an IC die may be coupled with the terminals on one side of the substrate. The terminals on the opposing side may be coupled with a next-level component, such as a circuit board. One or more conductors extend through the multi-layer glass core, and one or more of the conductors may be electrically coupled with the build-up structures disposed over the core. Other embodiments are described and claimed.

Abstract: Embodiments of the present disclosure may generally relate to systems, apparatus, and/or processes to form volumes of oxide within a fin, such as a Si fin. In embodiments, this may be accomplished by applying a catalytic oxidant material on a side of a fin and then annealing to form a volume of oxide. In embodiments, this may be accomplished by using a plasma implant technique or a beam-line implant technique to introduce oxygen ions into an area of the fin and then annealing to form a volume of oxide. Processes described here may be used manufacture a transistor, a stacked transistor, or a three-dimensional (3-D) monolithic stacked transistor.

Abstract: Transistor structures with gate material self-aligned to underlying channel material. A channel mask material employed for patterning channel material is retained during selective formation of a second mask material upon exposed surfaces of gate material. The channel mask material is then thinned to expose a sidewall of adjacent gate material. The exposed gate material sidewall is laterally recessed to expand an opening beyond an edge of underlying channel material. A third mask material may be formed in the expanded opening to protect an underlying portion of gate material during a gate etch that forms a trench bifurcating the underlying portion of gate material from an adjacent portion of gate material. The underlying portion of gate material extends laterally beyond the channel material by an amount that is substantially symmetrical about a centerline of the channel material and this amount has a height well controlled relative to the channel material.

Abstract: An integrated circuit structure includes a source or drain region, and a contact for the source or drain region. The contact has (i) an upper portion outside the source or drain region and (ii) a lower portion extending within the source or drain region. For example, the source or drain region wraps around the lower portion of the contact, such that an entire perimeter of the lower portion of the contact is adjacent to the source or drain region.

Abstract: Integrated circuit cell architectures including both front-side and back-side structures. One or more of back-side implant, semiconductor deposition, dielectric deposition, metallization, film patterning, and wafer-level layer transfer is integrated with front-side processing. Such double-side processing may entail revealing a back side of structures fabricated from the front-side of a substrate. Host-donor substrate assemblies may be built-up to support and protect front-side structures during back-side processing. Front-side devices, such as FETs, may be modified and/or interconnected during back-side processing. Electrical test may be performed from front and back sides of a workpiece. Back-side devices, such as FETs, may be integrated with front-side devices to expand device functionality, improve performance, or increase device density.

Abstract: Composite IC chip including a chiplet embedded within metallization levels of a host IC chip. The chiplet may include a device layer and one or more metallization layers interconnecting passive and/or active devices into chiplet circuitry. The host IC may include a device layer and one or more metallization layers interconnecting passive and/or active devices into host chip circuitry. Features of one of the chiplet metallization layers may be directly bonded to features of one of the host IC metallization layers, interconnecting the two circuitries into a composite circuitry. A dielectric material may be applied over the chiplet. The dielectric and chiplet may be thinned with a planarization process, and additional metallization layers fabricated over the chiplet and host chip, for example to form first level interconnect interfaces. The composite IC chip structure may be assembled into a package substantially as a monolithic IC chip.
