WALTON ADVANCED ENGINEERING, INC.

Methods and structures for integrating and enclosing electronic components into compact, multi-functional modules, often involving embedded components, multi-layer substrates, and electromagnetic shielding for performance and miniaturization.

Packaging technologies where bare dies are embedded within a mold compound or substrate cavity, and then interconnected using redistribution layers (RDLs) for fan-out or compact integration, often avoiding through-silicon vias in the chips themselves.

Combining different types of functional chiplets (e.g., compute, memory, I/O, optical, power, biological) into a single package or system, often to optimize performance, power, or cost by leveraging specialized components.

Techniques for stacking multiple semiconductor dies or active layers vertically to achieve higher density and shorter interconnections, often utilizing through-silicon vias (TSVs) or other vertical conductive paths like through-hole electrodes.

Development of novel materials and designs for bonding, sealing, and underfill applications, focusing on improving mechanical integrity, electrical performance, and preventing defects like cracks or delamination in chip-to-chip connections.

Novel electrical connection methods within or between package components, including through-glass vias (TGVs), backside contacts, and optimized redistribution layers for improved signal and power integrity.

Technologies for establishing and maintaining secure communication channels between devices or networks, often employing encryption, secure protocols, or virtual private networks (VPNs).

Integrated solutions for dissipating heat generated by high-density semiconductor devices within the package, including embedded cooling structures, cold plates, and optimized fluidic channels.

Novel materials and processes for forming low-resistance electrical contacts and interconnects within semiconductor devices, including selective deposition, silicidation, and barrier layers for improved performance and scaling.

Methods for temporarily attaching a wafer or substrate to a carrier for thinning, dicing, or other processing, followed by controlled debonding, often using light-sensitive resins, temporary adhesives, or roughened interfaces.

Materials and processes for hermetic encapsulation, conformal coating, optical chip sealing, and stretchable conductors for electronic and optoelectronic devices.
