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.

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.

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.

Focuses on advanced pixel architectures, often involving vertical stacking (3D) or silicon-on-insulator (SOI) structures, to improve performance, density, or functionality of photodiodes, transistors, and floating diffusion regions within image sensor pixels.

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.
