Advanced packaging equipment
The integration tools and platforms that combine multiple dies — 2.5D interposers, 3D stacks, and chiplets — into a single high-performance package.
In short
Advanced packaging equipment builds multi-die packages: placing several dies on an interposer (2.5D), stacking dies vertically (3D), and integrating chiplets. It treats the package as a system, not just protection for one chip.
Why it matters
As single-chip scaling slows, putting multiple optimized dies together in one package delivers more performance and bandwidth. Advanced packaging has become a primary way to keep systems improving — making back-end equipment strategically important.
Beginner intuition
Instead of one big chip, advanced packaging combines several smaller dies very close together so they act like one — on a silicon 'interposer', stacked in 3D, or connected as chiplets.
The package becomes part of the system design, not an afterthought.
Where it fits in manufacturing
An integration layer spanning interconnect, bonding, and assembly for 2.5D, 3D, and chiplet products; it builds on flip-chip, wafer-level packaging, and advanced bonding.
How it works
What goes in
- Multiple known-good dies (and often interposers)
- High-density interconnect and substrate materials
What happens inside
- Integrate the base: build or place the high-density routing base (for example an interposer).
- Place & join dies: attach multiple dies with flip-chip or bonding, aligned precisely.
- Build up & finish: add stacking or RDL, encapsulate, and prepare for test.
What comes out
- A multi-die package integrating several chips into one high-performance unit.
Major subsystems
High-accuracy placement / bonding
Places and joins multiple dies precisely.
Interposer / RDL processing
Builds the dense routing between dies.
Assembly & encapsulation
Completes and protects the multi-die package.
Process parameters that matter
- Interconnect density
- How many die-to-die connections are possible.
- Placement accuracy
- Alignment across multiple dies — critical.
- Warpage / stress
- Managing stress across a large multi-die package.
- Known-good-die yield
- All dies must be good, so incoming yield compounds.
A note on numbers
Common issues
What can go wrong:
- Any bad die → a failed multi-die package (compounded yield)
- Misalignment across dies
- Warpage from mixed materials
- Interconnect voids or opens
Yield implications
With several dies per package, overall yield depends on every die being good, so known-good-die screening and assembly precision are decisive.

How this fits into manufacturing
A result is never the equipment alone. For Advanced packaging, it comes from process + equipment + material + control + metrology together.
Packaging connection
Advanced packaging is where packaging becomes system integration — 2.5D, 3D, and chiplets.
Packaging →Supply-chain connection
It draws on interposers, high-density substrates, and bonding materials, and is a strategic, capacity-constrained part of the supply chain.
Supply chain →You just learned
- How advanced packaging integrates multiple dies into one package
- The roles of 2.5D, 3D, and chiplets
- Why known-good-die yield compounds across a multi-die package
- How bonding and substrates enable heterogeneous integration
Now you know
You can see why packaging has become system integration, and a primary way performance keeps improving as classical scaling slows.
