Why Packaging Became Strategic
Historically, semiconductor progress was often described as putting more transistors on one monolithic die.
Modern high-performance systems increasingly combine multiple specialized dies.

GPU / accelerator chiplet
I/O die
HBM stacks
networking
base dieThe package becomes part of the computer architecture.
EMIB
EMIB stands for Embedded Multi-die Interconnect Bridge.
Instead of using a full silicon interposer under all dies, EMIB uses small embedded silicon bridges to connect neighboring dies at high bandwidth. [S18]
Potential benefits include:
- dense die-to-die communication;
- modular design;
- package-size flexibility;
- heterogeneous integration.
Foveros
Foveros is Intel's 3D stacking family.
It enables dies to be stacked vertically rather than only placed side by side.
This can shorten interconnect distances and allow different functions to use different manufacturing processes.
Foveros Direct
Foveros Direct uses hybrid bonding for very dense die-to-die connections. [S18]
The strategic direction is toward packages that behave more like integrated systems than collections of discrete chips.
AI Systems
AI accelerators are one of the clearest packaging use cases.
A frontier AI package may need:
large compute dies

multiple HBM stacks
+
I/O chiplets
+
networking
+
very high power deliveryOne giant monolithic die may be impractical because of reticle limits, yield and manufacturing cost.
Packaging solves part of that constraint.
Why This Helps Intel Foundry
Packaging can attract customers even when Intel does not fabricate every die.
This creates a broader commercial model:
customer uses multiple foundries
↓
Intel integrates dies
↓
Intel earns packaging / assembly revenueThat can make Intel relevant to semiconductor systems outside its own processor families.
Manufacturing Economics
Chiplets can improve yield economics because smaller dies may be easier to manufacture successfully than one huge die.
But packaging adds its own costs and yield risks.
The real optimization is system-wide.
Competition
Intel competes with:
- TSMC advanced packaging;
- Samsung;
- OSAT providers;
- custom packaging ecosystems.
The competition involves:
- interconnect density;
- power efficiency;
- thermal performance;
- capacity;
- yield;
- time to market.
Strategic Role
Advanced packaging gives Intel a way to compete beyond transistor scaling.
That is increasingly important as the semiconductor industry moves from:
