Amkor Technology
Outsourced semiconductor assembly and test
Provides package design, wafer preparation, die attach, wire bond, flip chip, stacked-die assembly, and semiconductor test services.
What public evidence supports
Amkor describes stacked-die, wire-bond and flip-chip assembly, advanced wafer thinning, RDL processes, and test services.
Evidence boundary
A published package platform or technical paper does not establish qualification for a named product or production commitment.
Linked process capabilities
The links below show where the documented capability fits in the chip lifecycle. They are not customer or qualification claims.
Process
Advanced packaging
How substrates, RDL, interposers, TSVs, fan-out, chiplets, memory stacks, assembly, test, and thermal design become one system.
Process
Wafer sort
How process-monitor structures and individual die are electrically probed before assembly, generating parametric evidence and known-good-die candidates.
Process
Thinning & dicing
How finished wafers are protected, back-ground, stress-relieved, singulated, inspected, picked, and transferred without damaging thin die.
Process
Substrates & RDL
How organic substrates, interposers, and redistribution layers fan dense die connections into package-scale power, signal, and board interfaces.
Process
Wire bond & flip chip
How die are attached and electrically connected by fine wires or area-array bumps, and why each architecture creates different process windows.
Process
Underfill & encapsulation
How polymeric materials fill interconnect gaps, redistribute stress, protect die and wires, and become a permanent part of package reliability.
Process
Final test & burn-in
How packaged devices are screened, characterized, binned, stressed, and exercised in increasingly system-like conditions before shipment.
