The packages were assembled with known-good die
, which were bonded with 2.
The Irvine Sensors process involves the thinning and rewiring of one or more of these known-good die
into an embedded layer, now stackable and chip-like in appearance.
The availability of known-good die
(KGD) at an acceptable price was an issue for other applications.
The major difference is that today's inteposers have TSVs, but some issues, such as ensuring a high-yield process is used to produce the substrate, mounting known-good die
, thermal issues, and infrastructure, have not changed.
Wafer-level burn-in and test enables lower cost production of Known-Good Die
(KGD) for multi-chip modules and systems-in-a-package.
As part of the agreement, RedMere will provide known-good die
(KGD) connectivity products for the HDTV and consumer multimedia markets to Fairchild.
This follow-on order validates the DiePak carrier as a cost-effective solution for producing Known-Good Die
for multichip modules (MCMs) using advanced memory, logic, and application-specific devices.
