Will 2024 be the 12 months of superior packaging?

Superior packaging expertise continues to make waves this 12 months after being a distinguished spotlight in 2023 and is intently tied to the fortunes of a brand new semiconductor business star: chiplets. IDTechEx’s new report titled “Superior Semiconductor Packaging 2024-2034: Forecasts, Applied sciences, Purposes” explores superior packaging’s present panorama whereas going into element about rising applied sciences akin to 2.5D and 3D packaging.

After fabs manufacture chips on silicon wafers by means of numerous superior processes, packaging services obtain accomplished wafers from fabs, minimize them into particular person chips, assemble or “package deal” them into ultimate merchandise, and take a look at them for efficiency and high quality. These packaged chips are then shipped to unique gear producers (OEMs).

That’s a part of the standard semiconductor manufacturing worth chain by which engineers construct system-on-chips (SoCs) on silicon wafers after which transfer them to standard packaging processes. Enter chiplets, manufactured of particular person system modalities as standalone chips or chiplets on a wafer, then integrating these separate functionalities right into a system by means of superior packaging.

This premise brings superior packaging to the forefront of semiconductor manufacturing innovation. In actual fact, the way forward for chiplets is intertwined with developments in superior packaging, the place 2.5D and 3D applied sciences are quickly taking form to facilitate the business realization of chiplets.

2.5D and 3D packaging

Whereas 1D and 2D semiconductor packaging applied sciences proceed to dominate many purposes, future developments relate to 2.5D and 3D packaging to realize the conclusion of more-than-Moore semiconductor realm. These applied sciences leverage wafer-level integration for miniaturization of elements, resulting in higher interconnection densities.

2.5D expertise, which facilitates bigger packaging areas, mandates a shift from silicon interposers to silicon bridges or different alternate options akin to high-density fan-out. However packaging elements of various supplies collectively additionally results in many challenges. The IDTechEx report asserts that discovering the suitable supplies and manufacturing methods is essential for two.5D packaging adoption.

Subsequent, 3D packaging brings new buildings into play. That features integrating one lively die on high of one other lively die and decreasing bump pitch distance. This 3D approach—known as hybrid bonding—can be utilized for purposes akin to CMOS picture sensors, 3D NAND flash and HBM reminiscence, and chiplets. Nonetheless, like 2.5 packaging, 3D packaging entails manufacturing and price challenges as methods like hybrid bonding demand new high-quality instruments and supplies.

OSAT and EDA traction

The event of an ecosystem typically affords important clues about the way forward for a nascent expertise like superior packaging. Whereas challenges abound, latest semiconductor business bulletins bode effectively for IC packaging capabilities within the 2.5 and 3D eras.

Amkor, a serious outsourced semiconductor meeting and take a look at (OSAT) service supplier, is investing roughly $2 billion to construct a complicated packaging and take a look at facility in Peoria, Arizona. The 55-acre website will likely be prepared for manufacturing in a few years.

Then there may be Silicon Field, a complicated panel-level packaging foundry specializing in chiplet integration, packaging, and testing. After organising a complicated packaging facility in Singapore, the corporate is constructing a brand new website in Northen Italy to higher serve fabs in Europe.

EDA toolmakers are additionally taking note of this promising new panorama. As an illustration, Siemens EDA is working intently with South Korean OSAT nepes to increase its IC packaging capabilities for the 3D-IC period. Siemens EDA is offering nepes instruments to sort out the broad vary of complicated thermal, mechanical, and different challenges related to growing superior 3D-IC packages.

Siemens EDA’s Innovator3D IC toolset proven above makes use of a hierarchical machine planning strategy to deal with the huge complexity of superior 2.5D/3D built-in designs with tens of millions of pins. Right here, designs are represented as geometrically partitioned areas with attributes controlling elaboration and implementation strategies. That, in flip, permits essential updates to be rapidly applied whereas matching analytic methods to particular areas, avoiding excessively lengthy execution instances.

In the meantime, new supplies and manufacturing processes will proceed to be developed to confront the challenges dealing with 2.5D and 3D packaging. Maybe one other replace earlier than Christmas will present higher readability on the place superior packaging expertise stands in 2024 and past.
