TechSearch International’s latest report: 2022 Flip Chip and WLP: Trends and Market Forecasts examines the impact of slowing consumer demand on the flip chip and WLP market growth. The report includes an examination of both fan-in WLP and fan-out WLP markets. The report also examines bump pitch trends and the role of hybrid bonding.

Chiplet architectures are increasingly being adopted to achieve the economic advantages lost with the high cost of silicon scaling on advanced nodes. With chiplet designs, more silicon is needed to support the disaggregation of the monolithic die into smaller intellectual property (IP) building blocks. Many devices have made the conversion from solder bumps to Cu pillar. FO-WLP processes in production using the Deca M-Series™ and TSMC’s InFO use a Cu pillar on the native wafer. Reduced demand for smartphones and PCs this year is changing demand for flip chip packages, but growth will continue. The compound annual growth rate (CAGR) for all types of flip chip devices in units from 2021 to 2026 is 4.5 percent. This includes both solder bump and Cu pillar. Industry-wide capacity utilization was extremely high last year, but has decreased more than 10 percent this year. With continued capacity expansion, utilization will not reach levels seen in 2021 over the next several years.

Despite lower demand for consumer products such as smartphones, Fan-in WLP shipments will increase this year because of continued growth in image sensor demand, particularly for surveillance cameras in China. The WLP count continues to climb for most products. In a few cases, WLP counts have declined in products due to higher levels of integration. The projected CAGR from 2021 to 2026 in units is 7.83 percent. Devices using FO-WLP include application processors, RF, PMICs, audio CODEC, envelope trackers, automotive radar, and some image sensors. Single die are common and multi-die configurations are increasing. A 6.3 percent CAGR in units is projected for 2021 to 2026. Several companies are researching, developing, or installing panel-based production lines. A variety of approaches for large-area production have been developed.

The market for heterogeneous integration is projected to grow 10% in number of packages from 2020 to 2025, reaching almost 54 billion packages. Smartphones, wearables, and consumer packages account for the largest number. RF front-end modules including the latest 5G mmWave modules and wireless connectivity modules for Wi-Fi, Bluetooth, and other networks account for nearly half of all heterogeneous integration devices counted in this report. High-performance computing, 5G telecommunications infrastructure, networking, stacked memory, automotive, and medical applications also contribute to the growth in heterogeneous integration packages.

The market for packages using chiplets is expected to show a CAGR of 104% from 2020 to 2025. A chiplet is a functional circuit block and includes reusable IP blocks. It is a physically realized and tested IP with a standard or proprietary communication interface between IP blocks. A chiplet functions with other chiplets, so the design must be co-optimized and the silicon cannot be designed in isolation. An increasing number of companies are turning to chiplets to achieve the economic advantages lost with expensive monolithic scaling, ushering in a new era of smart packaging. The adoption of chiplets represents an inflection point in IC design for CPUs and GPUs; similar to the transition from perimeter pad design to area array with the adoption of flip chip interconnect. It is also possible to have higher core counts and therefore higher performance than with a monolithic design. There is a potential for improved power distribution. Binning the chiplets provides an opportunity to optimize performance even further. Chiplets have been adopted for server processors and AI accelerators, desktop and laptop processors, networking, and adoption in mobile applications such as smartphones and tablets is anticipated. Chiplets can be configured side-by-side or as a 3D stack. The 3D stack may use microbumps, but the direct Cu-to-Cu bonding method provides some of the greatest density and electrical advantages.

Quantifying the Impact of Heterogeneous Integration: Chiplets and SiP is a 130-page report with full references and an accompanying set of 122 PowerPoint slides.
