Global Semiconductor Advanced Packaging Market 2025 - Trends, and Competitive Landscape in the Post-Moore Era

Semiconductor Advanced Packaging Market Definition and Analysis
Semiconductor packaging refers to the series of processing steps applied to tested wafers, such as dicing, die bonding, wire bonding, molding, plating, and lead cutting/forming, to produce functional semiconductor products. The packaging and testing (OSAT) process ensures that chips can operate reliably and stably. The quality of packaging technology directly affects whether a chip can function properly. A key indicator of advanced packaging is the ratio of chip area to package area-the closer this ratio is to 1, the better.
In the OSAT industry chain:

Upstream: Packaging/testing equipment and materials
Midstream: Packaging and testing service providers
Downstream: Fabless companies, etc.

Packaging can be divided into traditional packaging and advanced packaging, with significant differences in equipment, materials, and technologies required. While traditional packaging mainly serves to protect chips and ensure electrical connections, advanced packaging focuses on achieving miniaturization and high-density integration of chips without upgrading chip manufacturing nodes, while also reducing costs. This aligns with the industry's trend toward smaller size, higher performance, and lower power consumption in high-end chips.
Currently, packaging technologies such as Flip-Chip (FC), Wafer-Level Packaging (WLP), System-in-Package (SiP), 2.5D, and 3D packaging are considered part of advanced packaging.
With Moore's Law slowing down, advancements in chip process nodes have become more difficult. In the post-Moore's Law era, advanced packaging has emerged as a key breakthrough to enhance overall system performance. The focus has shifted from "how to make the chip smaller" to "how to package the chip smaller," making advanced packaging a strategic focus in the semiconductor industry.

Comparison of Major Advanced Packaging Technologies
Advanced packaging is developing in two main directions. The first is to develop towards the upstream wafer process field (wafer-level packaging), directly implementing the packaging process on the wafer. The main technologies include bumping, TSV, fan-out, fan-in, etc.; the second is to develop towards the downstream module field (system-level packaging), integrating processors, storage chips, capacitors, resistors, etc. into a chip, compressing the module volume, and improving the overall functionality and flexibility of the chip system. The main technology includes system-level packaging products that use flip-chip technology (FC).
Key Development Trends
1. Advanced Packaging: A Key Path Beyond Moore's Law
Currently, there are two main trends in the development of integrated circuits. The first is to continue Moore's Law, aiming to improve the performance of individual chips by further exploring transistor scaling technologies, such as FinFET and GAA processes. The second is to surpass Moore's Law, with advanced packaging technology being a key track. This aims to improve system performance by integrating multiple chips with varying performance characteristics into a single system, enhancing overall performance and functionality through cost-effective system-on-chip systems. Driven by new technologies such as chiplets and HBM, advanced packaging is becoming increasingly important. It not only enables miniaturization and high-density integration, but also reduces costs, aligning with the evolving trend of high-end chips towards smaller size, higher performance, and lower power consumption.

2. System-in-Package (SiP)
System-in-Package (SiP) is a major growth driver in the advanced packaging market. SiP allows the integration of multiple dies with different functionalities (e.g., processors, sensors, memory), various electronic components (e.g., resistors, capacitors, inductors, filters, antennas), and even MEMS and optical devices into a single package.

SiP offers great flexibility, with R&D costs and timelines much lower than similarly complex SoCs. Depending on chip assembly methods, SiP can be classified into 2D, 2.5D, and 3D structures.

3. High-Density Fine-Pitch Flip-Chip (FC)
Flip-Chip (FC) technology has substantial growth potential in mobile and consumer markets. "Flip-Chip" is a packaging method in contrast to traditional Wire Bonding (WB).
In WB, chips are connected to substrates using metal wires, with the chip's active surface facing up. In FC packaging, solder bumps are deposited directly or via RDL (Redistribution Layers) on the chip's I/O pads. The chip is then flipped and heated, allowing the molten solder to bond with the substrate, with the active side facing down.
Compared to WB, FC technology offers:
 Higher I/O count
 Shorter interconnects and better electrical performance
 Improved heat dissipation and lower chip temperature
 Smaller package size and weight
According to LookWhole Insight, the Flip-Chip Chip Scale Packaging (FC-CSP) market is projected to exceed $10 billion by 2026. FC-CSP plays a key role in mobile and consumer markets, used in smartphone APUs, RF modules, DRAM, PCs, servers, and automotive applications.

4. Wafer-Level Chip Scale Packaging (WLCSP)
According to LookWhole Insight, the WLCSP market size reached $20 billion in 2024. WLCSP involves packaging chips at the wafer level, rather than after wafer dicing. This method offers greater bandwidth, higher speed and reliability, and lower power consumption.
WLCSP supports a broad range of form factors for multi-chip packaging used in mobile electronics, HPC, gaming, AI, and IoT devices.
Applications span:
 Consumer electronics
 Automotive
 Telecom
 Healthcare
The rise of IoT devices and smart technologies is driving demand for compact, high-performance advanced packaging solutions. Yole predicts the WLCSP segment will reach a market value of approximately $2.2 billion by 2027.
Key growth drivers include:
 Expansion of consumer electronics, increasing demand for compact and efficient packages
 Proliferation of wearables and IoT devices, driving miniaturization and performance enhancements
 WLCSP's ability to improve electrical performance while shrinking device size
 The shift in the automotive sector toward EVs and ADAS, increasing demand for high-performance semiconductors
Current applications of WLCSP mainly include sensor packaging, such as:
 Various CMOS image sensors (CIS)
 Under-display fingerprint sensors
 3D imaging
 MEMS chips
 Ambient light sensors
 5G RF chips, etc.

Global Semiconductor Advanced Packaging Market: Competitive Landscape
Advanced packaging is primarily dominated by OSATs (Organized System Assembly and Testing), with the top five suppliers accounting for approximately 65% of the industry's total market share. Leading foundries, integrated device manufacturers (IDMs), and OSATs have progressively developed various packaging formats with higher I/O density. These include ultra-high-density fan-out (UHD FO), 2.5D, 3D, embedded silicon bridge, and hybrid bonding. As the I/O pitch corresponding to these packaging formats decreases, connection density continues to increase. According to Yole data, OSATs are the primary players in the mid-to-low-end I/O density segment (including Core FO, Filip Chip, and UHD FO packaging processes). In 2.5D packaging, TSMC provides interposers and back-end packaging services, while OSATs and IDMs collaborate to provide silicon interposers and packaging and testing services. TSMC, Samsung, and Intel are key players in high-end advanced packaging technology, engaging in fierce competition in this field. Top OSATs such as Amkor, JCET, and ASE are also actively expanding into the high-end advanced packaging market, but currently focus on contract manufacturing for foundries and integrated device manufacturers (IDMs).
Key technologies are primarily controlled by the world's leading OSATs, advanced wafer foundries, and IDMs, including JCET, ASE, Amkor, TSMC, Samsung, and Intel.
Leading foundries and their solutions include TSMC (InFO, integrated fan-out), ASE (FOCoS, fan-out chip on substrate for post-assembly), Samsung (2.5D RDL), and Amkor Technology (S-SWIFT, high-density fan-out lines).
