The market for redistribution layer materials was valued at approximately US$ 192.39 million in 2022 and is projected to grow to US$ 460.15 million by 2030, reflecting an estimated compound annual growth rate (CAGR) of 11.5% from 2022 through 2030.
The advanced packaging process initiates at the die level, with the primary goal of reducing die sizes while maintaining input-output (I/O) density. Various emerging packaging technologies are pivotal in the heterogeneous integration of devices. One significant technology is wafer-level fan-out packaging (WLFO), which has developed into a comprehensive packaging solution. Initially, the WLFO process was limited to single-die designs, featuring a single redistribution layer (RDL) on one side of a reconstituted wafer.
The redistribution layer is a vital component in advanced wafer packaging. It facilitates the rerouting of the I/O layout, enabling a higher number of I/Os. An increased I/O density typically enhances electrical performance, as it allows for quicker electrical signals between the die and reduces the likelihood of electrical shorts. Furthermore, a higher I/O density contributes to improved overall package performance. Additionally, Asia's strategic position as a global manufacturing center, combined with competitive production costs, has drawn multinational companies aiming to streamline their supply chains. This has fostered a robust ecosystem for the redistribution layer material market, with numerous suppliers and manufacturers establishing operations in the region.
The redistribution layer material market is categorized by type into polyimide (PI), polybenzoxazole (PBO), benzocyclobutene (BCB), and other materials. In 2022, the polyimide (PI) segment dominated the market share. Polyimides are thermoplastic polymers characterized by high melt viscosity and the necessity for elevated pressures during the molding process. They provide excellent chemical resistance, substantial mechanical strength, high thermal stability, and outstanding electrical properties. In integrated circuit (IC) packaging, polyimides are utilized as high-temperature adhesives, mechanical stress buffers, and as films supporting micro-sized circuitry. However, a significant drawback of polyimides is their requirement for high curing temperatures, which conflicts with the demand for lower curing temperatures in packaging. Consequently, several material suppliers are focusing on developing polyimides that cure at lower temperatures. PI is predominantly used in flip-chip wafer bumping and wafer-level packaging (WLP) applications. The market is also divided by application into fan-out wafer level packaging (FOWLP) and 2.5D/3D IC packaging, which includes high bandwidth memory (HBM), multi-chip integration, package on package (FOPOP), among others. The 2.5D/3D IC packaging segment held a significant market share in 2022. The rising costs associated with lithography steps and wafer processing at next-generation silicon nodes are prompting the industry to seek alternatives to enhance the performance and functionality of electronic devices. Moreover, the integration of diverse technologies such as logic, memory, RF, and sensors into compact form factors is steering the semiconductor industry towards 3D integration as a viable solution.
In 2022, the Asia Pacific region accounted for the largest share of the global redistribution layer material market. This region is recognized as a global manufacturing hub due to its diverse manufacturing sectors. With China evolving into a high-skilled manufacturing center, developing nations like India, South Korea, Taiwan, and Vietnam are attracting businesses that aim to shift their low to medium-skilled manufacturing operations to nearby countries, resulting in lower labor costs. According to a report by the Semiconductor Industry Association, approximately 75% of global semiconductor capacity is located in East Asia. Semiconductor firms can expect a cost advantage ranging from 25% to 50% by initiating manufacturing activities in this region.
Key players in the global redistribution layer material market include SK Hynix Inc, Samsung Electronics Co Ltd, Infineon Technologies AG, Dupont De Nemours Inc, Fujifilm Holdings Corp, Amkor Technology Inc, ASE Technology Holding Co Ltd, NXP Semiconductors NV, JCET Group Co Ltd, and Shin-Etsu Chemical Co Ltd. These market participants are committed to delivering high-quality products to meet customer needs. They are also implementing strategies such as investing in research and development and launching new products.
