Liquid Encapsulant (LMC), as an important branch of Epoxy Molding Compound, plays a crucial role in advanced semiconductor packaging processes. This type of material is mainly used in high-end fields such as fan-out wafer-level packaging (FOWLP) and 2.5D/3D packaging, and especially plays an irreplaceable role in high-bandwidth memory (HBM) packaging processes. The global liquid encapsulant industry is highly concentrated and mainly led by Japanese companies, which occupy a dominant position in the global market by virtue of their technical accumulation and advanced R&D capabilities.

The production of liquid encapsulant (LMC) has high technical and customer barriers. In terms of technical barriers, LMC formulations need to balance multiple conflicting requirements such as fluidity, low warpage and high reliability, making R&D difficult and demanding high process control. In terms of customer barriers, as a key material for semiconductor packaging, products entering downstream chip or packaging/testing manufacturers need to undergo 1-2 years of product certification, making entry difficult for new entrants.

In addition, these major Asian liquid encapsulant manufacturers provide key packaging material support to the global semiconductor industry through continuous technological innovation and product development, especially playing an important role in advanced packaging technologies such as HBM and 2.5D/3D packaging. With the rapid growth of emerging markets such as AI, 5G, high-performance computing and the Internet of Things, demand for advanced packaging technology has surged, driving the expansion of the LMC market. According to market data, the global LMC market size is expected to grow from several hundred million US dollars in 2024 to the billion US dollar level by 2030, with a compound annual growth rate exceeding 30%.

Epoxy Molding Compound (EMC), as a key material for semiconductor packaging, has an industry landscape that directly reflects the current development status and trends of the global semiconductor industry. The EMC market is highly concentrated and mainly led by Japanese companies, which occupy a dominant position in the global market by virtue of their technical accumulation and advanced R&D capabilities. In recent years, with the rapid development of China's semiconductor industry, domestic EMC companies are also gradually emerging, and the market landscape is undergoing subtle changes.

In terms of regional distribution, the Asia-Pacific region is the largest epoxy molding compound market, with a share of about 86%, followed by North America with about 6% of the market share. China has become the world's largest production base for epoxy molding compounds, with domestic manufacturers' annual capacity exceeding 140,000 tons, accounting for about 35% of global capacity. This distribution pattern is highly consistent with the regional distribution of the global electronics manufacturing industry, reflecting the strong influence of electronics manufacturing on EMC demand.

The global EMC market is highly concentrated, mainly because EMC production has high technical and capital barriers. EMC formulations need to balance multiple conflicting requirements such as fluidity, low warpage and high reliability, making R&D difficult and demanding high process control. At the same time, as a key material for semiconductor packaging, products entering downstream chip or packaging/testing manufacturers need to undergo 1-2 years of product certification, making entry difficult for new entrants. These factors together have led to the highly concentrated landscape of the global EMC market.
