后摩尔时代关键路径：132页PPT详解半导体先进封装

Core Viewpoint - The article discusses the significance of semiconductor packaging and testing (封测) in the semiconductor industry, highlighting its processes, roles, and market potential, especially in the context of China's growing semiconductor sector. Group 1: Definition, Role, and Process of Packaging - Packaging refers to the process of placing, fixing, and sealing chips using specific materials and techniques, which protects chip performance and extends internal functions to the external environment [7][8]. - The four main roles of packaging are protection, support, connection, and heat dissipation [6][8]. - The basic packaging process includes wafer thinning, wafer cutting, chip attachment, wire bonding, encapsulation, curing, testing, marking, packaging, inspection, and shipping [7][8]. Group 2: Semiconductor Packaging Industry Chain - The semiconductor packaging industry is positioned in the midstream of the semiconductor industry chain, which includes design, manufacturing, and packaging/testing [17]. - The packaging segment accounts for a significant portion of the value in the packaging and testing process, with estimates indicating that packaging contributes 80-85% of the total value [22]. Group 3: Market Overview and Growth Potential - In 2022, China's semiconductor industry sales reached 12,006 billion yuan, with packaging accounting for 2,995 billion yuan, representing 24.9% of the total [22]. - The packaging industry is expected to grow, with projections indicating a sales increase to 3,060 billion yuan in 2023, reflecting an 8.4% year-on-year growth [22]. - The article emphasizes that the advanced packaging and high-end packaging materials sectors are likely to benefit from the ongoing AI wave and supportive policies [22]. Group 4: Equipment and Technology in Packaging - The semiconductor packaging process involves various equipment, including thinning machines, cutting machines, die bonders, and encapsulation machines, each playing a critical role in ensuring quality and efficiency [32][37]. - The market for packaging equipment is dominated by a few key players, with significant market shares held by companies like TOWA and ASM Pacific [45]. Group 5: Testing Process and Equipment - Testing is crucial for ensuring the functionality and performance of semiconductor devices, with processes divided into wafer testing and final product testing [16][54]. - The global market for testing equipment is led by companies such as Advantest and Teradyne, which together hold a significant market share [48]. Group 6: Raw Materials in Packaging - The raw materials used in semiconductor packaging include cutting materials, adhesive materials, bonding wires, packaging substrates, and encapsulation materials, with the packaging substrate accounting for 40% of the market share [63][64]. - The article notes that the barriers to entry for packaging materials are lower compared to wafer materials, and China has achieved a level of import substitution in this area [63].
