Core Viewpoint - The article discusses the importance and evolution of semiconductor packaging technology, highlighting its critical role in enhancing chip performance, reducing power consumption, and enabling efficient system integration to meet the challenges posed by Moore's Law and complex application demands [27]. Group 1: Semiconductor Packaging Process - Semiconductor packaging technology is categorized into four levels: Level 0 (wafer cutting), Level 1 (chip-level packaging), Level 2 (mounting chips onto modules or circuit boards), and Level 3 (installing circuit boards with chips and modules onto system boards) [2]. - The primary functions of semiconductor packaging include mechanical protection, electrical connection, mechanical connection, and heat dissipation [9][12]. Group 2: Development Trends in Semiconductor Packaging - Key trends in semiconductor packaging technology include the development of materials with better thermal conductivity and packaging structures that effectively dissipate heat [13]. - The demand for packaging technologies that support high-speed signal transmission is increasing, particularly for applications in AI and 5G wireless communication [14]. - The trend towards three-dimensional semiconductor stacking technology allows multiple chips to be integrated within a single package, enhancing performance and efficiency [18]. - There is a growing emphasis on miniaturization of semiconductor devices to meet the needs of mobile and wearable products [19]. - Packaging technology must also ensure reliability in extreme environments, such as tropical rainforests and outer space [19]. Group 3: Advanced Packaging Technologies - Advanced packaging aims to improve chip performance, integration, and reliability through various methods, including Fan Out, System in Package (SiP), and 2.5D/3D packaging [27][28]. - The market for advanced packaging is projected to grow significantly, with wafer production expected to increase from approximately 36 million in 2023 to about 64 million by 2029, reflecting a compound annual growth rate (CAGR) of 9% [31]. Group 4: Testing and Validation of Packaging - Two methods are used to develop and ensure the effectiveness of semiconductor packaging: utilizing existing packaging technologies for new chips and developing new packaging technologies for existing chips [33]. - The packaging design process involves simultaneous development with chip design to optimize characteristics and ensure feasibility before mass production [34][36].
