Chiplet和异构集成到底是什么？

Core Viewpoint - The article discusses the emerging concepts of "chiplet" and "heterogeneous integration," highlighting the lack of standardized definitions and the implications for the semiconductor industry [2][3][4]. Summary by Sections Chiplet Definition and Characteristics - Chiplets are discrete components that can be integrated into a single package, differing from traditional multi-chip modules (MCM) [3][4]. - A key feature of chiplets is the direct connection between chips through standardized interfaces, which enhances performance and efficiency compared to MCMs [4][5]. - The economic rationale for chiplets stems from the high costs associated with advanced nodes and the inability to produce larger chips [4][5]. Standardization and Interoperability - The standardization of interfaces, such as UCIe and Bunch of Wires (BoW), is crucial for ensuring interoperability among chiplets from different sources [5][6]. - There is a debate on whether a chiplet must have a standardized interface to qualify as such, with some experts arguing that the presence of a die-to-die interface is essential [12][19]. Heterogeneous Integration - Heterogeneous integration involves combining different types of chips within a single package, which can include various nodes and materials [13][14]. - The definitions of heterogeneous integration vary, with some emphasizing the need for different functionalities among the chips involved [13][17]. - The complexity of integrating analog and photonic chips adds further challenges to the standardization of definitions in this area [10][18]. Industry Implications - The lack of consensus on definitions may hinder interoperability and complicate the development of advanced packaging processes [19]. - As the industry evolves, the need for clear definitions will become increasingly important for decision-making and market differentiation [19][20].
