Framework diagram for the development, design, and production activities of image sensor chips
Overview
In order to systematically promote the whole process management of image sensor chip from concept to mass production, and ensure the progressiveness of technology, design reliability and manufacturing consistency, this "Frame Diagram of Image Sensor Chip Development, Design and Production Activities" is hereby formulated. This framework integrates multidimensional activities such as research and development, engineering, manufacturing, and quality control, and is suitable for the research and industrialization of high-end chips such as CMOS image sensors (CIS), helping enterprises achieve an efficient, controllable, and iterative chip development system. By standardizing processes and optimizing collaboration mechanisms, enterprises can effectively respond to challenges such as rapid technological iteration, changing market demand, and complex manufacturing processes, ultimately achieving an increase in product competitiveness and market share.
Adopting a "stage progression+multiple verifications+feedback loop" structure, highlighting the high investment, high risk, and high-precision characteristics of chip development. Multiple technical review points (TRs) and gates are set up in the process to ensure that key nodes are controllable. At the same time, emphasis is placed on cross departmental collaboration (R&D, engineering, manufacturing, quality) and external resource integration (foundries, EDA suppliers, equipment manufacturers) to build a collaborative development ecosystem.
Chip front-end design
Production preparation and process introduction
Key support system
support system | Instructions |
EDA toolchain | Use tools such as Cadence (Virtuoso, Spectre), Synopsys (Custom Compiler, PrimeSim) to complete design and simulation, and improve design efficiency. |
IP reuse mechanism | Build standardized IP libraries (such as high-precision ADCs and digital interface IPs) to shorten development cycles and reduce risks. |
project management | Adopting the Integrated Product Development (IPD) process, setting up Technical Review Points (TR1-TR6) and Decision Review Points (DCP) to ensure that the project progresses as planned. |
Quality and reliability | Following ISO 9001 and ISO 26262 standards, establish a Failure Mode and Effects Analysis (FMEA) system to identify risks in advance. |
supply chain collaboration | Establish strategic partnerships with contract manufacturers (TSMC, Samsung, SMIC) and packaging factories (Sunlight, Changdian Technology) to ensure production capacity and delivery time. |
Intellectual Property Management | Apply for core patents (such as pixel structures and noise reduction algorithms), establish patent barriers, and prevent intellectual property disputes. |
Framework features
Application suggestions
The image sensor chip is the core of intelligent vision systems, and its development involves interdisciplinary and high-precision engineering implementation. This framework diagram provides a systematic and standardized development path, which helps enterprises improve R&D efficiency, reduce trial and error costs, and ensure product quality through process optimization, technical collaboration, and data closure. In the future, with the development of emerging fields such as AI, autonomous driving, and metaverse, image sensor chips will evolve towards higher resolution, lower power consumption, and stronger environmental adaptability. Enterprises need to continuously invest in technological innovation, combine advanced processes and algorithm breakthroughs, and build core competitiveness. At the same time, we will strengthen the cooperation between industry, academia, and research, as well as the synergy of the industrial chain, to promote the high-end and independent development of China's image sensor industry.
