OSAT Market: Growth Drivers vs. Challenges
Drivers:
- Growing Demand for Miniaturization: The increasing demand for miniaturization has led to ongoing research and development, creating new products, manufacturing processes, and semiconductor designs, accelerating the industry's growth. For instance, in September 2023, the US National Science Foundation declared that it would provide $45.6 million in support for 24 research and teaching programs, including funds from the "CHIPS and Science Act of 2022." These programs aim to boost advancements in semiconductor technology, production, and workforce development.
- Furthermore, end-use semiconductor sales experienced a significant rise. As a result of the industry's persistent efforts to accommodate the rising demand for semiconductors, its sales have increased. As more employment moved to remote work and home learning, sales of end-use categories like PCs saw notable growth. Other areas, including the automotive sector, had sharp rises, making it the third-largest semiconductor end-use market. This growth in the end-use of semiconductors significantly boosts the OSAT market expansion.
Challenges:
- Price volatility and technological complexity: The price volatility due to the supply-chain constraint is a major challenge in the industry. Further, the technological complexity is hindering market growth.
