Third-party IC packaging and test services are offered by outsourced semiconductor assembly and test vendors. Foundries and integrated device manufacturers (IDMs) having internal packaging operations also connect with OSATs for part of their IC packaging needs. The foundries and/or OSATs handle packaging for the fabless firms.
The packaging is made to safeguard the semiconductor as well. Semiconductors still need to be able to perform as intended after they are outside of facilities created particularly to reduce contaminants. They can endure dampness and other materials due to packaging. The process of making a semiconductor involves many distinct parties. First, raw semiconductor minerals like silicon must be taken out of the earth. Then, semiconductors need to be designed, produced, packaged, and go through other procedures. OSATs take on time-consuming activities when a semiconductor fab's time and capacity need to be maximized, resulting in a large supply of semiconductors.
The demand for semiconductor chips is increasing in a wide range of industries, including consumer electronics, automotive, and healthcare. This is expected to drive the need for specialized services provided by OSAT companies, including packaging, assembly, and testing. The semiconductor industry is constantly evolving, with new and innovative technologies emerging. OSAT companies are well-positioned to capitalize on these advancements, providing specialized services for advanced packaging and testing solutions.
Furthermore, the semiconductor industry is experiencing significant growth in emerging markets, such as China and India. This is also increasing the need for localized OSAT services, as semiconductor manufacturers seek to reduce costs and improve efficiency.
Furthermore, semiconductor chips are becoming increasingly complex, requiring specialized expertise and equipment for packaging and testing. This is driving the need for OSAT companies, which have the expertise and resources to provide these specialized services. OSAT companies are partnering with semiconductor manufacturers and other industry players to develop new technologies and solutions. These collaborations are expected to drive growth and innovation in the OSAT market.

Increasing demand for semiconductor chips
The increasing demand for semiconductor chips from various industries, including automotive, industrial, consumer electronics, and healthcare, is expected to augment the growth of the outsourced semiconductor assembly and test services market during the forecast period. The semiconductor industry is a key enabler for these industries, as modern electronic systems require a high degree of integration and complexity, which can only be achieved through advanced semiconductor solutions. OSAT companies play a crucial role in the semiconductor industry by providing packaging, assembly, and testing services to semiconductor manufacturers. These services enable semiconductor manufacturers to focus on their core competencies, such as design and wafer fabrication, while outsourcing the assembly and testing of their chips from proper OSAT companies.
The automotive industry is increasingly reliant on semiconductor chips for advanced safety features, electric vehicle drivetrains, and infotainment systems. The industrial sector is also using semiconductor chips for automation, robotics, and the Internet of Things (IoT). The consumer electronics industry is driving demand for smaller, more powerful, and energy-efficient devices, while the healthcare industry is using semiconductor chips for medical devices and equipment. These trends are driving the demand for advanced packaging and testing solutions, which can be provided by OSAT services companies. Advanced packaging technologies, such as 2.5D and 3D packaging, are becoming increasingly important, as they enable higher performance and lower power consumption for semiconductor chips. OSAT companies are investing in advanced packaging solutions to meet the growing demand from semiconductor manufacturers.
Fluctuating demand for semiconductor chips
The fluctuating demand for semiconductor chips is a significant challenge for OSAT companies as it can result in revenue volatility and financial uncertainty. This is due to the fact that the demand for semiconductors is subject to various macroeconomic and industry-specific factors, such as changes in consumer preferences, economic conditions, and supply chain disruptions. For instance, the COVID-19 pandemic caused a significant disruption in the semiconductor supply chain, leading to a surge in demand for certain types of semiconductors and a decline in demand for others. The revenue volatility caused by fluctuating demand can lead to challenges for OSAT companies in terms of capacity utilization, inventory management, and workforce planning. When demand is high, OSAT companies may need to invest in additional equipment and resources to meet customer requirements. However, when demand declines, they may struggle to maintain profitability and cover fixed costs, such as salaries, rent, and depreciation.
Moreover, the fluctuating demand for semiconductors can lead to price pressures in the market, as semiconductor manufacturers may negotiate lower prices with OSAT companies during periods of low demand. This can result in reduced profit margins for OSAT companies and make it difficult for them to invest in R&D and innovation. Consequently, this is expected to restrain the growth of the outsourced semiconductor assembly and test services market within the estimated timeframe.
Increasing government efforts
The increasing government efforts to strengthen their positions in the global supply chain are anticipated to augment the growth of the market in the years to come. For instance, in February 2022, the "EU Chips Act," involving up to $43 billion in specific funding for Europe's semiconductor industry, officially started receiving consideration from the European Commission. This includes increased investments in innovative research and development as well as incentives designed to support the EU's front-end manufacturing for "first-of-a-kind" technology. Also, in December 2021, in order to entice investments in chip production, assembly testing, packaging, and chip design, the Government of India unveiled a $10 billion semiconductor incentive package.
Furthermore, in November 2021, to treble domestic chip income by 2030, Japan allocated $6.8 billion in funding for local semiconductor investment. In November 2022, for a collaborative research center with the United States, Japan suggested an additional $8 billion in investment. This would cover advanced semiconductor manufacturing lines and semiconductor materials. Additionally, in May 2021, the "K-Semiconductor Belt" concept from South Korea aims to create the largest semiconductor supply chain in the world by 2030. To encourage additional private sector investment, the initiative provides investment tax incentives for semiconductor R&D. Consequently, this will create immense growth opportunities for the market in the years to come.
On the basis of service type, the testing segment held the largest revenue share in 2023. This is owing to the growing complexity of semiconductor chips that will need improved testing services to ensure that the chips are functioning properly. This is especially true for advanced applications like artificial intelligence (AI) and the Internet of things (IoT), which require high-performance and reliable chips. Furthermore, the semiconductor industry is characterized by rapid innovation and shorter product lifecycles. As a result, there is a greater need for testing services to quickly bring new products to market while ensuring they meet quality and performance standards.
Based on the application, the consumer electronics segment held the largest market share in 2023. This is attributable to the rising proliferation of smartphones, tablets, and other connected devices which has resulted in an increase in the production of semiconductor chips for use in these products. Additionally, the trend towards miniaturization and higher functionality in electronic devices is also driving the demand for advanced packaging solutions, such as wafer-level packaging and flip-chip packaging. OSAT companies are well-positioned to offer these advanced packaging solutions and are seeing increased demand for their services as a result. These factors are likely to contribute to the growth of the segment in the global outsourced semiconductor assembly and test services market.
