OSAT Market Analysis

The outsourced semiconductor assembly and test services market size is estimated at USD 41.10 billion in 2023 and is expected to reach USD 63.67 billion by 2028, registering at a CAGR of 9.15% during the forecast period (2023-2028).

  • Outsourcing is also a major factor in the semiconductor industry. More than just design, the manufacturing aspect of semiconductor product development is dependent on the services provided by third-party vendors. Fabs (Pure-Play Foundries) and OSATs are two prominent examples of semiconductor outsourcing. OSAT semiconductor firms provide third-party integrated circuit (IC) packaging and testing services package and test semiconductor devices made by foundries before shipping them to the market. Such companies in the market provide innovative and cost-effective solutions that deliver faster processing speeds, higher performance, and functionality while taking up less space in an electronic device.
  • OSAT companies are mostly contracted by semiconductor design companies, such as Intel, AMD, and Nvidia, and execute those companies’ designs. For instance, Intel is both a chip designer and a foundry (wafer provider) owing to the fact that they own and operate their own fabs or foundries. Intel outsources its chip packaging to different OSATs for assembly and test services before shipping the chips to customers.
  • The semiconductor industry has been growing, with miniaturization and efficiency being the focus area and semiconductors emerging as building blocks of all modern technology. The advancements and innovations in this field have been directly impacting all downstream technologies. The rapid development of electronics technology, including artificial intelligence (AI) and cloud computing, is complemented by a high demand for integrated circuits (ICs) with high speed, low power consumption, and high integration, leading to its significant sales.
  • However, the significant downfall in demand for consumer electronics and declining demand for cloud services has negatively impacted the OSAT market leading to a decrease in the capacity utilization of many OSAT plants to about 50% in the first quarter of 2023. On the contrary, the introduction of advanced packaging technologies owing to the development of sophisticated electronics in both the consumer electronics and automotive sectors as well as demand for stock adjustment is expected to provide a moderate recovery of about 65% capacity utilization of OSAT in the upcoming quarters. Due to these factors, more recent semiconductor packaging technologies are being adopted to keep up with demand.
  • Although the market was severely affected by the COVID-19 pandemic, the demand for consumer electronics and computer components increased exponentially due to the enforcement of people working remotely.

OSAT Market Trends

Automotive Application Segment is Expected to Hold Significant Market Share

  • Automotive applications are one of the fastest-growing sources of demand for the OSAT market. As the complexity of automotive chips is growing with the advent of electric cars, autonomous vehicles, and advanced driver-assistance system (ADAS) systems, the complexity of automotive chip packaging is also increasing rapidly.
  • The semiconductor packaging industry is responsible for this wave of gains due to a variety of new technologies, including big data, high-performance computing (HPC), artificial intelligence (AI), edge computing, advanced memory, 5G infrastructure expansion, adoption of 5G intelligent mobile phones, growth in the use of electric vehicles, and improved car safety features, to name a few.
  • For instance, in-cabin applications such as infotainment controllers and ADAS have stringent mission-critical test requirements over wide operating temperature ranges, necessitating the need for OSAT vendors to step in. Advanced packaging technologies and a new generation of chips with high performance, reliability, and integration are made possible by packaging materials, which are essential to the growth of advanced technology applications.
  • The global millennial preference for automatic vehicles is anticipated to fuel the semiconductor packaging and testing demand. In an automatic car, there are more than 2,500 chips installed. Since it used to take longer to produce a single semiconductor a few years ago, reputable companies had to deal with a shortage of semiconductors.
  • According to IEA, Electric vehicles amounted to about 14 percent of global passenger car sales in 2022, a rise of around 5.3 percentage points year-over-year. Electric vehicle sales have rapidly increased since 2017, when they rose above one percent of the market, and have particularly accelerated since 2020. Due to increased environmental consciousness, many consumers started looking for more sustainable transportation methods amid the COVID-19 pandemic. This contributed to the EV market expansion worldwide.

South Korea is Expected to Hold Significant Market Share

  • South Korea is one of the promising markets for global OSAT vendors. The country is also home to some prominent chip makers for the consumer electronics segment, such as Samsung and SK Hynix, making it a lucrative hub for innovation in semiconductor devices.
  • The Korean government focuses on smart manufacturing and plans to have 30,000 fully-automated manufacturing companies by 2025. The government aims to achieve this by incorporating the latest automation, data exchange, and IoT technologies. This is expected to be a major driver for OSAT services in the country.
  • Moreover, the size of the country's semiconductor testing sector has grown significantly with the growth of Samsung Electronics' system semiconductor business. The semiconductor testing companies in the country, such as NEPES Ark, LB Semicon, Tesna, and Hana Micron, have been dealing with increased supplies of system semiconductors by making significant investments in necessary facilities and equipment.
  • The developments in the 5G space also led to the growth of advanced packaging of chips. According to the Ministry of Science and ICT, as of February 2023, the country has 29.13 million 5G Subscribers, an increase of 113% compared to 13.66 million 5G subscribers in February 2021.
  • Apart from this, the automotive maker Hyundai, one of the prominent automobile companies in South Korea, announced that it is planning to invest USD 21.56 billion over the next five years (2019-2023) in ADAS systems, electric cars, autonomous vehicles, and related technology, as its aim to push itself to catch up in this critical emerging technology. This is also expected to fuel the regional demand for automotive semiconductors.
