COVID-19 Impact

The outbreak of the COVID-19 pandemic took a severe toll on the global supply chain and subsequently led to raw material shortages and price escalations. Several industries and industry verticals were affected by the shortage of raw materials, and the semiconductors industry was not an exception. The demand for semiconductors increased significantly in line with the growing demand for electronics as businesses opted for remote working, consumers tried to brace themselves for the new, work-from-the-home trend, and internet service providers (ISPs) tried aggressively to strengthen internet connectivity.

Businesses involved in manufacturing activities mainly opted for manufacturing and production solutions based on IoT technology and smart devices to facilitate remote operations and monitoring. However, the supply of semiconductors was unable to keep up with the growing demand as fabrication centers or foundries were already running close to capacity or experiencing staffing problems as a result of the outbreak of the pandemic.

As a result, the supply of semiconductors continued to plummet when the demand showed no signs of abating. Looking forward, the demand-supply imbalances will take longer to resolve until the disrupted supply chains restore wholly and both raw material supplies and production levels resume the pre-pandemic levels.

Among these segments, the ball grid array packaging segment dominated the market in 2022, capturing a revenue share of 28.3%. Ball grid array (BGA) packaging is an integrated circuit surface-mount packaging type that has become a preferred option for high I/O devices due to its several benefits over traditional large lead count packages. It reduces handling issues and placement problems during packaging and is used for installing electronics like microprocessors permanently.

BGA packaging can accommodate more connectivity pins than dual in-line or flat packages by using the entire bottom surface of the gadget. Meanwhile, the multi-chip packaging segment is projected to experience the highest growth, with a CAGR of 9.2% throughout the forecast period. Multi-chip packaging (MCP) is a system-in-package that combines multiple integrated circuits into a single device. MCP comes in different types, including multi-chip module plastic laminate (MCM-L), multi-chip module ceramic (MCM-C) thin film, and multi-chip module deposited (MCM-D) thin film, depending on the designer's development and complexity requirements.

An essential feature of MCP is that it utilizes standard packages as a vehicle for minimal multi-chip module (MCM) applications. End-users can quickly implement MCP since the test, handling, and installation equipment is already available in the industry. MCM technology has been utilized in products such as the Intel Pentium Pro, IBM Bubble memory MCMs, Xeon Dempsey, Pentium D Presler, Clovertown, and Sony memory sticks.

The testing segment is anticipated to grow at a faster rate, at a CAGR of 9.8% throughout the forecast period. Semiconductor testing is a vital component of the production process, particularly as Integrated Circuit (IC) architectures become increasingly sophisticated and the focus on optimizing time-to-market increases.
