Dissolved Oxygen Sensors for Semiconductor Market to Expand at 7.85% CAGR by 2033 Driven by Precision Manufacturing and Ultra-Pure Water Demand

According to a new study by DataHorizzon Research, the Dissolved Oxygen Sensors for Semiconductor Market is projected to grow at a CAGR of 7.85% from 2025 to 2033, driven by rising demand for ultra-pure water (UPW) systems, increasing semiconductor fabrication complexity, and the industry's growing focus on contamination control. As chip manufacturers continue to adopt advanced process nodes, dissolved oxygen monitoring has become essential to ensuring water purity, improving yield rates, and maintaining stringent production standards. The transition toward AI chips, EV components, and high-density memory devices further accelerates the need for highly accurate, real-time oxygen sensing technologies within semiconductor plants.

Market Size & Insights

The global dissolved oxygen sensors market was valued at approximately USD 509.2 million in 2024 and is projected to reach around USD 1,022.89 million by 2033, indicating a compound annual growth rate (CAGR) of 7.85% from 2025 to 2033.

The dissolved oxygen sensors for semiconductor market is experiencing notable growth as semiconductor fabs worldwide prioritize contamination-free water systems to support advanced manufacturing processes. UPW is a core requirement in wafer cleaning, etching, photolithography, CMP (Chemical Mechanical Planarization), and rinsing steps. Even trace levels of dissolved oxygen can compromise surface integrity, leading to oxidation, defects, and reduced yields. As a result, precision oxygen measurement has become a non-negotiable element of fab operations.

Modern dissolved oxygen sensors deliver sub-ppb (parts per billion) accuracy, rapid response times, and compatibility with automated water treatment systems. Their integration into continuous monitoring networks ensures that fabs maintain the highest quality control standards while reducing operational risks. Additionally, as the semiconductor industry transitions toward 3D packaging, heterogeneous integration, and ultra-thin wafer structures, oxygen-free water becomes even more critical for maintaining surface quality.

Growth in sensor demand is also influenced by the global expansion of semiconductor manufacturing capacity. New fabs being established in the U.S., Europe, Japan, South Korea, and Southeast Asia are incorporating state-of-the-art sensing and monitoring technologies from the outset. Increasing investment in smart automation, real-time analytics, and digitalized water systems further enhances the adoption of advanced dissolved oxygen sensors across the semiconductor ecosystem.
