LG Chem Starts Semiconductor Stripper Materials Production After the Amkor Supply Deal

In July 2026, LG Chem Ltd., a company based in Seoul, South Korea, began the commercial production of semiconductor stripper materials for Amkor Technology Inc. Amkor is a prominent outsourced semiconductor assembly and test (OSAT) manufacturer based in the U.S. This deal represents the debut of LG Chem Inc. in the semiconductor materials manufacturing sector. This deal aligns with the company’s long-term vision of establishing its presence in the semiconductor materials sector.

Semiconductor strippers are chemicals developed specifically to extract the photoresist (PR) layers and leftover contaminants that are on the semiconductor wafers after circuit patterning. Electronic devices are getting more and more sophisticated and sensitive to impurities, which makes the removal of contaminants mandatory. This compels manufacturers to use semiconductor strippers during semiconductor fabrication.

LG Chem has significant technological and manufacturing experience in the digital stripper sector, which helped it to develop capabilities for producing high-quality semiconductor strippers. Amkor Technology Inc. is a prominent semiconductor manufacturing company that has strict quality standards and stringent approval tests. The fact that LG Chem could pass through those tests shows its technical prowess and precise manufacturing ability.

The stripper produced by LG Chem has been specifically designed according to the needs of Amkor. LG Chem claims that its stripper requires around 50 percent less time to decrease photoresist and remove contaminants as compared to conventional strippers. This chemical is expected to decrease production costs, increase the pace of manufacturing, and improve efficiency.

Impact on the Chemicals Industry

According to Precedence Research, the development of semiconductor strippers by LG Chem is expected to benefit the chemicals industry as it provides significant improvement in purifying semiconductor wafers. This development comes at a time when the production of semiconductors is increasing rapidly due to growing demand for electronic devices in various sectors. The demand for electronic systems is increasing in conventional sectors such as smartphones, PCs, TVs, and also in automobiles, industrial machinery, and household appliances, which are rapidly adopting digital and automation technologies.

Impact on the Semiconductor Market

The global semiconductor market size was estimated at USD 627.76 billion in 2025 and is predicted to increase from USD 676.06 billion in 2026 to approximately USD 1,277.45 billion by 2035, expanding at a CAGR of 7.36% from 2026 to 2035.

According to Precedence Research, the semiconductor market is expected to be positively impacted by the development of semiconductor strippers by LG Chem, as it helps semiconductor manufacturing companies use highly effective strippers to clean the wafers in a lesser amount of time. This results in faster and higher-quality production of semiconductors. This is important as the demand for semiconductors is spiking rapidly and the need for very pure semiconductors is also increasing due to increasing complexity and compactness of advanced electronics devices.

Impact on the Semiconductor Wafer Market

The global semiconductor wafer market size is accounted at USD 23.84 billion in 2025 and predicted to increase from USD 25.20 billion in 2026 to approximately USD 41.34 billion by 2035, representing a CAGR of 5.66% from 2026 to 2035.

According to Precedence Research, the semiconductor wafer market is expected to benefit from the debut of LG Chem in commercial production of semiconductor strippers, as it directly helps in their faster cleaning. The cleaned wafers can then be used in further production workflows of semiconductor fabrication.

The company has claimed that its stripper chemicals take around 50 percent less time for wafer cleaning than conventional strippers, which significantly improves the pace of manufacturing. This increases the economic activity in the market as semiconductor fabrication companies can provide semiconductors to electronics companies at a faster rate.

Expert Opinion

According to Kim Dong Choon, the CEO of LG Chem, the joint venture with Amkor Technology is a demonstration of their technological prowess in providing high-quality semiconductor wafer cleaning materials. This displays the company’s dedication to providing good-quality, reliable products which meet the needs of their clients.
