Purience

Purience is a South Korean technology company specializing in advanced materials and components for the semiconductor industry. Founded in 2022, the company develops and manufactures solutions designed to enhance chip yield and device performance. The firm is headquartered in Daegu, South Korea.

The company's core products include high-purity Polyvinyl Alcohol (PVA) brushes used for post-chemical mechanical planarization (p-CMP) cleaning in semiconductor manufacturing. These brushes are engineered to minimize surface defects and improve particle removal efficiency, leading to higher quality and reliability in integrated circuits. Purience also offers an AI-powered deep learning model to optimize the p-CMP process by analyzing data in real-time to predict component replacement cycles and assist in defect analysis.

Purience serves clients in the semiconductor manufacturing sector. The business model focuses on providing consumable, high-performance components and technology solutions that are integral to the client's manufacturing process. By improving yield and reducing defects, the company provides a direct value proposition to chipmakers. As of early 2024, the privately held company had raised $7.78M in funding.
