Electropolishing & Microfinishing for the Semiconductor Industry

Semiconductors are essential components in today’s electronics and technology industry. Electropolishing is commonly used as a final step for metal parts utilized in these applications to create an ultraclean surface that resists corrosion and adheres to strict dimension requirements.

How We Work with Semiconductor Clients

FINISH FIRST: Electropolishing in the R&D Process

Our Finish First methodology enables world class design and manufacturing engineers to approach metal finishing challenges from the beginning, both as a way to ensure better results prior to penetrant testing, and as an advantage in the design and prototyping stage.

Meeting Specifications for Semiconductors with Electropolishing

The semiconductor industry has some of the most demanding surface finish requirements of any industry that uses our services. Due to the corrosive nature of the liquids and gases used in the manufacturing processes, the industry has developed rigid specifications for acceptable finish quality. Able’s processes meet these specifications, including SEMI F19, which defines the wetted surface characterization requirements and finish acceptance criteria for electropolished 316L stainless steel components.

Able Electropolishing works with companies who manufacture components for the semiconductor industry. One of our customers sends a family of custom 316L SS fittings used in the chemical distribution systems of semiconductor manufacturing facilities. The wetted surfaces require a 10 Ra microinch finish, or better, after electropolishing. In addition, the chromium to iron ratio must be a minimum of 1.5:1 and a chromium oxide enrichment of a minimum chromium oxide to iron oxide ratio of 2:1. The results are verified through optical examination, ESCA, Auger and SEM analyses.

Compared to passivation alone, electropolishing is 30 times more effective for improving corrosion resistance. Send your samples for electropolishing and we will evaluate both finish and dimensional changes. If electropolishing is planned during the design stage, the material removal can be factored into your final size specifications.
