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.

SEMI F19-0185 and Quality Assurance for the Semiconductor Industry

Electropolishing’s ability to remove a microscopically precise layer of surface material – with consistent and repeatable results – is a key reason it is so often specified as the final step in finishing metal parts for industries with no room for error.

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.

Electropolishing for Better, More Durable Plated Parts

While electropolishing is best known for the results it achieves as the last step in the process for finishing critical metal parts, it can also be an interim step for improving the results of parts that will undergo plating.

Biocompatibility and Electropolishing for Medical Manufacturing

The biocompatibility of medical devices, implants and instruments to ensure that every part that comes into contact with the human body poses no risk of irritation or harm is a fundamental requirement for medical manufacturers.

Electropolishing Process with the Highest Standards of Quality Control

For every successful project at Able Electropolishing, there is a meticulous, high-quality process at work behind the scenes.
