Precise Surface Finish in Semi-Polished Plates

Surface finish in stainless plate fabrication for semiconductor tooling and microchip equipment requires polishing tolerances. When measuring the surface, AAA Metals Co., Inc. utilizes several different techniques to achieve precise surface measurements.

Why Surface Finish Matters in Semiconductor Equipment

Surface finishes play an essential role in the performance, yield, and quality of machine parts used in semiconductor manufacturing. As technology becomes smaller and more advanced, the specifications of a silicon wafer have become stricter.

The following surface parameters must be taken into consideration:

  • Uniformity
  • Smoothness
  • Absence of irregularities

The Connection Between Surface Integrity and Yield

Surface specifications must meet stringent requirements to promote the highest level of reliability, performance, and quality.

The surface integrity must be maintained during every step of the fabrication process to allow for the highest yield rates while delivering:

  • Accurate focus
  • Dimension control
  • Uniform layer thickness

These properties are essential for manufacturing high-density circuits, advanced semiconductor components (such as memory chips and microprocessors), and machine parts used in semiconductor manufacturing. They are also critical for producing solar cells, integrated circuits, and other photonic and electronic devices.

Finishing Methods Used To Achieve Ultra-Precise Results

Various stainless steel polishing, metrology, and grinding methods can be used to achieve and maintain desired specifications, such as:

  • Dimensional testing. Measures and verifies the geometric properties of machine parts to ensure they meet tight tolerance and design specifications.
  • Mechanical grinding. A rotating wheel removes excess material to prepare, shape, or finish a surface with high precision.
  • Stainless steel polishing. Smooths the surfaces of angles, pipes, sheets, and other fabricated metal pieces, providing a final corrosion-resistant finish.
