SEMI P12 - Determination of Iron, Zinc, Calcium, Magnesium, Copper, Boron, Aluminum, Chromium, Manganese, and Nickel in Positive Photoresists by Inductively Coupled Plasma Emission Spectroscopy (ICP)
NOTICE: This Standard or Safety Guideline has an Inactive Status because the conditions to maintain Current Status have not been met. Inactive Standards or Safety Guidelines are available from SEMI and continue to be valid for use.
This procedure is an ICP plasma emission analysis for determination of iron, zinc, calcium, magnesium, copper, boron, aluminum, chromium, manganese, and nickel in photoresist. The applicable concentration range is 0.1 to 1 ppm when the sample is diluted 1 to 4. The precision was found to be within 0.1 ppm in a round robin analysis between four laboratories.
