Verify that all etching equipment, including nitric acid handling systems, is in proper working order before operation• Perform Nitric rinse tank changeovers per work instructions• Operate both manual and automated wet etching processes to exact specifications• Monitor process parameters such as temperature, flow rates, and chemical concentration to maintain consistent etch quality• Use inspection tools (e.g., microscopes, thickness measurement systems) to verify critical dimensions and etch quality• Inspect substrates for photoresist quality before etching and after etching to ensure no defects• Perform tape tests or other inspections to confirm complete and uniform etching• Strip photoresist from substrates and inspect for cleanliness• Perform routine maintenance on etching equipment and related systems• Troubleshoot process issues, such as incomplete etches or contamination, and implement corrective actions• Log maintenance activities and report equipment problems to supervisors.• However, employees who have access to the compensation information of other employees or applicants as a part of their essential job functions cannot disclose the pay of other employees or applicants to individuals who do not otherwise have access to compensation information, unless the disclosure is (a) in response to a formal complaint or charge, (b) in furtherance of an investigation, proceeding, hearing, or action, including an investigation conducted by the employer, or (c) consistent with the contractor's legal duty to furnish information.
