YOUR ROLE

General

·  Manage a cost-effective manufacturing process procedure in wafer fabrication, through the provision of engineering support to the production line, so as to achieve organization's targeted manufacturing index. Take full ownership on all engineering issues of assigned process.
·  Maintain and support day to day manufacturing activities through real-time problem analysis. and real-time solution implementation.
·  Ensure smooth process flow with high quality, high yield, low cost by working with the Maintenance Specialists, Production Supervisors and Shift Engineers to achieve overall committed targets.
·  Provide cross functional/cross-dept/cross-fab support & coverage based on need & priority.
·  Training of new Engineers & imparting technical knowledge to them.
·  Working on shift support as needed and return to normal shift for process project when assigned.

Process

Critical and timely decisions have to be made to ensure risks on Yields, DO, quality, cost, cycle time are minimum.

·  Document & maintain updated specifications on production processes, safety procedures & equipment calibration schedules.
·  Attend shift briefings & address ali process/quality related issues.
·  Support technology transfer and has an ownership to improve process robustness.

Yield

·  Promote and use the tools and methodologies deployed in the company like 'Smart Yield software, teamwork 8D, ESS, Scrap accident reports, Interview report, FMEA and DOE to make the best possible root cause determination and define the best possible permanent preventive action
·  Create and drive teamwork with the Process Engineers (Projects and Engineers on shift), Trainers, Supervisors, Equipment Specialist/ Engineers, Process Control Engineers, QA and Device Engineers, to analyse and resolve fab yield/NCL related problems.
·  Benchmark their methodologies and permanent corrective actions with their peers in other ST Fabs.

Defecttivity

·  Monitor, review and report the defect result analysis after automatic inspection. Minimize tool defectivity excursions and requalification after excursions. Timely disposition of production lots on hold for defectivity issue.
·  Organize team and work with other Process Engineers, Equipment Engineers, Equipment Suppliers etc, to define defect classification and implement permanent fixes after root cause analysis. Participate to the implementation of techniques capable of removing defectivity from the production wafer.
·  Benchmark defectivity result with colleagues from sister Fabs using comparable machines.

SPC

·  Review daily trend on "out of control" excursion, report SPC data of the area according to corporate guidelines and understand the root cause of excursion. Add any Quality task of SPC parameter in order to belted/tighter control of the equipment or the process.
·  Define and enforce deployment of "out of control action plan" OCAP to drive the reduction of parameters standards deviation.
·  Define the action plan to improve the CPK of parameters below the corporately defined CPK value.
·  Participate the weekly SPC meeting and benchmark SPC parameters with the sister Fab area.

Projects

·  • Perform new tool assessment and selection.
·  • Define equipment procurement specification and process acceptance criteria.
·  • Engage with equipment vendor and internal teams on tool procurement, move-in, hook-up and start-up.
·  • Define qualification plan with internal teams and perform tool qualification.
·  • Troubleshoot process and equipment issues with vendors and internal teams.
·  • Perform process and equipment characterization on new tool.
·  • Develop new procedures, control plan, OCAP, FMEA, FDC and conduct training.
·  • Define and implement continuous improvement program to improve process/equipment capabilities, reliability and cost.
·  • Perform process and technology transfer from and to other fabs.
·  • Engage with sending/receiving fab and internal teams on process/equipment matching criteria.
·  • Perform process setup, qualification and characterization.
·  • Troubleshoot process and capabilities issues.
·  • Participate in industrialization program to ensure smooth transition to production.
