Work History

Senior Manager (Probe Equipment)

Micron Semiconductor
11.2021 - Current
  • Provided strong leadership to enhance team productivity and morale. Lead and manage a team of around 100 employees over 3 physical production area.
  • Achieved >10% manhours saving within 1st year through implementation of total productive maintenance methodologies to improve efficiency and productivity. (Consistent > 10% improvement YOY).
  • Managing spares and repair budget of ~ USD $5M, track record of consistent > 15% cost reduction every year through effective inventory management and cost improvement projects
  • Led cross-functional teams to achieve project milestones and deliver high-quality results. For example, Breakthrough in AGV loading percent from ~50% to 99% and 50% reduction in loss time for all functional test workstation.

Manager (Probe equipment)

Micron Semiconductor
02.2021 - 11.2021
  • Managed and motivated a team of over 80 shift equipment technicians and engineers to be productive and engaged in work.
  • Within 1 year taking over the team, achieved more than 10 times increase in Total Preventive Maintenance (TPM) project submission from the team through empowering and supporting team members to propose solutions or improvement item to overcome inefficiencies faced.
  • Enabled USD $14M tool purchase avoidance by redesigning probe tool robot arm (USD $2M) and, at the same time, improved productivity through vacuum error elimination

Shift Manufacturing Manager

Micron Semiconductor
12.2018 - 02.2021

Accomplishments

Managing cross functional group projects:

1. Site lead for F10 for global program like CheckM, change point monitoring:

Key involvement in project development through input on user requirement, testing and modification.

Successfully implementation of CheckM and achieving consistent >99.3% compliance to change point monitoring across all areas in F10N.


2. Department lead for TPM MPEO for F10N MFG:

· Strategize and achieve >40% manual touch reduction for F10N MFG since embarking on the MPEO program in WW10 2019.

· Outstanding increase the TPM project submission from F10N shift production in response to the MPEO and labor productivity program (from 50 per year)


3. Module lead for F10 labor productivity program.

· Leading shift production to meet HC saving target as part of labor productivity program.

· Achieved > 30 HC saving for FY20


Enabling breakthroughs in operation improvement projects:

1. Eliminate loader arm vacuum error (as high as 250 count per week) through collaboration with vendor to redesign arm. Through close collaboration with cross functional team, obtained the USD $2M funding required to replace arm for all tools and achieve USD $14M saving through tool purchase avoidance.


2. Spearhead RPA implementation program in Micron F10.

· Successfully deployed RPA to replace manual operation in

i. Merge request (~1k lots merge by RPA per week)

ii. DE and CMP RDA request (~800 request per week)

iii. Auto release lots on hold due to multiple lot in FOUP staged to different tool (~1k per week)

iv. PH resist mat req (eliminate need to manual raise mat req)


3. Drive 20% YOY productivity improvement through in-depth understanding of operation efficiency, with key collaboration like CVD process Post Recovery Attribute Tagging Automation (PRATA) to reduce ~700 manual touches per week in tagging attribute.
