Experience

Micron Technology, Manassas VA, September 2007 - October 2008

Wet Process Shift Engineer 2 - 300mm Wafer FAB.
  • Direct and sustain process improvements using SPC.
  • Strategically identify and analyze process failures.
  • Audit process recipes, configure hardware, and use procedural methods to perform process enhancements.
  • Identifying, understanding, and resolving defect issues, assisting area technicians troubleshooting problems, improving preventative maintenance procedures, and optimizing overall tool performance.
  • Proficiency across all wet process modules and toolsets is necessary in order to be able to disposition lots efficiently, prevent scrap and continuously improve wet process capabilities.
  • Process Modules and tool sets include: Wet Benches (Tel and DNS Electronics FC-3000, FC-3100), Ash and Descum (Axcelis - Rapid Strip), Single wafer processing, Nanospray and Scrub (SCREEN - DNS, SU-3000, SS-3000), Cu Plating (Semitool - Raider), Dry Bevel Etch (Sosul)

Projects

50 Series NAND Redundancy Project.
Create redundancy for clean process steps across all wet process toolsets in anticipation for wafer processing ramp.

AMI Semiconductor, Pocatello ID, January 2006 – January 2007

Primary process engineer for Metal Deposition and Rapid Thermal Processing.
  • Worked directly with production and the engineering team to review existing procedures and to identify and implement cost, quality and productivity improvements.
  • Oriented in statistical analysis i.e. DOE, SPC and process capability.
  • Tool set: MRC, Heat Pulse 8108 Rapid Thermal Processor.
  • Responsibilities included sustaining, data analysis, continuous improvement of current procedures, cost savings, new process introduction.

Projects

ARO (Automatic Roll Off) table development and optimization
  • Successfully implemented tables for AlSiCu target chambers on MRC metal sputtering tools that accounted for the unique deposition behavior of each.
  • Modified specification procedures and provided training.
  • Productivity was increased while human intervention and tool downtime was minimized by successfully eliminating time changes.
Metal particle reduction project
  • Restructured Metal deposition paste cycles completely in order to reduce particle counts and improve defect density D0.
  • Implemented periodic Process Switching (AlSiCu-TiW) for maximum tool performance.
  • Reduced cost by eliminated thick aluminum paste.
AlSiCu Target Characterization
  • Directed split lot experiments to qualify lower cost AlSiCu target vendor to be used in MRC sputtering tools.
  • Performed test statistics in MAP test parameters.
Project to move Implant Omnis from Diffusion to RTP
  • Optimized RTP Recipe.
