IBM, Hopewell Junction, New York (February 2010 - Present)
Title: PLY (Process Limiting Yield) Characterization Engineer
Responsibilities:
. Define/refine inspection strategies to maximize yield
learning, while not exceeding inspection time targets to
ensure containment within the inline inspection capacity
plan.
. Provide defect characterization reporting for new
technologies to improve yield, performance and reliability.
. Deliver yield paretos of key defect mechanisms and drive
closure on same with the technical community
. Deliver timely, accurate identification of trends (with
vintaging, tool analysis, etc) to assist in root cause
analysis. Identify and summarize key statistics and trends.
Characterize window/trade-offs between process stability and
performance Summarize results in a clear and concise format.
. Establish/Leverage Early Product Yield Learning vehicle(s) in
preparation of their transfer to manufacturing
. Support the qualification activities and technology
milestones and work with integration as well as process
module teams to provide timely feedback on split/process
experiments, tool quals, etc.
. Identify any yield modulation between splits and identify
process improvements.
Major Projects Highlights:
. Implementation of SSA(Spatial Signature Analysis):
. Successfully programmed and implemented SSA algorithms to
automate the detections of scratches and other macro
signatures on the wafer and generate immediate notification
to tool owners reducing the response time to yield
incursions.
. Evaluated all existing Final Wafer inspection recipes and
suggested improvements to minimize false detections which
were masking critical failure signatures.
. Identified, isolated and eliminated failure mechanisms
which were causing scraps during final wafer inspection.

July 2009)
Title: Yield Engineer
Responsibilities:
. Acted as a lead engineer for KLA-Tencor AIT, KLA-Tencor
EV300, Rudolph NSX defect inspection tools and fully
qualified substitute engineer for KLA-Tencor KLA-2139, KLA-
Tencor Surfscan SP1 toolsets.
. Designed process experiments to understand and eliminate
yield loss mechanisms. Interacted with manufacturing,
development, and Failure Analysis Team to influence prompt
executing of appropriate corrective actions.
. Established routine inspection procedures to optimize
visibility of yield related excursions and continuously
revised frequency of short term inspection procedures to
avoid redundant inspections.
. Monitored inline defect performance using Statistical Process
Control (SPC) and develop/coordinate out of control action
plans, in compliance to Six Sigma Process Controls. Generated
work orders for unscheduled PM (Preventive Maintenance) tasks
based on tool specific defect trends.
. Analyzed inline electrical tests results against established
defect density targets to characterize the current process of
record (POR). Correlated FM (Foreign Material)
classifications codes to Electrical loss parameters at Final
Test to generate updated yield projections.
. Identified and documented major yield issues and provided
weekly updates to senior management to prioritize capital and
resource allocation.

Major Projects Highlights:
. Development of Refined Broken Wafer Cleaning/Inspection
Procedure:
. Redeveloped and streamlined NXP Fishkill broken wafer
cleaning and inspection procedures to reduce unnecessary
scrap losses which were traditionally a great source of
lost revenue.
. Worked closely with WETS process engineer to eliminate non-
value-added cleaning operation and introduce backside brush
clean before batch cleaning.
. Retooled defect classification codes for broken wafer
inspections based on process level so that their defect
kill-factor ratio correlates with the Final Test electrical
testing.
. Proposed changed to broken wafer cleaning and inspection
were accepted by site TRB (Technical Review Board)
resulting 50% reduction in broken wafer scraps evaluated
over last year with no associated losses in Final Test
electrical yield or reliability stress test results.
. Implementation of Automated Final Wafer Inspections at NXP
Fishkill using Rudolph NSX:
. Proposed and administered the introduction of Rudolph NSX

sorting of inspection data history based on job runtime
history saving considerable engineering hours wasted in
data mining.
