Analyze and investigate defect trends / spatial signatures / sleuth and correlate to rogue tool/processes.Assist process and equipment engineers with determining the root cause of the defectivity.Analyze experiment defect data using statistical methods.Perform inking of defectivity to ensure it will not reach the customer.Experienced in FEOL, MOL, and BEOL (over 20 years of process, product/device, and yield enhancement / defect engineering). Have excellent problem-solving skills and am a top investigator, often finding the culprit after other engineers were unsuccessful.Work well with others and am a great team member. Usually ranked near the top. Frequently requested to join various teams as a key member. Have strong verbal and written communication skills.Very knowledgeable with understanding kill ratios of various defects. Experienced in bitmap overlay and generating signature paretos.Generate 8Ds / 3x5 whys / candidate for a Green Belt (Six Sigma).Very experienced with data analysis in Klarity. Also have a lot of experience using JMP, Spotfire, and Excel to analyze data.

Joined the Costello Syndrome Family Network board on June 24, 2013 (volunteer). Became the Vice President on July 19, 2015.Ended June 21, 2021 after hitting the 8 year term limit. I remain active on several committees for CSFN.I most enjoy meeting families of newly diagnosed individuals with Costello syndrome.I remain up-to-date on all publications involving Costello syndrome and share with other families as needed.I help raise money for CSFN to assist in funding the biennial conference as well as research studies.Would entertain a career related to working with individuals and research studies in the medical field. I enjoy working with families to help them understand the medical/research side and to help them advocate for their child. I also enjoy working with data analysis.

Experienced in many roles:Process Engineer for PZT (Lead Zirconate Titanate) toolset for FeRAM program - Ran various experiments, evaluated haze and defectivity, assisted with optimal recipe settings, and ensured preventative maintenance was performed correctly.Product / Device Engineer - Generated yield loss paretos by spatial signature/ tool over a variety of parts. Worked with various process and equipment engineers to reduce yield loss from their toolsets and to help understand single wafer yield loss issues and drive to completion.Yield Enhancement Engineer - Worked with YE engineers, product engineers, and failure analysis engineers to generate bitmap paretos and to understand which defects were driving certain bitmap failures (single bits, double bit columns, full rows, etc.). Moved from K-fab to DMOS6 (300mm factory) to help assist with yield issues. Once they were understood, assisted as a yield enhancement engineer layer owner in the FEOL. Used various data-mining skills to find root causes of defects and drove to understand both defect increases and well as defect decreases.

Started up numerous CVD / Dielectric (SACVD PSG/PECVD/USG) Centura and Producer toolsets at Texas Instruments (200mm / 300mm).Ran experiments to help generate and analyze DOE data to determine the optimal settings for the recipes for the customer's specifications.Provided excellent customer satisfaction and was hired by the customer after unfavorable conditions for Applied Materials led to a very large reduction in force (all 3 CVD engineers were laid off, including those with 10-15 years of experience).

Process Engineer - Learned all aspects of the paper mill from the pulp mill to paper machine to extrusion. Ran various experiments and analyzed the data. Quality Customer Acceptance Supervisor - Supervised the testing associates in the various sections of the mill (pulp, paper, extrusion). Performed investigations for any safety incidents and did performance reviews. In addition, did quality audits to ensure proper testing. Frequently shut down paper machines due to poor quality such as scabs or holes. Also quality checked sizing of rolls to verify they met customer acceptance.
