PHOTOLITHOGRAPHY PROCESS ENGINEER/METROLOGY APPLICATION ENGINEER
Twenty years of experience in photolithography area as process and metrology engineer with strong skills in overlay and CD-SEM tools and automatic process control. Strong industrial engineering skills and management of production processes.
Experience in SPC and APC using Run-to-Run feedback technique, sampling and analysis of measurement systems (MSA), integrated process and controlled conversion of production processes.
Proven skills in Project Management, Process Mapping e Business Process Improvement. Throughout my professional career, I worked also to manage and define the operating procedures for quality using the Lean-Six-Sigma principles and monitor the external audit ensuring the correct alignment with the standards prescribed by the ISO 9001 and ISO-TS 16949 requirements, and managing any non-compliance. Interested in evaluating proposals for semiconductor industrial environments as well as in the design company and available for transfering in Europe.
Developed an Automatic Process Control for overlay compensation based on a Run to Run model and an adaptive Esponential Weigthed Moving Average algorithm
Developed a buissness process for the in-line sample, maximizing the metrology tools utilization while minimizing the risk of an non detected OOS for product.
Developed a statistical analysis tool for CD SEM tool, VBA excel based
Designed and developed a relational database in MS Access for CD-SEM recipe setup data collection
Statistical process control
CD SEM metrology
Process Business Improvement

In my current role I am working on BKM and continuous improvement for the measurement techniquesì and reliability, quality assurance.
Responsible for defining the "scribe lane" standardization, in particular for the CD-SEM measurement structures.
Project for analysis, reduction and predicibility of cycle time of prototype under development (just-in-time shipment to the customer), with DMAIC approach as per the Lean Six-Sigma quality discipline.
Responsible for APC (automated process control) parameters optimization and its improvement.
Project and development of a relational database to collect the metrology setup data necessary to run the first silicon of the NTI/NPI devices.
Applied BPI/BPM methdologies to different internal processes of the area.
Project management: collaboration with R&D department for the study of the OPC (Optical Proximity Correction) modeling, in order to enhance the optical resolution required for the 90 nm technology node.

Senior process engineer / Lead engineerMicron Technology Italia S.r.l
reporting to the Section Manager and supervisor of 13 people Partecipate in process transfer activity from other facilities (SDRAM devices) From Jan 1999, metrology and process engineer in shift working on CD-SEM, overlay tools, stepper CANON iline and ASML DUV scanner pas 800 tools.
Four years experience as lead engineer in shift, supervisor of a team of 13 people.
The team was responsible for equipment preventive maintenance activities, equipment uptime and quick reaction to fails, process development of new devices, SPC control, detection of process escursion and disposition of deviant material, DOE execution, follow up on safety requirements.
Safety, feedback communication, performance review, and training plan development was my main activities related to supervisor role.
In 2003, I was promoted and moved back to daily shift as CD SEM technology expert.
My main responsibilities was: Schedule preventive maintenance and equipment performance analysis (up-time, lost time, eng time, spare parts management, etc.) Follow up on new tools installation Operative procedure definition for BKM recipe making and equipment maintenance MSA (measurement system analysis) champion for ISO-TS 16949 compliance Sample champion for the dinamic sampling process efficiency Training and coaching to new hired Concept and realization of a new automatic control system, a Run-to-Run technique based on an adaptive Exponential Weigthed Moving Average algorithm.
Also, an additional algorithms to overcome the unefficiency due to the batch run was developed, as well as for start and stop material in production line.
Project management to convert the installed base of CD-SEM tools from KLA8100 to AMAT Verity SEM model.
Project execution of the best sample process following the business process management method.
Member of a project team for the double exposure technique for imager CMOS devices development.
Apply the what-if and decision-analysis methodologies to resolve a capacity problem.
The achieved goal was to avoid to buy a new CD SEM tool, getting 1.5 milion $ of cost saving.
