About me
Professional optomechanical design engineer offering over ten years experience in design of mechanical and optomechanical systems used in capital semiconductor equipment and precision engineering.
Deep understanding and hands on experience applying GD&T standards, Gauge R&R, DoE, dimensional and geometrical metrology.
Over ten years experience in creating CAD models, assemblies, FEA, CFD, and blue prints. Also, I strictly follow DFM, DFA, and DFX guidelines. I offer an extensive experience in designing high precision machines and fluency in using CAD packages such as Solidworks® , Siemens NX®, and ProE®.
Excellent team player with high organizational and multitasking skills.
HIGHLIGHTS OF CAREER ACHIEVEMENTS
- Developing UHV system at KLA.
- Developing mechanical designs of assemblies for the new synchrotron at Lawrence Berkeley National Laboratory (LBNL).
- Opto-mechanical design of key assemblies to be used in the new KLA’s mask inspection capital equipment.
- Improved the design of mechanical and opto-mechanical assemblies in the next generation lithography system in Ultratech-Veeco.
- Developed high efficiency cooling method of high power mercury lamps (2KW) at Ultratech (Veeco)
- CAD models, assemblies, GD&T , 2D drawings, FEA analysis, CFD analysis and bolt calculations.
- Introduced, designed, and applied a state-of-the-art metrology method and tools to align mechanical and optomechanical subsystems inside the lithography machine at Ultratech-Veeco. These tools (to be patent soon) also confirm the right distances and relative positions between many optical components.
- Designed a fiber connection module and improved the design of an opto-mechanical module used in the next generation leveling sensor in ASML lithography machine (TWINSCAN™).
- Designed fixtures necessary for vibration analysis and shock testing of optomechanical modules to be used in next generation ASML TWINSCAN™.
- Designed, assembled and tested Wafer Transfer Stage which is a critical module in KLA-Tencor SURFSCAN™ new generation.
- Designed, assembled and tested Plasmonic Nanolithography Machine.
- Developed optical measuring system to measure the Coefficient of Thermal Expansion of ball bar (used for calibration CMMs).
- Developed a binary Morphological Image Processing (MIP) approach to assess surface texture of engineering surfaces.
- Developed an image stitching method to measure surface profile of large hemisphere using WLI.
- Developed a Starter Bibliography for Surface Metrology presented at ASME B46.
- Teaching undergraduate mechanical engineering students for 10 years.
