Product development for the Trizact Microreplicated CMP Pad and other pad technologies for polishing applications.
Member of the Chemical Mechanical Planarization (CMP) division, focusing on post-CMP cleaning technologies. Summary of responsibilities: • Development of process solutions to customer's high value problems with respect to post-polish cleans for FEOL and BEOL. • Working on interdisciplinary teams to develop and qualify new hardware and software for CMP tools. Equipment • Reflexion LK and LK Prime tools • Surfscan SP2 and SP5XP Software/Programming • JMP
Summary of responsibilities: • Carried out laser-induced desorption experiments on amorphous solid water systems containing various simple molecule dopants to examine energy transfer and transport in cryogenic thin films using time-of-flight mass spectrometry. • Used FTIR spectroscopy to determine changes within thin films before and after laser radiation. • Carried out TPD experiments with ASW to calibrate thin film dosing methods. • Implemented new experiment protocol that reduced anomalies and improved data-gathering techniques. Techniques • Time-of-flight mass spectrometry (TOFMS) and quadrupole mass spectrometry • Fourier transform infrared (FTIR) spectroscopy • Temperature programmed desorption (TPD) • Atomic force microscopy (AFM) • Basic chemical synthesis (column chromatography, Schlenk line) Equipment • Lasers: extensive work with optics and electronics of Continuum-model Nd:YAG lasers, harmonic generation, stimulated Raman radiation • Ultra-high vacuum (UHV): use and maintenance of mechanical and turbomolecular vacuum pumps Software/Programming • IGOR, MS Office Suite, LaTeX, Adobe Lightroom, EndNote, AutoCAD, HTML/CSS
Course instructor for PHS 1, an introductory physical sciences class for pre-nursing students.
• Provided teaching support for rising college freshman enrolled in a college prep chemistry course that involved lecture and hands-on exploration of concepts. Developed and gave lectures for teaching gas laws, which were accompanied with experiments done in class that demonstrated concepts with household materials.
