Lead wet etch and cleaning formulation development for advanced semiconductor applications.
Responsibilities
- Lead the design and development of wet etch and cleaning formulations for advanced semiconductor materials and process applications.
- Build fundamental understanding of formulation composition, reaction kinetics, selectivity, etch rate, surface condition, residue removal, and materials compatibility.
- Design and execute laboratory studies to screen acids, bases, oxidizers, inhibitors, chelators, surfactants, solvents, and other functional additives while maintaining safe chemical-handling practices.
- Develop and test hypotheses regarding reaction and inhibition mechanisms using analytical characterization, statistically robust experimental designs, and literature or patent review.
- Partner with process and application engineers to evaluate formulation performance using coupons, patterned wafers, and full-wafer tests, and establish correlation across laboratory and wafer-scale results.
Requirements
- MS or PhD in Chemistry, Chemical Engineering, Materials Science, Physical Chemistry, Electrochemistry, Surface Science, or a closely related field.
- Nice to have: simulation modeling
- Nice to have: analytical methods
