Lewis University, Pall Corporation announced that scientists from both organizations have expanded research into optimizing filtration technology for chemical mechanical planarization (CMP) operations, a critical step in the manufacture of microchips. With the advent of new slurries containing ever finer nanoparticles, filtration is critical to removing oversized, defect-causing particles while allowing the unhindered passage of the active, small particles. The study was designed to elucidate differences in adsorption characteristics of silica and ceria particles, which are common abrasives in CMP slurry, to filter media. The results can provide guidance when designing filtration for specific slurry types, or when recommending specific filter grades or modes of usage in order to maximize filtration efficiency and service life.

Lewis University has entered into a new 11-year lease agreement and will relocate the Oak Brook Campus from its current location on York Road to 1111 W. 22nd Street in Oak Brook in time for Spring 2013 classes. Lewis University Oak Brook Campus plans to occupy the entire 7th floor at 1111 W. 22nd and the build out for the new space will begin in Fall 2012. Space will double from the existing 15,000 sq. ft. of classrooms, conference rooms, offices and a computer lab to 28,360 sq. ft. of classrooms, conference rooms, offices, computer labs and a specialized lab for the College of Nursing and Health Professions Adult and Family Nurse Practitioner programs. The new facility offers a parking garage and is immediately accessible from major toll ways and 22nd Street in Oak Brook.
