Tamer, M.S. (author), van der Lans, M.J. (author), Sadeghian Marnani, H. (author)Image Based Overlay (IBO) measurement is one of the most common techniques used in Integrated Circuit (IC) manufacturing to extract the overlay error values. The overlay error is measured using dedicated overlay targets which are optimized to increase the accuracy and the resolution, but these features are much larger than the IC feature size....conference paper 2018

Yang, G. (author), Guo, P. (author), Procel, P. (author), Weber, A.W. (author), Isabella, O. (author)The poly-Si carrier-selective passivating contacts (CSPCs) parasitically absorb a substantial amount of light, especially in the form of free carrier absorption. To minimize these losses, we developed CSPCs based on oxygen-alloyed poly-Si (poly-SiOx) and deployed them in c-Si solar cells. Transmission electron microscopy analysis indicates the...article 2018

(author)In this work, the macroscopic polarization of a ferroelectric capacitor is correlated with the local domain morphology. To this end, a ferroelectric capacitor of the random copolymer poly(vinylidenefluoride-trifluoroethylene) [P(VDF-TrFE)] is poled to a set polarization state in a Sawyer-Tower setup. After chemically removing the top electrode,...article 2017

(author)In atomic force microscopy (AFM), the exchange and alignment of the AFM cantilever with respect to the optical beam and position-sensitive detector (PSD) are often performed manually. This process is tedious and time consuming, and sometimes damages the cantilever or tip. To increase the throughput of AFM in industrial applications, the ability...article 2017

(author)To date, conventional thermal atomic layer deposition (ALD) has been the method of choice to deposit high-quality Pt thin films grown typically from (MeCp)PtMe3 vapor and O2 gas at 300 °C. Plasma-assisted ALD of Pt using O2 plasma can offer several advantages over thermal ALD, such as faster nucleation and deposition at lower temperatures. In...article 2017
