April 7, 2005
Author(s)
C E. Cox, Daniel A. Fischer, W G. Schwarz, Y Song
Soft X-ray beam-line applications are of fundamental importance to material research, and commonly employ high-resolution Si(Li) detectors for Energy Dispersive Spectroscopy. However, the measurement of X-rays below 1 keV compromised by absorption in the

Photomask Feature Metrology

April 7, 2005
Author(s)
James E. Potzick
This chapter discusses some general issues with regard to measurement of the size and placement of the features on a photomask.
Since all linewidth and placement measurements derive from the location of a feature's edges, the Chapter starts with a

Reaction gas chromatography/mass spectrometry. 2the use of catalytic on-line dehydrogenation for the investigation of alcohols by gas chromatography/mass spectrometry

April 7, 2005
Author(s)
Anzor I. Mikaia, Vladimir Smetanin, Vladimir G. Zaikin, Alla V. Antonova, Nikolay A. Prostakov
A GC-MS method is developed for structure determination of aliphatic within mixtures. It involves online application of a gas-phase dehydrogenation reaction after GC separation and before MS analysis. Primary and secondary alcohols are converted into

Elastic-property measurements of ultrathin films using atomic force acoustic microscopy

April 5, 2005
Author(s)
Malgorzata Kopycinska-Mueller, Roy H. Geiss, Jens Mueller, Donna C. Hurley
Atomic force acoustic microscopy (AFAM), an emerging technique that affords nanoscale lateral and depth resolution, was employed to measure the elastic properties of ultrathin films. In this study we measured the indentation modulus M of three nickel films
