Proceedings ArticleDOI
Emerging digital micromirror device (DMD) applications
TL;DR: An overview of past and future DMD performance in the context of new DMD applications is presented, several examples of emerging products are cited, and the DMD components and tools now available to developers are described.
Journal ArticleDOI
Fast, high-resolution atomic force microscopy using a quartz tuning fork as actuator and sensor
TL;DR: In this article, a tuning fork is used as both actuator and sensor of tip-sample interactions in an atomic force microscope (AFM) to measure the tip sample distance.
Journal ArticleDOI
Insitu spectral ellipsometry for real-time measurement and control
Walter M. Duncan,Steven A. Henck +1 more
TL;DR: In this paper, a spectral ellipsometer was designed and built specifically for adaptive control in single wafer processing, which is capable of precisely measuring thicknesses and compositions of multilayer structures in situ and in real time.

Scanning-probe microscope including non-optical means for detecting normal tip-sample interactions
Hal Edwards,Walter M. Duncan +1 more
TL;DR: In this article, a scanning-probe microscope for measuring the topography of a surface of a sample is described, consisting of an XYZ piezo drive (piezo drive 1); a quartz tuning-fork oscillator (fork 2); and a probe tip (probe tip 6) affixed to one of the tines, the probe tip comes to a point in the Z direction and directed away from the XYZ PIZ drive.
Journal ArticleDOI
Atomic layer epitaxy of GaInP ordered alloy
B. T. McDermott,Kimberly G. Reid,Nadia A. El-Masry,Salah M. Bedair,Walter M. Duncan,X. Yin,Fred H. Pollak +6 more
TL;DR: In this article, the growth of ordered GaInP by atomic layer epitaxy on a GaAs substrate was reported, and the growth was achieved by alternate exposures to TEI, PH3, TMGa, and PH3 fluxes, and epilayers were found to closely match the substrate irrespective of the growth conditions.
