91. Height Calibration of Atomic Force Microscopes Using Silicon Atomic Step Artifacts
Published: 1/1/1996
Authors: V W. Tsai, Theodore Vincent Vorburger, P Sullivan, Ronald G Dixson, Richard M Silver, Edwin Ross Williams, J Schneir
Abstract: The decreasing feature dimensions required in the semiconductor manufacturing industry are placing ever increasing demands upon metrology instruments. Atomic force microscopes (AFMs), which can have ~1 nm lateral resolution and sub-angstrom vertical ...

92. Optical Overlay Metrology at NIST
Published: 1/1/1996
Authors: Richard M Silver, Amy Singer, L Carroll, S Berg-cross, James Edward Potzick
Abstract: Many of the significant challenges in making accurate overlay registration measurements are discussed. An understanding of the causes of the errors affecting these measurements is a prerequisite to improving accuracy and also for the design of standa ...

94. Delineation of pn Junctions by Scanning Tunneling Microscopy/Spectroscopy in Air and Ultrahigh Vacuum
Published: 5/1/1995
Authors: Richard M Silver, John A. Dagata, H. W. Tseng
Abstract: Lateral dopant profiling of cleaved, passivated abrupt GaAs pn junctions using scanning tunneling microscopy/spectroscopy is demonstrated both in ultrahigh vacuum and air. A combination of forward-and reverse-bias imaging and position-dependent tunn ...

95. Metrology with the Ultraviolet Scanning Transmission Microscope
Published: 5/1/1995
Authors: Richard M Silver, James Edward Potzick, Y Hu
Abstract: A novel design for an ultraviolet critical dimension measurement transmission microscope utilizing the Stewart platform as the rigid main structure has been implemented. This new design shows improved vibration characteristics and is able to accommod ...

96. Overlay Measurements and Standards
Published: 5/1/1995
Authors: Richard M Silver, James Edward Potzick, Robert D. Larrabee
Abstract: The relative misalignment of features produced by different mask levels (i.e., overlay error) is projected to become an increasingly important problem to the semiconductor industry as the size of the critical features continues to decrease. In respon ...

98. Ambient and Vacuum Scanning Tunneling Spectroscopy of Sulfur and Oxygen-Terminated Gallium Arsenide
Published: 11/1/1994
Authors: Richard M Silver, John A. Dagata, H. W. Tseng
Abstract: Tunneling spectroscopy of sulfur- and oxygen-terminated n- and p-type GaAs (110) surfaces is reported for air and ultrahigh-vacuum conditions. Simulations of the complete I-V characteristics with explicit inclusion of surface states within the planar ...
