62. Limitations of the Calibration Curve Method for Determining Dopant Profiles from Scanning Capacitance Microscope Measurements
Published: 3/1/2000
Authors: Jay F. Marchiando, Joseph J Kopanski, John Albers
Abstract: The calibration or conversion curve method (CCM) refers here to using a database of calculations of the capacitance done for a matrix set of model parameters, such as oxide thickness, uniform dopant density, etc., as one method for interpreting scann ...

63. Carrier Concentration Dependence of Scanning Capacitance Microscopy Signal in the Vicinity of P-N Junctions
Published: 1/1/2000
Authors: Joseph J Kopanski, Jay F. Marchiando, Brian G. Rennex
Abstract: Scanning capacitance microscopy was used to image 1) boron dopant gradients in p-type silicon, and 2) identical boron dopant gradients in n-type silicon. The bias voltage dependence of the apparent p-n junction location in the SCM images was measure ...

66. Dopant Characterization Round-Robin Study Performed on Two-Dimensional Test Structures Fabricated at Texas Instruments
Published: 12/31/1998
Authors: J. Vahakangas, Markku Lahti, M C Chang, H Edward, C F Machala, R S Martin, V Zavyalov, J S McMurray, C. C. Williams, P DeWolf, Vandevorst, D. Venables, S S Neogi, D L Ottaviani, Joseph J Kopanski, J F Machiando, Brian G. Rennex, J N Nxulamo, Y Li, D J Thomson
Abstract: The lack of a two-dimensional (2D) dopant standard, and hence, a priori knowledge of dopant distribution makes it impossible to unambiguously judge accuracy of any experimental or theoretical effort to characterize silicon doping in two dimensions. R ...

68. Comparison of Measured and Modeled Scanning Capacitance Microscopy Images Across P-N Junctions
Published: 7/1/1998
Authors: Joseph J Kopanski, Jay F. Marchiando, John Albers, Brian G. Rennex
Abstract: Scanning capacitance microscope (SCM) image contrast measured on ion implanted P^u+^/P and P^u+^/N junction structures with identical dopant profiles, as a function of SCM operating conditions, is compared to a theoretical model of the SCM based on a ...

69. Intermittent-Contact Scanning Capacitance Microscope for Lithographic Overlay Measurement
Published: 5/11/1998
Authors: Joseph J Kopanski, Santos D Mayo
Abstract: A new scanning capacitance microscope (SCM) mode was implemented by using an atomic force microscope (AFM) operated in intermittent contact and by measuring the tip-to-sample capacitance change at the tip vibration frequency. The intermittent-contac ...
