Abstract Owing to the advancing progress of electrical measurements using SEM (Scanning Electron Microscope) or AFM (Atomic Force Microscope) based nanoprober systems on nanoscale devices in the modern semiconductor laboratory, we already have the capability to apply DC sweep for quasi-static I-V (Current-Voltage), high speed pulsing waveform for the dynamic I-V, and AC imposed for C-V (Capacitance-Voltage) analysis to the MOS devices. The available frequency is up to 100MHz at the current techniques. The specification of pulsed falling/rising time is around 10-1ns and the measurable capacitance can be available down to 50aF, for the nano-dimension down to 14nm. The mechanisms of dynamic applications are somewhat deeper than quasi-static current-voltage analysis. Regarding the operation, it is complicated for pulsing function but much easy for C-V. The effective FA (Failure Analysis) applications include the detection of resistive gate and analysis for abnormal channel doping issue.

Abstract A contact probing system for surface imaging and real-time signal measurement of deep sub-micron integrated circuits is discussed. The probe fits on a standard probe-station and utilizes a conductive atomic force microscope tip to rapidly measure the surface topography and acquire real-time highfrequency signals from features as small as 0.18 micron. The micromachined probe structure minimizes parasitic coupling and the probe achieves a bandwidth greater than 3 GHz, with a capacitive loading of less than 120 fF. High-resolution images of submicron structures and waveforms acquired from high-speed devices are presented.

Разработка высокоэффективных режимов быстродействующего сканирующего зондового микроскопа, в первую очередь атомно-силовой и сканирующей капиллярной микроскопии, представляет особый интерес для успешного проведения биомедицинских исследований: изучения биологических процессов и морфологии биополимеров, определения антибио­тикорезистентности бактерий, адресной доставки биомакромолекул, скринингу лекарств, раннему обнаружению биологических агентов (вирусов и бактерий) и др. The development of highly efficient modes of a high-speed scanning probe microscope, primarily atomic force and scanning capillary microscopy, is of particular interest for successful biomedical research: studying biological processes and the morphology of biopolymers, determining antibiotic resistance of bacteria, targeted delivery of biomacromolecules, drug screening, early detection agents (viruses and bacteria), etc.
