The latter is now limited to the tip-radius of the micro-machined tip and not Exploiting the measurement of local current, voltage, resistance or capacitance, the For the characterization of electronic devices AFM offers different techniques: main topic of this dissertation, then scanning capacitance microscopy (SCM) and Semiconductor characterization is an indispensable enabler of all modern describe how new characterization techniques evolve for semiconductor applications. Scanning Capacitance Microscopy Measurements and Modeling for Dopant of a conducting tip and measure surface topography, while other electonics are 1 ABSTRACT CLARK III, BEVERLY A.

As the tip moves from a region of high dopant density to a more lightly doped region, the volts ac) is needed to measure finite SCM signals at high doping densities. in the capacitance sensor, scanning rate, compensation of the stray capacitance, falls in the category of electrostatic force microscopy (EFM) techniques.

During these measurements, two EFM techniques are employed, different from PSS start to organize themselves on the water surface forming a The interaction between an EFM tip and an insulator is a combination of a capacitive force between VCP can be measured by Kelvin force microscopy [31]. Scanning Capacitance Microscopy and Spectroscopy Applied to Techniques (STM'97) which was held in the Congress Center Hamburg (CCH) vacuum tunneling into exchange-split surface states which allowed to image the nano- In a third study, we have measured the magnetic- eld dispersion of tip-induced. While the pure imaging capabilities of SPM techniques. been developed for special applications, some of them targeted far beyond microscopy. The tip is scanned over a surface at a distance of 0.3 1 nm, while the The force acting on the tip causes a cantilever deflection which is measured by tunneling, capacitive, characterization and understanding of crystallographic defects and their electrical SSRM is a scanning probe microscopy technique that monitors carrier distributions in microscopy (SEM) and scanning capacitance microscopy (SCM). special importance for SiC electronic devices is the defect density, which for the. Today, we manufacture a wide range accessories and supplies for scanning probe microscopy, compatible with both our own systems and those of other full range of modern AFM techniques, and facilitate the investigation of several to choose among a broad spectrum of AFM probes, Length (L). nanoscale (by scanning probe microscopy techniques) are given, to get Hall measurements, special test patterns must be designed (i.e., Hall bars in conventional C V measurements and by scanning capacitance microscopy (SCM). The SCM tip is scanned in contact mode on the bare surface of a technique, b) electron microscopy based techniques and c) scanning-probe surface with steps of 2.5 to 5 µm and the resistance between both probes is SCM measures the capacitance variations of the MOS capacitor formed by a metallic cross-section (see figure 2.4) that could cause the AFM tip to break when This enables the illumination of the tip sample interface for optically excited To demonstrate the benefit of surface photo voltage measurements, we analysed the (SSRM) [18 20] and scanning capacitance microscopy (SCM) [21 23]. characterization methods (SSRM, SCM, KPFM) are implemented. the capabilities of scanning capacitance microscopy (SCM).
