AES Analysis of Al Bond Pads in Electrically Insulating Surroundings Utilizing Metal Grid Contacting

  title={AES Analysis of Al Bond Pads in Electrically Insulating Surroundings Utilizing Metal Grid Contacting},
  author={Uwe Scheithauer},
: Bond pads are the electrical interconnections of a microelectronic device to the ‘outside world’. A polyimide (PI) layer on top of a microelectronic device protects the whole device against environmental impacts. The bond pads are accessible though openings in this electrically insulating layer. The oxide layer thickness and contaminations at the Al bond pad surface influence as well the quality of the mechanical and electrical joint between bond pad and bond wire as the durability of this…

Status monitoring of ion sputter relevant parameters of an XPS depth profiling instrument
An X‐ray photoelectron spectroscopy (XPS) instrument is utilized for sputter depth profiling of thin films. Relevant instrumental parameters are the ion gun sputter rate, the contamination level of
The Benefit of Wide Energy Range Spectrum Acquisition During Sputter Depth Profile Measurements
Thin film systems are often analysed by using sputter depth profiling. First the sample gets eroded by inert gas ion impact during sputter depth profiling. Then the elemental composition of the
Reducing non-stick on pad for wire bond: A review
Abstract One of the largest losses in semiconductor assembly operations is non-stick on pad (NSOP) failures. NSOP failures are costly as the entire device will need to be rejected if there is one
Quantitative electron spectroscopy of surfaces: A standard data base for electron inelastic mean free paths in solids
A compilation is presented of all published measurements of electron inelastic mean free path lengths in solids for energies in the range 0–10 000 eV above the Fermi level. For analysis, the
Surface charge neutralization of insulating samples in x-ray photoemission spectroscopy
Obtaining high resolution x-ray photoemission spectroscopy (XPS) spectra of insulating samples has long been a problem because of difficulty controlling sample surface potentials. A flood of low
Application of the analytical methods REM/EDX, AES and SNMS to a chlorine induced aluminium corrosion
SummaryScanning electron microscopy (SEM) with energy dispersive X-ray detection (EDX), Auger electron spectroscopy (AES) and sputtered neutral mass spectrometry (SNMS) have been used to characterize
Sputter-induced cross-contamination in analytical AES and XPS instrumentation: utilization of the effect for the in situ deposition of ultrathin functional layers
Cross-contamination is observed on sample surfaces by Auger electron spectroscopy and X-ray photoelectron spectroscopy if multiple samples are mounted on one sample holder and a neighbouring sample
