Software that extracts full performance from the multiband plasma process SMT driver The data acquisition software U9046 communicates with other software through a Microsoft COM interface. Intermediate software created for Microsoft COM interface and other interfaces (RS-232C, Ethernet, etc.) allows the U9046 to communicate with external units. This type of intermediate software for the U9046 is referred to as an SMT driver. The U9046 comes with an SMT driver sample program that was created with Visual Basic. Modifying this sample program allows the user to easily create an SMT driver that...

Option Software End point synthesis tool U8851 Overview Spectrum data acquired with a multiband plasma process monitor can be considered the sum of various spectral components including gas spectra and reaction product spectra. The U8851 analyzes the spectral components at each time and then extracts the spectral components which are newly generated at the endpoints. Endpoints are detected based on time-course changes in these spectral components. This makes it possible to detect an endpoint while making effective use of a wide spectral range. This is highly accurate detection compared to...

Highly accurate endpoint detection in plasma etching Analysis examples Optimizing the CVD cleaning (CF4, O2) after depositing SiN (SiH4, NH3, N2, Ar) film. The U8851 includes a library of typical material emission wavelengths that allows analyzing what materials have produced the acquired spectral components. In this example, N2, O and F line spectra appear on spectral components generated at the cleaning endpoint. The N2 spectral intensity can here be observed to decrease at the endpoint while the O and F spectral intensities increase. This analysis can be simultaneously performed on two...

Option Software Analysis and fault detection tool U9275 Overview As mentioned in the U8851 description, spectrum data acquired with a multiband plasma process monitor can be considered the sum of various spectral components including gas spectra and reaction product spectra. The U9275 finds statistical values such as mean and maximum relative to time-course changes in the spectral components being monitored, and assigns them key numbers. A normal range for each key number is also set. If a value exceeding that range is found, it is treated as a fault. By selecting a calculation method for...
