All PVA TePla SAM systems are controlled by an advanced, intuitive graphical user interface and the WINSAM 8 control program running on a Windows® 10 platform. WINSAM 8 is easy to learn and can be used for numerous tasks.
The program makes it possible to save and recall the device setup parameters with every image saved in TIFF format. All SAM parameters can be called up and reset, which allows the system to perform multiple analyses under identical conditions.
- Adjustable amplification, gate width and gate delay before and during the scanning procedure
- Selectable threshold value, positive-negative peak-phase detection: amplitude, bipolar
- Completely flexible scanning field dimensions adjustable in the X and Y directions
- Flexible image resolution using selectable pixel size, configuration in the software
- Minimum pixel size 0.5 µm • Maximum resolution (32,000 x 32,000 pixels)
- Quick mode: Scanning with interpolation in the Y direction, e.g. with 500 x 250 resolution, can be applied to meander scan
- TIFF file contains multiple gate images
- SSP image display
- Flexible A-scan structure
- Visualization of the scanning field

For specific customers and samples, PVA TePla can develop image-processing software that is tailored to the needs of our customers. It can be used to process images of wafers with and without chip structures.
Image processing for wafers with chip structures
- Analyses using script language for specific chip structures
- Output of defects using wafer mapping (customer-specific formats are also possible)
Image processing for waters without chip structures
- Controlling the software using notch training
- Detection of defect size and position
- Inspection of the wafer edge
Our specific SECS/GEM interfaces provide the link between our systems and the connected production control system. They also enable the transfer of all production and system data, process values, and parameters.
This interface implementation meets the requirements of the SEMI Equipment Communications Standard (SECS) issued by the Semiconductor Equipment and Materials International (SEMI) industry association.
PVA TePla Analytical Systems GmbH has implemented SECS I, HSMS and Standard SECS II “Streams” and “Functions” for serial and TCP/IP communication with a host computer.
SAMnalysis combines state of the art pre- and post-processing algorithms with convenient results handling and a dedicated management system.
The software package was developed for the advanced failure analysis of SAM data, for quality control, and for scientific applications—for instance, in the areas of materials analysis, for biomedical problems, and for failure analyses in the semiconductor industry. Quantitative and qualitative evaluation routines and algorithms help to analyze recorded Z-scans.
