PVA Tepla

PVA TePla Analytical Systems designs and manufactures state of the art Scanning Acoustic Microscopes. The company is owned by PVA TePla AG, a leading supplier of crystal growing systems for the semiconductor industry and photovoltaic applications. Technological developments have focused on the detection of structural defects and materials characterization within opaque materials. Scanning Acoustic Microscope (SAM) utilizes ultrasound to non-destructively examine surfaces and internal structures of a solid sample.  Voids, inculsions, cracks and even density variations are alle defects sensitive to the technique of acoustic microscopy. During the last 10 years our company introduced fully automated inline inspection SAMs for Si quality control, bonding inspection of MEMS, wafers and 3D integration products. PVA TePla operates an international sales and service network with own application laboratories in the US, Japan, Singapore and Malaysia. We cooperate with a large number of university facilities, such as Frauenhofer Institut and IMEC. Analytical Systems GmbH participates in a large number of funding projects and takes an active part in research and development in respect of ultrasound methodology and transducer development.
