PVA TePla Analytical Systems GmbH has been a ground-breaking expert in the field of acoustic microscopy for more than 30 years. With a range of leading solutions to suit all industries and fields of technology, we enable our customers to perform reliable non-destructive materials testing—from the inspection of solar and semiconductor systems all the way to failure analyses for ingots used in the production of wafers and MEMS systems.
To bring you all the advantages of acoustic microscopy at an outstanding price-performance ratio, we focus on creating a solid foundation. Every scanning acoustic microscope is based on a common component platform, which you can adapt and expand to the respective required system configuration at any time for specific applications. The long service life of our multi-channel systems guarantees you the best possible return on your investment.
Strict quality controls, highly-qualified engineers, and sales partners worldwide enable us to continuously further develop our technologies and processes. The focus in this case is on the resolution quality of our microscopes. Specially developed thin-film technology is used to create transducers with the world’s widest frequency ranges—from 3 to 2,000 MHz. Long-standing working relationships with leading research institutes (IMEC, Leti, Fraunhofer-Gesellschaften) contribute significantly to our shared success.
Takeover of an Italian vessel manufacturer
In 2019, the PVA TePla Group took over the activities of a renowned and globally acknowledged Italian vessel. As a result, our subsidiaries will be able - in addition to our existing suppliers - to purchase vessels from own production for the manufucturing of vacuum and crystal growing systems.
In 2018, the PVA TePla Group strengthens its metrology division.
PVA SPA Software Entwicklungs GmbH is a specialist for software and automation in the semiconductor industry as well as for optical metrology. This acquisition represents an important step forward for the further strategic development of the PVA TePla Group.
In 2016, PVA TePla further strengthened its position in the Chinese market by establishing a further sales and service location in the Xi'an high-tech region.
