Online-Session: Advanced Packaging: »Dielectric Characterization of Materials«
Fraunhofer IZM specializes in applied and industrial contract research. With technology clusters in the field of wafer and substrate process technology as well as a high level of competence in simulation and measurement technology, the entire spectrum required for the implementation of reliable electronics and their integration into the application is covered.
Within the online expert session series "Advanced Packaging: Simulation, Technology, and Reliability" we would like to introduce Fraunhofer IZM and thematize specific technological topics. Especially, we want to show which of our latest research results and approaches you can use for your own applications/developments or as basis for joint projects.
What to expect from our Online-Sessions:
In our 45-minutes expert sessions we would like to present to you trending topics in a technical presentation. Afterwards, our experts will be available for your questions and comments and a joint discussion.
New topics and dates for this workshop series will be published regularly on this webpage.
Participation is free of charge, registration is required. This workshop series aims to address our customers, partners and interested parties from industry, politics and science.
This Session's Topic: Dielectric characterization of Materials and their impact on Interconnects for High Frequency Applications & Package Design
The characterization of electrical properties of materials (permittivity & loss factor) plays a key role in the design of entire RF packages and their corresponding interconnects in the entire system. While the determination of these parameters in the range below 1 GHz is still relatively easy using capacitive probes, the extraction of these parameters for the range 5G and higher poses a particular challenge. In this range, the electric field is no longer decoupled from the magnetic field due to the frequency and thus an electromagnetic wave is present, so other methods are required. One is e.g. a cavity resonator for the frequency range of 10 GHz - 26 GHz or a quasi-optical bank for the characterization of the range of 40 GHz - 170 GHz. In addition to the extraction process of the parameters, the materials change their electrical properties over time due to environmental influences such as temperature and humidity, which can lead to entire system failure. It is therefore necessary to know these effects from the beginning of the package design.
