Offer Description

The electrical characterization of integrated passive devices produced in Caen by Murata IPS1 (Integrated Passive Solutions) is one of the research topics of the joint laboratory IPDN: Integrated Passive Devices of Normandy. This research laboratory associates Murata IPS and 3 CNRS mixed research units including GREYC2 (Caen Research Group in Computer Science, Image, Automation and Instrumentation).

The changes in the main characteristics of capacitors as a function of temperature, frequency and operating voltage depend mainly on the dielectric material and the manufacturing technology. Therefore, electrical characterization provides information on the quality of the dielectric and its operating range. The objective is to improve the manufacturing processes of very high performance integrated capacitors to adapt the next generations to emerging technical challenges (such as 5G technology).

A methodology for characterizing dielectrics has to be developed and confirmed by comparing our measurements with the properties of a widely studied dielectric. Planar capacitors with known dielectric will enable to validate this methodology and to compare the results of the various types of characterization. It will be interesting and innovative to link the RF performance to the dielectric quality deduced from DC or low frequency electrical transport measurements such as C(V), I(V) or DLTS (Deep Level Transient Spectroscopy).

Once this validation is done, this approach will be transposed to the dielectrics developed within the IPDN.

The objective of this PhD is to characterize the new dielectric materials developed by IPDN3 and the innovative architectures of the capacitors manufactured by the Caen site of the Murata group. The following points will be addressed:

State-of-the art study of dielectric characterization techniques

Design of an I-V and C-V characterization bench

Control of the measuring instruments via Python

Analysis of the electrical measurements

Electrical modeling of innovative capacitor architectures
