Integrated trench high density MIS (Metal Insulator Semiconductor) capacitors in Si-interposer are of great interest as they provide decoupling in a smart way using the third dimension of the silicon substrate. However, the use of various highly integrated passive components on the same Si-interposer is challenging regarding wide frequency band performances and signal integrity. Both aspects are addressed in this paper based on 300 kHz-20 GHz vector network analyzer measurements on 3D 80 nF/mm2 decoupling capacitors produced by IPDIA on a high resistivity substrate. Firstly, a scalable 1 MHz-10 GHz wideband model of a 3D capacitor in the 100 pF-10 nF range is developed. Secondly, 3D electromagnetic simulations of substrate and capacitive coupling between 3D capacitors using guard ring are presented. All simulations show good agreement with measurements. To the best of our knowledge, this is the first time that a wideband mathematical model as well as an RF crosstalk study have been published on embedded trench decoupling capacitors. © 2013 IEEE.

High-switching frequency dc-dc converters are present in many applications, where wide regulation bandwidth and high efficiency are needed. A three-MOSFET cascode bridge is presented to get full benefit from digital CMOS technology advancements. Three-dimensional assembly with a capacitive interposer is proposed for high-frequency efficient decoupling. A test-chip is designed in 40-nm CMOS technology, validating the operation and the efficiency performance of the converter using the proposed cascode bridge. A conversion peak efficiency of 91.5% is demonstrated when converting 3.3 to 2.4 V with a 150-mA load current, while switching at 100 MHz. © 1986-2012 IEEE.

The 3D Silicon technology of IPDiA is a disruptive capacitor and passive component technology for miniaturization adopted by the key players in the Medical domain for its very low leakage current, high stability and high reliability. It is also adopted by the Industrial market for its outstanding performance and reliability demonstrated in high temperature environment, up to 300°C. The high density Silicon capacitors with multiple metal-insulator-metal (MIM) layer stacks in 3D structures are reaching today 250nF/mm2 in mass production and have been demonstrating densities of up to 1μF/mm2, confirming the target of more than 4μF/mm2 in the coming years. In this paper, the robustness of the IPDiA technology will be exposed, illustrated by reliability results obtained through innovative platforms and packaging configurations used in various fields like implantable medical devices, automotive electronics and down hole drilling equipment. © 2014 CARTS International.
