Silicon Capacitors with extremely high stability and reliability ideal for high temperature applications

Abstract

With the wide range of existing capacitors, the end user's requirements are roughly met but most of the capacitors see their performances largely impacted when they are submitted to high temperature. In this paper we present the Silicon Capacitors highly recommended for applications in the geothermal, oil well logging, automotive and military. They can operate in a wide operating temperature range and they withstand temperature up to 250°C, with extremely high insulation resistance and very good stability. These capacitors, already extensively used for years in miniaturized equipment and computers, feature high miniaturization with a large capacitance to volume ratio, thanks to the IPDiA 3D Silicon technology, extremely stable and reliable even at 100μm thickness. Available in hundreds or thousands of nanofarads, in various sizes and custom configurations, these capacitors are usable at low frequencies but they are also appropriate for RF applications. The recent progress in the 3D Silicon Capacitor IPDIA technology, which moves the world wide record from 250nF/mm2 up to 550nF/mm2, will give even more room to higher integration. This is an ultra key driver to growth for High reliability applications.

ATHENIS_3D: Automotive Tested High-voltage and Embedded Non-volatile Integrated SoC Platform with 3D Technology

“…By considering 50% of silicon surface patterned with 8 µm holes, the obtained integration density of 36 nF/mm 3 is higher than the typical value for the class 1 ceramic capacitors offering an integration density of 10 nF/mm 3 [12]. Although the integration density of commerically available low voltage 3D capacitors is up to 250 nF/mm 3 [13], these capacitors operate at only 6 V which is far below the operating voltage required in hybrid/ electric vehicles where 48 V DC bus [14,15] is used. 6 V is also below the requirement of current vehicle industry where 12 V (cars) or 24 V (trucks) are required.…”

Universal and inductorless DC/DC converter for multi-output power supplies in sensor and actuator networks

“…The use of 3D technology allows to stack the passive device on the silicon die reducing the PCB area and the assembly cost of the whole system. Today the integration density of commercially available low voltage 3D capacitors is up to 250 nF/mm 3 [6] but these capacitors operate at only 6 V. The operating voltage of the capacitors depends on the dielectric thickness. A higher width and a higher voltage lead to lower capacitance.…”

“…Toyota EV traction inverter with double-sided cooling of power modules [79] used in Prius models. [73] and glass [74] have been reported in the literature that can operate at temperatures greater than 250 °C and 200 °C, respectively. Inductor cores using powder as the core material are available that permit safe operation at temperatures up to 200 °C.…”
