Thermal Management of Chip-Scale GaN Devices

Thermal Management of Chip-Scale GaN Devices

This article discusses the challenges that thermal management raises due to increase power density, especially with chip-scale packaging (CSP). What is sometimes overlooked, however, is that CSP eGaN® power FETs and integrated circuits have excellent thermal performance when mounted on standard printed circuit board (PCBs) with simple methods for attaching heat sinks. Simulations, supported by experimental verification, examine the effect of various parameters and heat flow paths to provide guidance on designing for performance versus cost.

Testing Gallium Nitride Devices to Failure Under Extreme Voltage and Current Stress

Testing Gallium Nitride Devices to Failure Under Extreme Voltage and Current Stress

Standard qualification testing for semiconductors typically involves stressing devices at-or-near the limits specified in their data sheets for a prolonged period of time, or for a certain number of cycles, with the goal of demonstrating zero failures. By testing parts to the point of failure, an understanding of the amount of margin beyond the data sheet limits can be developed, but more importantly, an understanding of the intrinsic failure mechanisms of the semiconductor can be found.

矽片已死……離散功率元件快將消失

矽片已死……離散功率元件快將消失

在超過四十年中,隨著功率MOSFET元件的結構、技術和電路拓撲的創新,可滿足不斷增長的電力需求,因此改善了電源管理的效率和成本。 然而,在這新世紀的發展,隨著矽功率MOSFET元件已經接近其理論極限,其改進速度已大為減慢。 與此同時,一種全新材料 - 氮化鎵(GaN)- 正朝著新的理論性能領域的方向,穩步發展,其性能是老化的MOSFET元件的6,000倍,以及是目前市場的最優越GaN元件的300倍。

GaN Integrated Power Stage – Redefining Power Conversion

GaN Integrated Power Stage –  Redefining Power Conversion

Beyond just performance and cost improvement, the most significant opportunity for GaN technology to impact the power conversion market comes from its intrinsic ability to integrate multiple devices on the same substrate. GaN technology, as opposed to standard silicon IC technology, allows designers to implement monolithic power systems on a single chip in a more straightforward and cost-effective way.
