US Power Electronics Technology and Manufacturing Roadmap

US Power Electronics Industry Collaborative (PEIC) has released US Power Electronics Technology and Manufacturing Roadmap. The report’s lead authors are Keith Evans, president of PEIC, and Dave Hurst, formerly a market analysis expert at NextEnergy.

“Recent advances in power semiconductor technology, particularly in wide bandgap materials, have opened up significant new opportunities for the U.S. power electronics industry, along with corresponding challenges,” said Keith Evans, PEIC president, in a statement. “The goal of PEIC’s participation in creating the report was to identify those technology and manufacturing challenges, and to present key strategic recommendations for the U.S. to develop effective solutions to meet the growing demands for efficient power electronics.”

While the need for innovation in semiconductors and passive components are two of the biggest challenges faced by the U.S. power electronics industry, the report also cites other roadblocks including a lack of strong power engineering talent, competition from overseas manufacturers, cost pressures, and a need for manufacturing innovation.

 

Trend Analysis

According to report, the recent advances in power semiconductor technology have opened up new opportunities for innovation in power electronics. Market and regulatory conditions have created global demand for power electronics systems that take advantage of new semiconductor technologies to enable higher-efficiency devices that operate at higher temperatures, higher frequencies, and higher voltages in smaller packages and lower overall system cost.

 

Wide bandgap (WBG) semiconductor devices

Development of wide bandgap (WBG) semiconductor devices is a major component of the global innovation race in power electronics. WBG semiconductor devices, especially SiC and GaN-on-Si devices, are beginning to penetrate the market, although Si devices continue to dominate the industry.

The U.S. WBG semiconductor device manufacturing supply chain is more developed in SiC device technology, while GaN-on-Si devices tend to be manufactured in Asian foundries, leveraging the massive silicon device foundry infrastructure there.

In addition, next-generation WBG semiconductors like bulk GaN and so-called ultra-wide bandgap (UWBG) semiconductors like gallium oxide (Ga2O3), aluminum gallium nitride (AlGaN) and diamond are in aggressive development as they promise additional performance advantages over SiC and GaN-on-Si.

“To meet these demands at scale, several technological and manufacturing challenges need to be overcome. This roadmap provides an overview of these challenges, the current state of the art, and emerging solutions to achieve these benefits. Emphasis is placed on understanding trends including inter-dependencies in semiconductors, capacitors, magnetics, and packaging technology. Using this information, this roadmap also presents key strategic recommendations for the U.S. to take advantage of these technological trends.”

Semiconductors are just one part of the overall power electronics system. While WBG and UWBG semiconductors are capable of operating at higher voltages and temperatures, today’s capacitors are not. Similarly, while WBG semiconductors are capable of operating at higher frequencies, today’s soft magnetics are not. Additionally, advances in packaging and thermal management are required before WBG semiconductors can be fully leveraged. The implication of improved semiconductor performance has ripple effects throughout the supply chain for power electronics.

 

Components

Components that support the overall power electronics systems, including capacitors, magnetic components, and packaging technologies are being pushed to match the new semiconductor performance levels, which in turn is creating market conundrums that are hampering growth of advanced semiconductors.

Current capacitor technologies struggle to match the high temperature performance needs, as existing capacitor technologies are limited by the properties of the dielectric used. Consequently, this presents a global innovation whitespace for the discovery and development of materials that exhibit the desired properties with reliability and durability that can meet a variety of applications.

Ferrites are the dominant form of soft magnetics used in power electronics systems today, primarily due to their low cost. However, they are bulky and reducing their size requires higher frequency operation, which causes high losses. Amorphous alloys and nanocrystalline materials are being explored as potential solutions to this issue, but none of the materials developed exhibit the desired performance characteristics at a competitive cost yet.

Power electronics market based on devices is classified into BJT, IGBT, MOSFET, power diode and thyristor. The IGBT devices dominate the industry and are likely to continue the trend over the forecast period. These devices are widely used across the industry due to the features such as enhanced efficiency, faster switching, minimal power loss and ease of usage at high voltages. In addition, increased requirement for power electronics devices is likely to offer several opportunities to the players operating in the power electronics market, according to report by Global Market Insights.

New packaging techniques and materials are being developed to improve the performance of power electronics systems at high temperatures with improved reliability over many thermal cycles. These innovations focus on two critical areas of packaging, the die attach and the interconnection. In order to ensure reliability at higher temperature, new die attach techniques and materials are under development, including Silver-Tin alloy soldering, silver sintering, and embedded packaging. Current interconnection methods are also prone to failure and lose reliability at higher temperatures. New interconnection techniques are under development, including ribbon bonding, ball bonding, and embedded packaging.
