Title: Design for Manufacturability-A New Paradigm

Abstract: In today’s power electronics products, quality and reliability are given. Great emphases are placed on high efficiency, high power density and low cost. The current practice has reached a level of maturity that further advances will be closely linked to improvement in power devices, materials, and fabrication techniques.  
With recent advances in wide-band-gap (WBG) power semiconductor devices, namely, SiC and GaN, we have witnessed significant improvements in efficiency and power density while operating at a frequency an order of magnitude higher than the current practice using silicon counterparts. With this dramatic increased operating frequency, current design practices are challenged. Design trade off previously considered impractical or inconceivable can be realized not only with significant gain in efficiency and power density, but also drastic improvement of EMI/EMC and manufacturability. Several examples will be given to illustrate the potential impact of WBG devices in performance improvements and ease of manufacturability of future power electronics products.
