摘要 / Abstract

End applications such as electric vehicles, wind energy and cellular base stations are also driving the demand for higher voltages and higher frequencies. SiC and GaN are the primary wide bandgap (WBG) semiconductors in use to address these challenging requirements. Last year Yole forecast that the SiC and GaN power device markets will reach $6B[1] and $2B[2], respectively, by 2027, exhibiting a CAGR of >30%, and more recently announced they expect the GaN RF market to exceed $2B by 2028[3]. Critical to the fabrication of these devices are the plasma etching steps, and uniform deposition of high quality dielectric and metal films. This paper will review specific etch and deposition needs and show examples of high productivity solutions. These will include hard-mask open, SiC/GaN etching, frontside and backside metallization and PECVD of low damage, stress-controlled SiN.
