摘要：
The commercialization of gallium-nitride microwave circuits on diamond substrates requires chip-dicing technology and via formation process compatible with standard semiconductor processes. This paper discusses issues related to dicing and drilling of GaN-on-diamond wafers for RF power transistor applications (die size < 1 mm(2)) using laser micromachining. (C) 2011 Elsevier B.V.
