摘要 / Abstract

Rapid growth in the compound semiconductor market, particularly demand for SiC devices, is creating significant manufacturing capacity challenges around the globe. This demand is fueling innovations in the SiC device supply chain - from the creation of larger substrates through higher productivity device manufacturing equipment. In particular, the unique requirements for doping SiC substrates are driving the industry to adopt a new class of ion implantation systems designed to address key production bottlenecks while also covering a wide operating space. This paper details the doping production bottlenecks that are unique to various device structures, e.g. Planar and Trench MOSFETs and introduces a new class of implanters designed to deliver the highest productivity with the lowest cost of ownership.
