Thermal strain analysis considering in-plane anisotropy for sputtered AlN on c- and a-plane sapphire under high-temperature annealing

High-temperature annealing of sputtered AlN (Sp-AlN) using a face-to-face configuration is a novel technique that has attracted considerable attention because it can reduce the threading dislocation density of Sp-AlN to 107 cm−2. However, drawbacks such as cracking, residual stress, and wafer curvat...
