Hi, I tried RF magnetron sputtering of AlN target. If you need to pattern the AlN film, you will need to play around with KOH wet etching. But KOH etches photoresist, so do take note of this.

Nitin, maybe reactive sputtering of Al with Argon and nitrogen to form ALN would work. Maybe worth a try. Gary Gary Hillman Service Support Specialties, Inc.
