Poly etch wet clean
WebJun 1, 2024 · Maskless etching approaches such as microdischarges and atmospheric pressure plasma jets (APPJs) have been studied recently. Nonetheless, a simple, long lifetime, and efficient maskless etching method is still a challenge. In this work, a separated type maskless etching system based on atmospheric pressure He/O2 plasma jet and … WebEDP etchant can be used on p-type wafers with <100> orientation, masked with either silicon dioxide or silicon nitride. It leaves a cleaner, smoother silicon surface with partial etch than KOH (see below). Heavy boron doping acts as an etch stop for EDP. Since EDP does not
