Web23 de fev. de 2024 · This is eliminated by immersion wet-etch, followed by a dielectric (ONO) and tungsten metal gate, deposition and finally etch-back. 1. Silicon nitride sacrificial removal and W etch-back have been identified as the two critical steps in this process flow. Each of these steps requires accurate real-time process control and metrology. Webetch rate. Silicon dioxide or silicon nitride is usually used as a masking material against HNA. As the reaction takes place, the material is removed laterally at a rate similar to the speed of etching downward. This lateral and downward etching process takes places even with isotropic dry etching which is described in the dry etch section.
