The order of the reactants affected the Si etch rate. Changing the exposure sequence from O 2−HF−TMA to O 2 Decreasing the etch temperature below 290 °C also resulted in a decrease in the Si etch rate. Atomic ...

WebNova Science Publishers WebThe contact opening step typically comprises an isotropic etch is typically followed by an anisotropic etch. When the design rules are very tight, the isotropic contact etch step has to be minimized to avoid exposing underlying structures that can then be shorted to the metal when it is deposited in the contact hole. WebFeb 1, 2011 · To achieve the desired and predictable wet etch rate of BPSG in a buffered oxide etch (BOE), calculated control limits were placed on the boron and phosphorus … gregory themes
