    摘要: A method and apparatus for dispensing a liquid etchant onto a wafer dispenses the liquid etchant onto a wafer using a scanning dispensing nozzle while controlling the dispensing temperature of the etchant in real time as a function of the radial position of the dispensing nozzle over the wafer. The dispensing temperature of the etchant is controlled to enhance the effectiveness of the etchant and thus compensate for the lower etching rate zones in the wafer.

    摘要: A single wafer etching apparatus and various methods implemented in the single wafer etching apparatus are disclosed. In an example, etching a silicon nitride layer in a single wafer etching apparatus includes: heating a phosphoric acid to a first temperature; heating a sulfuric acid to a second temperature; mixing the heated phosphoric acid and the heated sulfuric acid; heating the phosphoric acid/sulfuric acid mixture to a third temperature; and etching the silicon nitride layer with the heated phosphoric acid/sulfuric acid mixture.

    摘要: A method of fabricating a semiconductor IC is disclosed. The method includes receiving a device. The device includes a semiconductor substrate, a plurality of fins and trenches between fins in the semiconductor substrate. The method also includes filling the trenches with a dielectric material to form shallow trench isolations (STI), applying a low-thermal-budget annealing to the dielectric material, and applying a wet-treatment to the dielectric material.
