    摘要: A method for etching features in an etch layer. A conditioning for a patterned pseudo-hardmask of amorphous carbon or polysilicon disposed over the etch layer is provided, where the conditioning comprises providing a fluorine free deposition gas comprising a hydrocarbon gas, forming a plasma from the fluorine free deposition gas, providing a bias less than 500 volts, and forming a deposition on top of the patterned pseudo-hardmask. The etch layer is etched through the patterned pseudo-hardmask.

    摘要: A method for reducing line width roughness (LWR) of a feature in an etch layer below a patterned photoresist mask having mask features is provided. The method includes (a) non-etching plasma pre-etch treatment of the photoresist mask, and (b) etching of a feature in the etch layer through the pre-treated photoresist mask using an etching gas. The non-etching plasma pre-etch treatment includes (a1) providing a treatment gas containing H2 and COS, (a2) forming a plasma from the treatment gas, and (a3) stopping the treatment gas.
