Method for manufacturing semiconductor device including etching process of silicon nitride film

A manufacturing method of a semiconductor device includes the step for forming a silicon nitride film having a first part where arsenic is included and a second part where less amount of or substantially no arsenic is included, the step for removing at least a portion of the first part by dry etching, and the step for removing at least a portion of the second part by wet etching. Since arsenic in the silicon nitride film is removed by dry etching, arsenic is never eluted into the wet etching liquid from the silicon nitride film during subsequent wet etching. Therefore, one can prevent the wet etching from being contaminated. Etching of the silicon nitride film is performed by a combination of dry etching and wet etching. Therefore, compared with the case where etching is performed only by dry etching, plasma damage to the region exposed in the plasma atmosphere except for the silicon nitride film can be decreased.

Methods to mitigate plasma damage in organosilicate dielectrics

Methods of minimizing or eliminating plasma damage to low k and ultra low k organosilicate intermetal dielectric layers are provided. The reduction of the plasma damage is effected by interrupting the etch and strip process flow at a suitable point to add an inventive treatment which protects the intermetal dielectric layer from plasma damage during the plasma strip process. Reduction or elimination of a plasma damaged region in this manner also enables reduction of the line bias between a line pattern in a photoresist and a metal line formed therefrom, and changes in the line width of the line trench due to a wet clean after the reactive ion etch employed for formation of the line trench and a via cavity. The reduced line bias has a beneficial effect on electrical yields of a metal interconnect structure.
