Abstract:
The present disclosure discloses a manufacturing method for a semiconductor apparatus, and relates to the field of semiconductor technologies. Forms of the method include: providing a semiconductor structure, where the semiconductor structure includes: a substrate and an interlayer dielectric layer on the substrate, where the interlayer dielectric layer has an opening for forming a gate; depositing a gate metal layer on the semiconductor structure to fill the opening, where the gate metal layer contains impurity; forming an impurity adsorption layer on the gate metal layer; performing a first annealing treatment on a semiconductor structure on which the impurity adsorption layer has been formed, to make the impurity in the gate metal layer enter the impurity adsorption layer; and removing the impurity adsorption layer after the first annealing treatment is performed. The present disclosure may reduce impurity in the gate metal layer, thereby improving contact resistance of the gate and improving device performance.

Claim (Index 15):
The method according to  claim 14 , further comprising:\n forming an insulator layer on the interlayer dielectric layer; patterning the insulator layer to form a source contact hole exposing the source, a drain contact hole exposing the drain, and a gate contact hole exposing the gate; forming a glue layer on side walls and the bottom of the source contact hole, the drain contact hole, and the gate contact hole; performing a second annealing treatment, so that parts of the glue layers on the bottom of the source contact hole and the drain contact hole are respectively combined with surface parts of the source and the drain to form silicide layers; and forming a source contact on the silicide layer of the source contact hole, forming a drain contact on the silicide layer of the drain contact hole, and forming a gate contact on the glue layer of the gate contact hole.
