Abstract:
1. A method of manufacturing a semiconductor integrated circuit device, comprising: (a) connecting an internal space of a sealed type wafer container, which accommodates a plurality of wafers, to a local clean chamber of a wafer treatment apparatus; (b) transporting a wafer accommodated in said wafer container under the connecting state to a load lock mechanism disposed between a wafer treatment chamber of said wafer treatment apparatus and said local clean chamber, through said local clean chamber, by a transport mechanism disposed in said local clean chamber, wherein a plasma treatment is performed in the wafer treatment chamber; (c) performing the plasma treatment to said wafer in said wafer treatment chamber, to provide a treated wafer, the treated wafer having a static charge; (d) after step (c), transporting the treated wafer in an unload lock mechanism disposed between the wafer treatment chamber of said wafer treatment apparatus and said local clean chamber, to said wafer container through said local clean chamber by said transport mechanism; (e) eliminating the static charge of said treated wafer during said step (d); and (f) releasing the connected state between said wafer container and said local clean chamber after said step (d), wherein a structure which effectuates said eliminating of the static charge of said treated wafer is disposed in said local clean chamber, said structure applying ionized gas to the treated wafer so as to eliminate the static charge.
