Patent ID: 7097712

Claim:
An apparatus for processing a semiconductor comprising: a first vacuum chamber; an ion introducing apparatus for doping a semiconductor layer formed over a substrate with a dopant impurity through an insulating film comprising oxide provided over said semiconductor layer; an etching apparatus for etching said insulating film comprising oxide to expose a surface of said semiconductor layer, said etching apparatus connected to said ion introducing apparatus through said first vacuum chamber; a second vacuum chamber; a laser processing apparatus comprising a laser processing chamber and a laser for irradiating the exposed surface of said semiconductor layer with a laser light in said laser processing chamber after said etching, said laser processing chamber connected to said etching apparatus through said second vacuum chamber; and a mechanism for transporting said substrate from said ion introducing apparatus to said laser processing chamber without exposing said substrate to the air, said dopant impurity being made a plasma around a grid electrode of said ion introducing apparatus and being accelerated toward said semiconductor layer by a voltage applied to an anode electrode of said ion introducing apparatus.
