摘要:
A method for processing a sample using an electrically neutral reactive cluster is provided. The surface of a sample is processed by jetting out a mixed gas that is composed of a reactive gas and a gas with a boiling point lower than that of the reactive gas from a gas jetting part of a vacuum process room in which the sample is placed by a pressure in a range in which the mixed gas is not liquefied, in a predetermined direction, while adiabatically-expanding the mixed gas, thereby generating a reactive cluster and jetting the reactive cluster against the sample in the vacuum process room.

A substrate cleaning apparatus includes a supporting unit, provided in a processing chamber having a gas exhaust port, for supporting a substrate; one or more nozzle units, each for ejecting gas clusters to a peripheral portion of the substrate supported by the supporting unit to remove unnecessary substances from the peripheral portion; and a moving mechanism for changing relative positions of the supporting unit and the nozzle unit during ejecting the gas clusters. Each nozzle unit discharges a cleaning gas having a pressure higher than that in the processing chamber so that the cleaning gas is adiabatically expanded to form aggregates of atoms and/or molecules.

Disclosed is a technology in which a nozzle part is mounted in a vacuum chamber and a silicon substrate is held to face a discharge hole of the nozzle part. For example, ClF3 gas and Ar gas are supplied from the nozzle part and the mixed gas is discharged from the nozzle part under a vacuum atmosphere. By doing this, the mixed gas is adiabatically expanded and the Ar atoms or ClF3 molecules are combined, which become a gas cluster. The gas cluster is irradiated to the surface of the silicon substrate without being ionized and, as a result, the surface of the silicon surface becomes a porous state. Then, lithium is grown on the surface of the silicon substrate in a separate vacuum chamber 41 by sputtering without breaking the vacuum.

The plasma processing apparatus of the present invention increases the throughput of plasma processing. This objective is achieved by a composition which comprises a processing chamber (10) for performing surface processing of substrates (W) by means of a plasma discharge, load-lock chambers (20R) and (20L) whereto passage from the processing chamber (10) is possible through slots (11R) and (11L) formed in a wall portion (10a) of the processing chamber (10), a gate element (30) which opens and closes the slots (11R) and (11L) from within the processing chamber 10, and transport element(s) for transporting substrates (W) between the processing chamber (10) and the load-lock chambers (20R) and (20L).
