摘要:
The present invention provides a processing method which comprises the steps of subjecting the surface of a semiconductor substrate (701) or the surface of a substrate formed of a semiconductor, a metal or an insulator, to selective irradiation with a synchrotron orbit radiation (708a) so that electron donative properties of the surface are changed to give the desired pattern; and selectively depositing a metal film on the surface endowed with said electron donative properties. Furthermore, the present invention provides an apparatus for carrying out all the steps of fabricating a semiconductor device in a series of vacuum vessels capable of being evacuated, which comprises a load lock chamber (702); a film forming chamber; an etching chamber; a latent image forming chamber (707); a metal-film depositing chamber (713); a cleaning chamber; and a vacuum gate valve.

摘要:
A processing method comprises: a first step of depositing on a substrate which is a specimen a film of any one of a semiconductor, a metal and an insulator; a second step of subjecting the surface of the film deposited in the first step, to irradiation with a beam having a given energy to produce a physical damage on the surface; a third step of subjecting the film surface on which the physical damage is produced in the second step, to selective irradiation with light to partially cause a photochemical reaction so that a mask pattern depending on the desired device structure is formed on the film surface; and a fourth step of carrying out photoetching using as a shielding member the mask pattern formed in the third step.
