Patent ID: 8101925

Claim:
Nanofabrication installation comprising: a sample holder arranged for receiving a sample having a surface, at least one source arranged for emitting a beam of electrically charged particles in the direction of the sample holder in order to form the sample, a sample forming mask comprising a lower face oriented towards the sample holder, an upper face opposite to the lower face and arranged for receiving said particle beam emitted by said source in the direction of the sample holder to form the sample, and at least one through-opening between the upper and lower faces, arranged to allow a portion of said particles to pass through it in the direction of the sample holder, a beam shaping device arranged between said source and said mask, said shaping device being arranged for applying at least one of the following arrangements: concentration of the particles emitted by the source into clusters, filtering of the clusters having at least one desired characteristic selected from electric charge, mass, and the ratio of electric charge to mass, deflection of the clusters in the direction of the mask, a device for near-field detection arranged for detecting a desired relative position of said mask and said sample; a displacement device arranged for generating a relative movement of said mask and said sample holder in order to position the mask and the sample in said desired relative position, independently of the relative position of the source and the mask characterized in that the mask comprises at least one first electrode at the level of the through-opening arranged in order to electrically interact with the electrically charged particles passing through the opening.
