Apparatus for plasma jet treatment of substrates
First Claim
1. An apparatus for treating two pluralities of substrates with a plasma jet, the apparatus having a first carousel for holding a first plurality of substrates, and a second carousel for holding a second plurality of substrates, the apparatus further characterized in that each carousel has a rotatable angle drive (10, 210) having rotation axes Da1, Da2 ;
- a plurality of arms (20a-20c, 220a-220c) extending radially from the respective angle drives;
a plurality of rotatable substrate holders (40a-40c, 240a-240c), each of the substrate holders being connected to one of the arms, each of the rotatable substrate holders having a rotation axis Ha1i, Ha2i positioned at a distance R from the rotation axis Da1, Da2 of its respective angle drive;
a plasma jet generator (90) for providing a plasma jet (80) having a first cross-sectional axis P1 and a second cross-sectional axis P2 ; and
means (190) for moving the plasma jet generator from a first position Z1 adjacent to the first carousel to a second position Z2 adjacent to the second carousel.

Abstract
An apparatus for processing substrates with a plasma jet with increased throughput is described. The apparatus comprises at least two carrousels for holding a plurality of substrates. Each of the carrousels includes a rotatable angle drive having a rotation axis Da, a plurality of arms extending radially from the angle drive and a plurality of rotatable substrate holders. Each of the substrate holders is connected to one of the arms, each of the rotatable substrate holders has a rotation axis Ha positioned at a distance R from the rotation axis Da of the rotatable angle drive. The carousel angle drive provides programmable motion of the substrates being treated relative to a plasma jet generator. The plasma jet generator is movable from a first position Z1 adjacent to the first carousel to a second position Z2 adjacent to the second carousel. While the substrates on the first carousel are being treated by the plasma jet, the substrates on the second carousel can be loaded or unloaded. Once the treatment of the substrates on the first carousel is completed, the plasma jet is moved from the first position Z1 to the second position Z2 to treat the substrates on the second carousel and allow loading and unloading of substrates from the first carousel.
