Abstract

L'invention concerne une méthode pour protéger la surface d'un miroir situé dans un compartiment exposé à un rayonnement UV extrême (EUV). Ce rayonnement EUV est généré à partir d'un plasma qui émet à la fois un rayonnement EUV et des particules électriquement chargées. Des molécules organiques sont envoyées dans ce compartiment. Ces molécules organiques interagissent avec le rayonnement EUV pour former un revêtement de dépôts carbonés sur la surface du miroir. Les particules chargées émises à partir du plasma provoquent un choc sur les dépôts, ce qui provoque une érosion superficielle des dépôts situés sur la surface du miroir. En contrôlant au moins la vitesse de dépôt des dépôts sur la surface du miroir, et la vitesse de suppression des dépôts de la surface du miroir, l'épaisseur du revêtement peut être activement contrôlée à la fois pour empêcher les chocs directs des particules chargées sur la surface du miroir et pour minimiser la perte de réflectivité de la surface du miroir, en raison de la formation du revêtement. Cette méthode est également appropriée pour protéger la surface d'une fenêtre utilisée pour transmettre un rayonnement EUV à partir du compartiment.
