Title
(EN) MULTI-STAGE CURING OF LOW K NANO-POROUS FILMS
(FR) TRAITEMENT A ETAPES MULTIPLES DE FILMS NANO-POREUX A FAIBLE CONSTANTE DIELECTRIQUE
Abstract
(EN)
Embodiments in accordance with the present invention relate to multi-stage curing processes for chemical vapor deposited low K materials. In certain embodiments, a combination of electron beam irradiation and thermal exposure steps may be employed to control selective outgassing of porogens incorporated into the film, resulting in the formation of nanopores. In accordance with one specific embodiment, a low K layer resulting from reaction between a silicon-containing component and a non-silicon containing component featuring labile groups, may be cured by the initial application of thermal energy, followed by the application of radiation in the form of an electron beam.
(FR)
Des modes de réalisation de l'invention concernent des procédés de traitement à étapes multiples pour des matériaux à faible constante diélectrique à dépôt chimique en phase vapeur. Dans certains modes de réalisation, une combinaison d'étapes de rayonnement à faisceau d'électrons et d'exposition thermique peut servir à contrôler le dégazage sélectif de porogènes incorporés dans le film, ce qui entraîne la formation de nanopores. Conformément à un mode de réalisation spécifique, une couche à faible constante diélectrique issue de la réaction entre un composé contenant du silicium et un composé ne contenant pas de silicium caractérisant des groupes labiles, peut être traitée par application initiale d'énergie thermique, suivie de l'application de rayons sous la forme d'un faisceau d'électrons.
