Patent CA-2445772-A1 (CA)
Inventor: SEIFERT WERNER
IPC: H01L21/20
Filed: 2002-04-30
Abstract: L'invention concerne un procédé de fabrication d'une grande couche de germanium sur un substrat de silicium. Ce procédé consiste à former une couche de germanium initiale sur le substrat de silicium de manière à obtenir des protubérances S-K arrondies par décalage de l'axe cristallographique. L'oxydation entraîne la formation de dioxyde de silicium entre lesdites protubérances. Une opération de réduction ultérieure expose le sommet des protubérances. Du fait qu'ils soient presque complètement relâchées et libres de toute tension, ces sommets forment des sites de nucléation destinés à la croissance d'une dernière couche de germanium, formée de monocristaux qui s'étendent depuis le site de nucléation.

Abstract: Cette invention concerne une source de désorption-ionisation par impact laser assistée par matrice (MALDI) (1) utilisée à la pression atmosphérique ou sous dépression en interface avec un guide d'ions multipôle (8) ou un cône de passage ionique sous application de formes d'onde en courant alternatif "CA ou RF". Les guides d'ions multipôles (8, 68) ou les cônes de passage ionique transportent, piègent et/ou séparent des ions produits par une source MALDI (1) et dirigent lesdits ions vers un analyseur de masse (3) pour analyse MS ou MS/MSn du rapport masse/charge. Les cibles échantillons MALDI (4) peuvent être disposées à l'entrée d'un guide d'ions multipôle (8) ou d'un cône de passage ionique, le flux gazeux (14) et les champs électriques étant conçus pour diriger efficacement les ions dans le guide d'ion (8) ou dans le cône de passage ionique. Les ions produits par MALDI (1) à la pression atmosphérique ou sous des dépressions intermédiaires entrent en collision avec un gaz neutre pendant leur transport dans le guide d'ions multipôle (8) ou dans le cône de passage ionique en présence de champs électriques RF. Les collisions avec le gaz servent à amortir les trajectoires des ions vers l'axe central des ions, ce qui améliore l'efficacité du transport dans à l'intérieur et au travers du vide. Le guide d'ions multipôle et le cône de passage ionique assurent la mobilité des ions et la séparation masse/charge de ces ions pendant leur transport et leur focalisation.
