Abstract

Qualification du nouveau diélectrique ESL 4917 & problèmes de compatibilité avec certains conducteurs – détermination d'une solution pratique par mélange entre les diélectriques ESL 4913 et ESL 4917. Le diélectrique standard ESL (ElectroScience Laboratories) 4913 offre une bonne compatibilité avec les couches épaisses, mais a le défaut de trop couler à la sérigraphie. Le nouveau diélectrique ESL 4917 est plus vitreux et semble plus dense, et a en plus l'avantage d'être aussi semi-transparent, ce qui permet une vérification des couches intérieures. Cependant, si ESL4917 est bien compatible avec les conducteurs riches en Ag, des délaminations spontanées sont apparues avec le conducteur Ag:Pd plus richement allié en Pd, ESL 9635G ; l'incompatibilité entre la fritte de verre de ce dernier et ESL 4917, plus vitreux, en est probablement la cause. Le mélange des deux diélectriques, en proportion ESL 4913:4917 1:1 ou 1:2, permet largement de résoudre ces problèmes : le résultat est raisonnablement dense, et on obtient apparemment une bonne compatibilité avec ESL 9635G, surtout si celui-ci est déposé sur une couche de fond riche en Ag.

Mise-en-scène (mi.z‿ɑ̃.sɛn; "placing on stage" or "what is put into the scene") is the stage design and arrangement of actors in scenes for a theatre or film production, both in the visual arts through storyboarding, visual theme, and cinematography and in narrative storytelling through direction. The term is also commonly used to refer to single scenes that are representative of a film. Mise-en-scène has been called film criticism's "grand undefined term.

Fermat's little theorem

Fermat's little theorem states that if p is a prime number, then for any integer a, the number is an integer multiple of p. In the notation of modular arithmetic, this is expressed as For example, if a = 2 and p = 7, then 27 = 128, and 128 − 2 = 126 = 7 × 18 is an integer multiple of 7. If a is not divisible by p, that is if a is coprime to p, Fermat's little theorem is equivalent to the statement that ap − 1 − 1 is an integer multiple of p, or in symbols: For example, if a = 2 and p = 7, then 26 = 64, and 64 − 1 = 63 = 7 × 9 is thus a multiple of 7.
