To achieve the tight degree of within-chip etch control needed for such precise patterning, the new system creates a dramatically cleaner chamber environment that significantly accelerates the removal of etch byproducts—a major cause of variation. Both larger chamber volume and higher gas flows minimize the amount of byproduct that redeposits on the wafer, where it can pinch off narrow spaces and create etch depth variations, cause unacceptable variations between densely packed and isolated features, or exacerbate line edge roughness. Preventing byproduct accumulation also reduces particle formation and resultant defect creation.
La dimension très spéculative du marché immobilier peut avoir une influence sur les prix voire être en partie à l'origine d'une crise mondiale comme la crise de 2007, lorsqu'elle aboutit à la constitution d'une bulle immobilière, dont l'importance peut être aussi grande que celle des bulles financières et dans certains cas se conjuguer avec une bulle financière ou dans d'autre cas être cause d'un krach financier international.

A broker provides a complete and accurate description of the property, performs a comparative market analysis, proposes a marketing strategy, verifies the specifications of the desired property, prepares and submits the promise to purchase to the seller, negotiates in the best interest of his or her client, and ensures that all conditions are met on time for the signing of the notarial act.
