Experiments and Models of DNA Nano—Catenary Patterns Manipulated by Liquid Flow

Individual DNA molecules were first stretched by a centrifugal force and adsorbed on a modified mica surface.Then,a liquid flow was guided across the surface along a direction perpendicular to the aligned DNA strands.Some nano-catenary-like patterns of DNA molecules were formed,which were revealed by atomic force microscopy.A physical mechanism called the “s-suspension bridge” model has been presented,by which the features of the catenary-like patterns of DNA molecules can be understood quantitatively quite well.

Effect of N2 Plasma Annealing of Properties of Fluoring Doped Silicon Dioxide Films with Low Dielectric Constant for Ultra—Large—Scale Integrated Circuits

The influence of N2 plasma annealing on the properties of fluorine doped silicon oxide (SiOF) films is investigated.The stability of the Dielectric constant of SiOF film is remarkably improved by the N2 plasma annealing.After enduring a moisture absorption test for six hours in a chamber with 60% humidity at 50℃,the dielectric constant variation of the annealed SiOF films is only 1.5%,while the variation for those SiOF films without annealing is 15.5%.Fourier transform infrared spectroscopic results show that the absorption peaks of Si-OH and H-OH of SiOF films are reduced after the N2 plasma annealing because the annealing can wipe off some unstable Si-F2 bonds in SiOF films.These Unstable Si-F2 bonds are suitable to react with water,resulting in the degradation of SiOF film properties.Therefore,the N2 plasma annealing meliorates the properties of SiOF films with low dielectric constant.
