Abstract:

When azobenzene-modified photosensitive polymer films are irradiated with light interference patterns, topographic variations in the film develop that follow the electric field vector distribution resulting in the formation of surface relief grating (SRG). The exact correspondence of the electric field vector orientation in interference pattern in relation to the presence of local topographic minima or maxima of SRG is in general difficult to determine. In my thesis, we have established a systematic procedure to accomplish the correlation between different interference patterns and the topogra

Abstract:

Ein neuentwickeltes azobenzenhaltiges Material, das auf einem supramolekularen Konzept basiert, wird bezüglich seiner Strukturbildung während einer holografischen Belichtung bei 488 nm untersucht. Im Mittelpunkt stehen dabei eindimensionale, sinusförmige Reliefs mit Periodizitäten kleiner 500 nm. Es wird gezeigt, wie der Grad der Vernetzung der photosensitiven Schicht die Strukturbildung in diesem Größenbereich beeinflusst. Zur Maximierung der Strukturtiefe werden gezielt Prozessparameter der Belichtung sowie Materialparameter variiert. Unter Standardbedingungen und moderaten Belichtungsintens

Abstract:

Ce manuscrit de thèse porte sur la formation de masques de réseaux denses de nanopiliers ou nanotrous à partir de l'auto-assemblage de copolymères à blocs (CPB) à haute force de ségrégation, pour des applications dans la micro-électronique. Des copolymères à blocs, de type ABA, constitués d'un bloc central de polydiméthylsiloxane (PDMS) et de deux blocs terminaux de polylactide (PLA) ont été synthétisés par polymérisation par ouverture de cycle. Les caractérisations de deux CPB d'intérêt en masse et sous forme de film mince montrent une mesostructure hexagonale sphérique et cylindrique de PLA

Such a scattering problem has been formulated as a rigorous boundary value problem under the most general incidence condition. In addition, the diffra- ction efficiency of grating is investigated for different par- ameters of the grating as well as the incident wave. Particul- ar attention is focused

First, a Bragg grating mold was formed on a glass substrate using the holographic interference lithography and photolithography, and after that the polymer grating structure was transferred to the surface of a D-shaped optical fiber by using the soft lithography technology. This experimental measurement was performed by a tunable laser. The reflectio

Metrology measure and control critical dimension (CD) uniformity, overlay, thickness of each layer, defect after exposure or through some chemical process. Optical metrology is one of the non-contact, rapid and non-destructive method and preferable method in semiconductor manufacturing process.

Firstly, we adopt a numerically stable mathematical calculation called rigorous coupled-wave analysis, RCWA, to optimize the profile of grating structure. Then we realize it onto real InGaP/GaAs/Ge III-V MJ solar cell. Lastly, the efficiencies will be measured under standard AM1.5G solar spectrum at various incidences. In general, the experiment results of samples with grating present higher effi
