Abstract:

Various physical parameters of solvents within two component, PMMA + Solvent films are analyzed for their impact upon the coating uniformity of spin deposited PMMA films. Towards this end, a model is presented for describing the surface behavior of spin-on films during the latter stages of deposition, correlating the tendency of a film toward non-uniform deposition to physical characteristics of the spin-on solution. A finite difference solution to this model is presented for two-component, spin-on films that is shown to effectively predict the uniformity of the resulting thin-film layers.

This thesis details work on the utilization of dense phase carbon dioxide (CO2) in semiconductor processing. In particular, work is presented on the formulation of CO2 soluble photoresists and the spin coating of those photoresists using only liquid CO2 as a solvent. As part of this spin coating work, a novel high-pressure CO2 spin coater was designed and constructed, and the theoretical equations governing its performance were derived. Also discussed in this thesis are 248 and 193 nm exposures of these CO2 spun films and subsequent development in supercritical CO2. Resist stripping was also p

Compared with traditional diffusion of gases dopant (BBr3 or POCl3), SOD technique could lower the manufacturing cost and improve production efficiency. Furthermore, it is not toxic which can raise safety on production line. We first adjusted component ratio of dopant source, which can be spreaded on a small-sized substrate uniformly. Then we explore the rotation speed of spin coating to achieve

Abstract:

The process of applying a uniform thin film on a horizontal substrate is called spin coating. Spin coating relatively used in several industrial and scientific applications. In this study an attempted was made to numerically study the various factors affecting the spin coating process. CFD simulations were performed on 2D axisymetric geometry, VOF multiphase model was used to its work the liquid/gas interface, results from isothermal CFD simulation were first validated against theoretical values. Subsequently, CFD simulations were performed to determine the effects of flow important pa

Abstract:

Our reliance on semiconductors is on the rise with the ever growing use of electronics in our daily life. Organic-inorganic hybrid lead halide perovskites have emerged as a prime alternative to current standard and expensive semiconductors because of its use of abundant elements and the ease of solution processing. This thesis has shed light on the ink-to-solid conversion during the one-step solution process of hybrid perovskite formulations from DMF. We utilize a suite of in situ diagnostic probes including high speed optical microscopy, optical reflectance and absorbance, and grazing inci

This coating technique is quick and efficient. But, liquids such as photoresist are very expensive. During coating process, the maximum radius that can be coated is limited by a contact line instability, leading to the formation of rivulets or “fingers” at the leading edge. The onset of fingering instability makes the coating process inefficient and significantly affects wh
