Abstract: A feature in a layer is provided. A photoresist layer is formed over the layer. The photoresist layer is patterned to form photoresist features with photoresist sidewalls, where the photoresist features have a first critical dimension. A fluorine-containing conformal layer is deposited over the sidewalls of the photoresist features to reduce the critical dimensions of the photoresist features. Fluorine is removed from the conformal layer, while the remaining conformal layer is left in place. Features are etched into the layer, wherein the layer features have a second critical dimension, which is less than the first critical dimension.

Abstract: A thin film transistor substrate and a fabricating method thereof for simplifying a process are disclosed. In a liquid crystal display device according to the present invention, a gate line is provided on a substrate. A data line crosses the gate line with having a gate insulating film therebetween to define a pixel area. A thin film transistor includes a gate electrode connected to the gate line, a source electrode connected to the data line, a drain electrode opposed to the source electrode and a semiconductor layer for defining a channel between the source electrode and the drain electrode. A pixel electrode is connected to the drain electrode and is provided at said pixel area. Herein, said data line, said source electrode and said drain electrode have a double-layer structure in which a source/drain metal pattern and a transparent conductive pattern are built. Said pixel electrode is formed by an extension of the transparent conductive pattern of the drain electrode.

Abstract: A method for forming etch features in an etch layer over a substrate is provided. An etch mask stack is formed over the etch layer. A first mask is formed over the etch mask stack. A sidewall layer is formed over the first mask, which reduces the widths of the spaces defined by the first mask. A first set of features is etched into the etch mask stack through the sidewall layer. The mask and sidewall layer are removed. An additional feature step is performed, comprising forming an additional mask over the etch mask stack, forming a sidewall layer over the additional mask, etching a second set of features at least partially into the etch mask stack. A plurality of features is etched into the etch layer through the first set of features and the second set of features in the etch mask stack.

Abstract: The present invention is a process for transfer of a pattern of material from a donor substrate to a receiver substrate by lamination. The pattern of the transferred material is defined by an aperture in a mask interposed between the donor and receiver during lamination. The technique is compatible with flexible polymer receiver substrates and is useful in fabricating thin film transistors for flexible displays.
