Half-tone proximity lithography
The half-tone lithography using pixilated chromium masks in a projection stepper is an established technology in microoptics fabrication. However, the projection lithography tool is comparably expensive and the achievable lateral resolution is typically limited. By using pixel diffraction effects, binary and continuous profile lithography with submicron resolution can be installed on a conventi...
متن کاملExcimer Laser Micromachining of Polymers using Half-tone Masks: Mask Design and Process Optimization
Laser micromachining by projection with half-tone masks is a useful technique for fabricating microstructures with stepped multi-level or continuous surface relief. However, design of the mask transmission function to achieve a particular surface profile is a non-trivial problem except when the surface relief is shallow compared to the focal depth of the projection optics. In this paper we desc...
متن کاملTone Recognition of Continuous Thai Speech Under Tonal Assimilation and Declination Effects Using Half-Tone Model
This paper presents a method for continuous Thai tone recognition. One of the main problems in tone recognition is that several interacting factors affect F0 realization of tones. In this paper, we focus on the tonal assimilation and declination effects. These effects are compensated by the tone information of neighboring syllables, the F0 downdrift and the context-dependent tone model. However...
متن کاملTrichromatic opponent color classification
Stimuli varying in intensity and chromaticity, presented on numerous backgrounds, were classified into red/green, blue/yellow and white/black opponent color categories. These measurements revealed the shapes of the boundaries that separate opponent colors in three-dimensional color space. Opponent color classification boundaries were generally not planar, but their shapes could be summarized by...
متن کاملThe Effect of Process Parameters on the Apparent Defects of Tape-Cast SOFC Half-Cell
Using flawless components are important for a proper material selection and best working conditions to achieve the best performance of solid oxide fuel cells (SOFCs). Tape casting is the most used process for the fabrication of SOFC parts, especially anode and electrolyte due to its advantages regarding the other processes. In this study, the effect of slurry composition and milling time were s...
