Exemplary embodiments provide integrated thin provisioning pool for primary logical volume and secondary logical volume in a storage subsystem. A mask layer with a predetermined pattern is formed on the GaN substrate to expose a partial area of the GaN substrate. A cantilever assembly includes a substrate support for supporting a substrate within the chamber. The image data of the pixel of interest of the input image is distributed to the interest pixel and a pixel adjacent to the interest pixel based on the coefficients.
