A color filter substrate for a liquid crystal display device and a method of fabricating the same includes black matrixes on a transparent insulating substrate, the black matrixes defining pixel areas and having a first region and a second region, color filters in the pixel areas and having areas overlapping the first region of the black matrixes, and ball spacers above the second region of the black matrixes, wherein a thickness of the first region is greater than a thickness of the second region.

The present invention provides applicators reducing generating bubble. Dispersion liquid is supplied while the pressure of a circulation tank on the delivery side is lower than the atmospheric pressure but higher than the pressure of the space in buffer tanks. The dispersion liquid in the discharge chambers is recovered while the pressure in a circulation tank serving as recovery destination is lower than the atmospheric pressure. Gas dissolution can be reduced because the dispersion liquid does not come into contact with gases at pressures higher than the atmospheric pressure and engulffing gas or deformation of solid microparticles can be avoided because no pump is used.

According to the present disclosure, a printer apparatus may include a chuck configured to support a substrate thereon, a rail spaced apart from the chuck, a printhead carriage frame coupled to the rail, and a printhead carriage pivotally coupled to the printhead carriage frame.

Rotatable printhead array

The present teachings relate to a printhead maintenance station for an industrial printing apparatus which is used to prevent clogging of the printhead, particularly during periods in which the printheads are idle. The maintenance station includes a capping station which has sockets for keeping the printheads moist and a blotting station for cleaning any residual printing fluids prior to carrying out a print function.

A platen for use in chemical mechanical planarization (CMP) systems is disclosed. The platen is arranged below a linear polishing pad and designed to apply a controlled fluid flow to the underside of the linear polishing pad. The platen includes a leading zone containing a first plurality of output holes. The leading zone is oriented more proximate to an upstream region of the linear polishing pad. The platen also includes a trailing zone containing a second plurality of output holes. The trailing zone is oriented more proximate to a downstream region of the linear polishing pad. The leading zone and the trailing zone are independently controlled and designed to output the controlled fluid flow independently from each of the first plurality of output holes and the second plurality of output holes.
