An apparatus for manufacturing a display apparatus includes a deposition source, a nozzle head, a substrate fixer, and a deposition preventer. The deposition source is outside the chamber and vaporizes or sublimates a deposition material. The nozzle head is in the chamber, is connected to the at least one deposition source, and simultaneously sprays the deposition material onto an entire surface of a display substrate. The substrate fixer is connected to the chamber and moves linearly, with the display apparatus is mounted on the substrate fixer. The deposition preventer is in the chamber surrounding an edge portion of the nozzle head and an edge portion of the substrate fixer. The deposition preventer is heated during a deposition process.

Apparatus and method of manufacturing display apparatus

An apparatus for manufacturing a display apparatus includes: a chamber; a plurality of source units outside the chamber, wherein the plurality of source units which accommodate a deposition material and transform the deposition material into gas; a nozzle unit in the chamber, wherein the nozzle unit is connected to the plurality of source units and injects, into the chamber, the deposition material supplied from one of the plurality of source units; and a regulating unit between each of the plurality of source units and the nozzle unit, wherein the regulating unit interrupts the deposition material supplied from each of the plurality of source units to the nozzle unit and selectively connects the plurality of source units with the nozzle unit.

A method and apparatus for fabricating a vertical deposition mask capable of welding a mask sheet and a mask frame for preventing a large area mask from drooping due to the weight of the mask. The apparatus includes a tensioning device for tensioning a mask sheet and a welder for attaching a mask frame to a circumference of the mask sheet. The tensioning device includes clamps for supporting the mask sheet and tensioners coupled to the clamps for applying tensile force to the clamps and to evenly fix in place the mask sheet by the clamps.

A critical dimension controlling method in a semiconductor production process includes determining whether a model is to undergo a discontinuous production process when a run is inserted in a semiconductor manufacturing line, applying an offset for said model or a common offset for a model group including said model according to the determination, executing a production process in dependence upon a process variation along with the offset for the model or the common offset for the model group, and measuring an actual critical dimension in the production process. The offset for the model is calculated based on a previously measured actual critical dimension, and the calculated offset for the model is applied to the calculation of the common offset for the model group.
