Systems and methods for depositing materials on a substrate via OVJP are provided. A float table and grippers are used to move and position the substrate relative to one or more OVJP print bars to reduce the chance of damaging or compromising the substrate or prior depositions.

Organic vapor jet printing system

A method for testing a plurality of electronic devices formed on a large area substrate is described. In one embodiment, the method includes transferring a substrate on an end effector relative to a testing platform having a plurality of testing columns coupled thereto, the substrate having a plurality of electronic devices located thereon, and moving the substrate in a single directional axis relative to an optical axis of each of the plurality of testing columns, the single directional axis being substantially orthogonal to the optical axis to define a test area on the substrate, wherein the test area is configured to cover an entire length or an entire width of the substrate such that the testing columns are capable of testing the entire substrate as the substrate is moved through the test area.

In-line electron beam test system

An apparatus and method for testing large area substrates is described. The large area substrates include patterns of displays and contact points electrically coupled to the displays on the large area substrate. The apparatus includes a prober assembly that is movable relative to the large area substrate and/or the contact points, and may be configured to test various patterns of displays and contact points on various large area substrates. The prober assembly is also configured to test fractional sections of the large area substrate positioned on a testing table, and the prober assembly may be configured for different display and contact point patterns without removing the prober assembly from the testing table.

Prober for electronic device testing on large area substrates

A method and apparatus for testing a plurality of electronic devices formed on a large area substrate is described. In one embodiment, the apparatus performs a test on the substrate in one linear axis in at least one chamber that is slightly wider than a dimension of the substrate to be tested. Clean room space and process time is minimized due to the smaller dimensions and volume of the system.
