In the manufacture of electronic devices arrayed on a substrate to form respective parts of a common product, the electronic devices each having a common structure comprising multiple layers, a method of forming a specific layer of the common structure using a printer having a print head, the print head having nozzles to eject a liquid onto the substrate in order to form the specific layer of each of the electronic devices, the method comprising:receiving information for each corresponding one of the nozzles which identifies expected volume of droplets to be produced by the corresponding one of the nozzles, the information representing empirical measurement of a droplet produced by the corresponding one of the nozzles, the information to identify picoliter-scale variation in the expected volume from nozzle-to-nozzle;
for each of the electronic devices, identifying an associated droplet combination for which the corresponding expected volumes necessarily sum to a value lying within a predetermined volume tolerance range;
for each of the electronic devices, controlling the printer so as to deposit the associated droplet combination of the liquid into a fluidic well for the one of the electronic devices; and
processing the liquid once in the fluidic well to form the specific layer for each of the electronic devices, wherein processing includes at least one of baking the liquid or curing the liquid;
wherein the printer is to move the print head in a scanning direction relative to the substrate during deposition of the droplets, and wherein for at least two of the electronic devices which are adjacent to one another in a dimension orthogonal to the scanning direction relative to others of the electronic devices, the associated droplet combinations differ from one another;
wherein the method further comprises intermittently performing a calibration operation,
wherein performing the calibration operation comprises
transporting the print head relative to a droplet measurement system, to bring the print head and the droplet measurement system into proximity of one another,
sequentially using a laser device to measure droplet volume for at least one droplet produced by each one of the nozzles of the print head and, dependent on the measured droplet volume, associating an expected droplet volume with the one of the nozzles, and
updating the information for each corresponding one of the nozzles which identifies expected volume of droplets to be produced by the corresponding one of the nozzles; and
wherein identifying the associated droplet combination for each one of the electronic devices is performed in dependence on the updated information obtained from the calibration operation.

ENVIRONMENTALLY CONTROLLED COATING SYSTEMS

Kateeva, Inc., Newark, C...

1. A method for providing a coating on a substrate, comprising:transferring the substrate to a slot die coating apparatus housed in an enclosure;
depositing an organic material in a pattern over a deposition region using the enclosed slot die coating apparatus, the deposition region being over at least a portion of an electronic device fabricated upon a substrate;
transferring the substrate with the organic material deposited thereon to an enclosed curing module;
supporting the substrate in the enclosed curing module using a pressurized gas cushion distributed between the substrate and a substrate support apparatus, the pressurized gas cushion being sufficient to float the substrate above the substrate support apparatus; and
performing an optical treatment on the organic material deposited on the substrate in the enclosed curing module to form an organic film layer in the pattern over the deposition region.

FABRICATION OF THIN-FILM ENCAPSULATION LAYER FOR LIGHT EMITTING DEVICE

Kateeva, Inc., Newark, C...

11. An apparatus for fabricating a thin film encapsulation layer for an electronic device having light emitting elements, the thin film encapsulation layer to have a desired thickness, the apparatus comprising:a gas enclosure to receive a substrate, the light emitting elements formed on the substrate;
an ink jet printer within the gas enclosure, the ink jet printer to print droplets of ah a liquid organic material onto the substrate, in a manner so as to form a liquid organic material coat over the light emitting elements;
circuitry configured to receive at least one value that represents a variable layer thickness and corresponds to the desired thickness, the circuitry configured to control a first volume of the liquid organic material printed per a first unit area of the substrate in dependence on the at least one value by causing the ink jet printer to vary at least one of a droplet area density or a size of the droplets, wherein a thicker liquid organic material coat is formed by a greater droplet area density or size and a thinner liquid organic material coat is formed by a lesser droplet area density or size, wherein the circuitry specifies, based on the at least one value, the thickness of the liquid organic material coat; and
a processing mechanism to process the liquid organic material coat once deposited to form the thin film encapsulation layer from the liquid organic material coat so as to have the desired thickness.
