Embodiments of the invention include a selective deposition method that allows for coating of selective portions of an object, such as an electronic device, and inhibits coating of other selective portions of the object, such as the electric contacts. The selective deposition method includes providing a web to transport the object through a deposition chamber. The web may include and reference mechanisms to register the object relative to the web. The method further includes providing deposition material and a shadow mask that has open spaces in it to inhibit coating selective portions of the object. The deposition material serves as the coating material.
摘要:
Processes for simultaneously encapsulating multiple optoelectronic devices and/or depositing a barrier film onto multiple substrates suitable for fabrication of optoelectronic devices thereon include the use of a plasma deposition apparatus having multiple pairs of opposing electrodes for deposition of reactants onto the substrate that is used to form the device or the complete device itself. The processes significantly reduce tact time relative to one at a time batch processing that is currently used for manufacturing optoelectronic devices.
