摘要:
A method for manufacturing on a composite glass substrate a multi-colored LED for use in a video display board includes preparing a first masking layer on a composite glass substrate; depositing a first-color epitaxial layer on the first-color LED growing region and the first masking layer, to form a first-color LED; removing the first masking layer and the first-color epitaxial layer on the first masking layer; preparing a second masking layer, wherein the second masking layer is used to mask another region except a second-color LED growing region; depositing a second-color epitaxial layer on the second-color LED growing region and the second masking layer, to form a second-color LED; removing the second masking layer and the second-color epitaxial layer on the second masking layer; and grinding, cleaning, and performing an electrical test on a surface of the composite glass substrate.

A system is configured to provide a suite of network-based services to users with high availability. The suite of network-based services may include browser-based collaboration functions, process management functions, index functions, search functions, help search functions, document-management functions, and/or other functions. The suite of network-based services may correspond to services provided by a server application such as Microsoft® SharePoint™ being executed on one or more processors of one or more servers. As used herein, the term “high availability” may refer a system design protocol that ensures a certain degree of operational continuity during a given measurement period.
摘要:
In a method for depositing a barrier coating, a device is provided comprising a first portion and a second portion where a surface of the second portion is in a shadow zone. The device is pretreated wherein the pretreating alters a deposition rate of the barrier coating on a surface exposed to the pretreating. The shadow zone is substantially unexposed to the pretreating. A barrier coating is deposited wherein the barrier coating substantially conforms to a profile of the device. The coating may be a graded-composition barrier coating wherein a composition of the coating varies substantially continuously across a thickness thereof. The first portion may include a flexible, substantially transparent substrate. The second portion may include an electronic device. The barrier coating and first portion may encapsulate the second portion. The method is a single, commercially advantageous, barrier deposition process, enabling increased product throughput and low process tact time.
