Abstract
A method of forming a direct contact lens on a light emitting device strure is disclosed which facilitates the formation of large arrays of light emitting devices. The method uses a printing fixture including a large number of vertically oriented pins which is dipped into a bath of a liquid epoxy material. The printing fixture is then placed over the array structures and lowered until the pins contact the diodes. When the printing fixture is subsequently raised, the lens material will adhere to the associated devices and flow to completely encapsulate the device and a substantial portion of the device mounting structure.
