Abstract: Methods for fabricating a semiconductor devices, and in particular light emitting diodes (LEDS) comprising providing a plurality of semiconductor devices on a substrate and forming a contact on at least some of the semiconductor devices. A containment structure is formed on at least some of the semiconductor devices having a contact with each containment structure defining a deposition area excluding the contact. A coating material is deposited then within the deposition area, with the coating material not covering the contact. A light emitting diode (LED) chip wafer comprising a plurality of LEDs on a substrate wafer with at least some of the LEDs having a contact. A plurality of containment structures are included, each of which is associated with a respective one of the plurality of LEDs. Each of the containment structures at least partially on its respective one of the LEDs and defining a deposition area on its respective one of the LEDs. The deposition area excludes the contact.
