Various embodiments process semiconductor devices. In one embodiment, a release layer is applied to a handler. The at least one singulated semiconductor device is bonded to the handler. The at least one singulated semiconductor device is packaged while it is bonded to the handler. The release layer is ablated by irradiating the release layer through the handler with a laser. The at least one singulated semiconductor device is removed from the transparent handler after the release layer has been ablated.
