    摘要: Embodiments of the present invention relate to a method for a near non-adaptive virtual metrology for wafer processing control. In accordance with an embodiment of the present invention, a method for processing control comprises diagnosing a chamber of a processing tool that processes a wafer to identify a key chamber parameter, and controlling the chamber based on the key chamber parameter if the key chamber parameter can be controlled, or compensating a prediction model by changing to a secondary prediction model if the key chamber parameter cannot be sufficiently controlled.

    摘要: A system and method for manufacturing an LED is provided. A preferred embodiment includes a substrate with a distributed Bragg reflector formed over the substrate. A photonic crystal layer is formed over the distributed Bragg reflector to collimate the light that impinges upon the distributed Bragg reflector, thereby increasing the efficiency of the distributed Bragg reflector. A first contact layer, an active layer, and a second contact layer are preferably either formed over the photonic crystal layer or alternatively attached to the photonic crystal layer.

    摘要: A light-emitting diode (LED) device is provided. The LED device has a lower LED layer and an upper LED layer with a light-emitting layer interposed therebetween. A current blocking layer is formed in the upper LED layer such that current passing between an electrode contacting the upper LED layer flows around the current blocking layer. When the current blocking layer is positioned between the electrode and the light-emitting layer, the light emitted by the light-emitting layer is not blocked by the electrode and the light efficiency is increased. The current blocking layer may be formed by converting a portion of the upper LED layer into a resistive region. In an embodiment, ions such as magnesium, carbon, or silicon are implanted into the upper LED layer to form the current blocking layer.
