    摘要: A method is disclosed of controlling a LED, comprising driving the LED with a DC current for a first time, interrupting the DC current for a second time such that the first time and the second time sum to a period, determining at least one characteristic of the LED while the DC current is interrupted, and controlling the DC current during a subsequent period in dependence on the at least one characteristic. The invention thus benefits from the simplicity of DC operation. By operating at the LED in a DC mode, rather than say in a PWM mode, the requirement to be able to adjust the duty cycle is avoided. By including interruptions to the DC current, it is possible to utilize the LED itself to act as a sensor in order to determine a characteristic of the LED. The need for additional sensors is thereby avoided.

    摘要: Manufacturing a damascene structure involves: forming a sacrificial layer (20) on a substrate (10) to protect an area around a recess (30) for the damascene structure, forming a barrier layer (40) in the recess, and in electrical contact with the sacrificial layer, forming the damascene structure (50) in the recess, and planarizing. During the planarizing the sacrificial layer reacts electrochemically with the barrier layer or with the damascene structure. This can alter a relative rate of removal of the damascene structure and the sacrificial layer so as to reduce dishing or protrusion of the damascene structure, and reduce copper residues, and reduce barrier corrosion. The barrier layer can be formed by ALCVD. The barrier material being one or more of WCN and TaN. The sacrificial layer can be TaN, TiN or W.
