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： A damascene process is described using a copper fill process to fill a trench (12). The copper fill (20) is started with a deposited seed layer which includes (5) copper and titanium. Some titanium migrates to the surface during the copper fill process. The structure is annealed in a nitrogen atmosphere which creates a self-aligned TiN barrier (24) at the surface of the copper fill (20). Air gaps (26) may be created in the same annealing process. The process may be used to form a multilayer structure.

摘要： A method of manufacturing a semiconductor device with precision patterning is disclosed. A structure of a small dimension is created in a material, such as a semiconductor material, using a first and a second pattern, the patterns being identical but displaced over a distance with respect to each other. Two mask layers are used, wherein the first pattern is etched into the upper mask layer with a selective etch, and the second pattern is created on the upper mask layer or on the lower mask layer at locations where the upper mask layer has been removed. A part of the lower mask layer and/or the upper mask layer is etched according to the second pattern, resulting in a mask formed by remaining parts of the lower and upper mask layers, the mask having a structure with a dimension determined by a displacement of the second pattern with respect to the first pattern.

摘要： Apparatus for regulating the temperature of a light emitting diode (LED). The apparatus includes a heat sink, an LED mount, and an LED mounted on the LED mount. The LED mount is configured to change shape in response to a change in temperature. The change in shape alters the position of the LED relative to the heat sink, for adjusting heat transfer between the LED and the heat sink. The LED mount may include a laminated portion such as a bi-metallic strip.
