    Abstract: A circuit can provide an approximately constant resistance value that is virtually independent of process and temperature variations. A current control circuit may use a device that tracks the changes in a corresponding device over process and temperature variations. As a result, the behavior of device may be used to help determine the control information provided to device in order to maintain an approximately constant resistance Rm over process and temperature variations. The approximately constant resistance Rm may be used to provide an approximately constant current ILED. A wide variety of applications, not just LED drivers, may benefit from the use of an approximately constant resistance and/or current.

    Abstract: A voltage source provides an output voltage to drive a plurality of light emitting diode (LED) strings. A LED driver adjusts the level of the output voltage so as to maintain the lowest tail voltage of the LED strings at or near a predetermined threshold voltage so as provide sufficient headroom voltages for current regulators for the LED strings. The LED driver operates in an operational mode and a calibration mode, which can be implemented in parallel with, or part of, the operational mode. During the calibration mode, the LED driver determines, for each LED string, a code value representative of the level of the output voltage necessary to maintain the tail voltage of the corresponding LED string at or near the predetermined threshold voltage. In the operational mode, the code values from the calibration mode are used to control the voltage source to provide an appropriate level for the output voltage.

    Abstract: Method for selective fabrication of high capacitance density areas in a low dielectric constant material and related structure are disclosed. In one embodiment, a first area of a dielectric layer is covered while a second area of the dielectric layer is exposed to a dielectric conversion source. The exposure causes the dielectric constant of the dielectric layer in the second area to increase. A number of interconnect trenches are etched in the first area of the dielectric and a number of capacitor trenches are etched in the second area of the dielectric. The interconnect trenches and the capacitor trenches are then filled with an appropriate metal, such as copper, and a chemical mechanical polish is performed. The second area in which the capacitor trenches have been etched and filled has a higher capacitance density relative to the first area.

    Abstract: A method is provided for forming an improved interconnect structure on a semiconductor body. A first metal layer is deposited on the semiconductor body. A sacrificial layer having a height is deposited on the first metal layer. The sacrificial layer and the metal layer are patterned to form separate metal lines with the sacrificial layer remaining on said metal lines. A look material is then deposited to fill the gaps bet n metal lines and to cover the sacrificial layer. The low-k material is then removed to a level within the height of the sacrificial layer. The sacrificial layer is then removed. A prove layer is deposited on top of the metal lines and the look material. A dielectric layer is deposited over the protective layer. The protective layer protects the low-k material from attack by chemicals utilized by subsequent process steps to etch vias in the dielectric layer, to strip photoresist, and to clean the vias. The protective layer is then selectively etched away to make contact between a via plug and the metal lines.
