Patent number: 7790606Abstract: A method of forming an interconnect structure in a semiconductor device in which via holes (62) defined in a dielectric layer are filled with a filler material (64), such as a porogen material, before a further dielectric layer (66) is deposited thereover. Trenches (72) are formed in the further dielectric layer and then the filler material exposed thereby in the via holes is removed. The method provides a robust process which affords improved via and trench profile control.Type: GrantFiled: October 5, 2007Date of Patent: September 7, 2010Assignee: NXP B.V.Inventor: Roel Daamen

Patent number: 7790480Abstract: A process (300) is disclosed to measure predetermined wavelength reflectance spectra of a photo resist coated wafer (305,310,315,320) at a nominal thickness. After coating, the predetermined wavelength reflectance (325,330) is measured and the peak heights and valleys in the vicinity of the predetermined wavelength are tabulated. The relative swing ratio is computed (335) as the average peak height of the spectra at the exposure wavelength. This relative swing ratio is then compared to similar computations on other processes to determine which provides the best critical dimension (CD) control.Type: GrantFiled: October 19, 2004Date of Patent: September 7, 2010Assignee: NXP B.V.Inventor: David Ziger

Patent number: 7791059Abstract: An electric device has an electrically switchable resistor (2?) comprising a phase change material. The resistance value of the resistor can be changed between at least two values by changing the phase of the phase change material within a part of the resistor called the switching zone (12?) using Joule heating of the resistor. The device comprises a body (24?) encapsulating the resistor, which body comprises at least two abutting regions (26?, 28?) having different thermally insulating properties. These regions form a thermally insulating contrast with which the dimension of the switching zone can be determined without having to alter the dimensions of the resistor. Such a device can be used in electronic memory or reconfigurable logic circuits.Type: GrantFiled: March 21, 2007Date of Patent: September 7, 2010Assignee: NXP B.V.Inventors: Frisco J. M.

Patent number: 7791515Abstract: A receiver uses a sigma delta ADC (126) and an adaptable digital filter (132). Detector circuitry detects information about unwanted parts of the signal from an oversampled digital signal, before the filtering, and feeds forward the detected information to the filter, to adapt the filter. By feeding forward the detection information, rather than feeding back an output of the filter, the adaptation can respond much more quickly to rapid changes in the unwanted interference. This enables reduced filtering to save power when interference is low, without risking a sudden increase in interference causing an avalanche of errors before the filter can be adapted correctly. The filter receives the oversampled digital signal combines decimation and channel filtering in one stage.Type: GrantFiled: October 24, 2005Date of Patent: September 7, 2010Assignee: NXP B.V.Inventor: Robert Fifield

Publication number: 20100219892Abstract: The present invention relates to a circuit configuration for detecting and rapidly limiting large current increase based on high current injection at the output terminal (out). In particular, a gate-controlled switching device (PO), controlled by a driver circuit (40) through a low resistive element (RO) and passed through by a current overshoot, will be alternatively driven by the circuit of the present invention while having its control terminal charged by the high injected current. Thus, when large voltage increase generated by a steep front impulse with a positive slope is detected by the capacitor (C) and transmitted to the gate terminal (GateN), the circuit of the present invention bypasses the driver circuit (40) while injecting a significant current peak issued from the transistor (P3) towards the gate terminal (GateP) of the gate-controlled switching device (PO), whereas the capacitor (C) is discharging very slowly through the gate terminal (GateN).Type: ApplicationFiled: July 17, 2006Publication date: September 2, 2010Applicant: NXP B.V.Inventor: Guillaume De Cremoux

Publication number: 20100223486Abstract: I2C clock generators are implemented using a variety of methods. Using one such method, a method is implemented using logic circuitry arranged in a state machine to control the clock signal (110) on the I2C bus. A first state (202) of the state machine determines whether to effect a clock stretching delay. A second state (206) of the state machine determines whether the I2C bus is configured to run in a standard clock mode or in another one of multiple faster clock modes. A third state (210) of the state machine drives the clock signal in one binary logic state for more than about 0.5 microseconds before allowing the clock signal (110) to be driven in the other binary logic state and allowing the clock signal to remain in the other binary logic state for more than about 0.5 microseconds.Type: ApplicationFiled: March 31, 2007Publication date: September 2, 2010Applicant: NXP B.V.Inventor: Amrita Deshpande
