Patent number: 8066430Abstract: The invention provides a method and a device for determining the temperature of a semiconductor substrate. A resonance circuit (110) is provided on the semiconductor substrate and is formed by a junction capacitor (11) and an inductor (12). The substrate is placed on a holder and the resonance circuit (110) is irradiated with electromagnetic energy of an electromagnetic field (5) generated by a radiation device (200). A resonance frequency of the resonance circuit (110) is determined by detecting an effect of the resonance circuit (110) on the irradiated electromagnetic field (5), and a temperature of the semiconductor substrate is determined as a function of the resonance frequency. The method and device according to the invention provide for a more accurate determination of the temperature of the semiconductor substrate due to an increased sensitivity to the temperature of the junction capacitor (11).Type: GrantFiled: April 19, 2007Date of Patent: November 29, 2011Assignee: NXP B.V.Inventors: Srdjan Kordic, Meindert M.

Patent number: 7951729Abstract: A passivating coupling material for, on the one hand, passivating a dielectric layer in a semiconductor device, and on the other hand, for permitting or at least promoting liquid phase metal deposition thereon in a subsequent process step. In a particular example, the dielectric layer may be a porous material having a desirably decreased dielectric constant k, and the passivating coupling material provides steric shielding groups that substantially block the adsorption and uptake of ambient moisture into the porous dielectric layer. The passivating coupling materials also provides metal nucleation sides for promoting the deposition of a metal thereon in liquid phase, in comparison with metal deposition without the presence of the passivating coupling material. The use of a liquid phase metal deposition process facilitates the subsequent manufacture of the semiconductor device.Type: GrantFiled: February 12, 2010Date of Patent: May 31, 2011Assignee: NXP B.V.Inventors: Janos Farkas, Srdjan Kordic, Cindy Goldberg
