IPC: G11B20/10
Filed: 2000-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a signal recording circuit that can reduce a reproduction jitter caused by low frequency components included in the modulation signal of DC-free modulation. SOLUTION: The signal recording circuit that records the modulation signal of DC-free modulation on a recording medium is equipped with a low frequency component extraction means 24 that extracts the low frequency components of modulation signal and an amplitude modulation means 36 that amplitude- modulates the said modulation signal in response to the low frequency components extracted by the low frequency component extraction means. When the signal reproduced from the recording medium is binarized in order to record the output signal of the amplitude modulation means 36 on the recording medium, since the above-mentioned amplitude modulation components and the low frequency components included in the reproduced signal cancel each other, the reproduction jitter can be reduced.

Title: Method and device for forming sputtered dope-finished seed layer
Inventor: PAVATE VIKRAM
IPC: H01L21/28
Filed: 2000-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for forming a deped layer on a substrate and improving the uniformity of the subsequent deposition thereon. SOLUTION: A doped target of an electrically conductive material is used, and, a layer is deposited by a sputtering process such as PVD or IMP PVD. An electrically conductive material such as copper is alloyed with a dopant such as phosphorus, boron, indium, tin, beryllium or their combination to improve the uniformity of the deposition of the doped layer onto the surface of the substrate and also to reduce the oxidation of the electrically conductive material. When the dopant such as phosphorus is added, the surface of the electrically conductive material is stabilized, and the surface diffusing ratio is made low. The tolal surface diffusing ratio or copper reduces a tendency that the same is agglomerated or is made uncontinuous, by which an electrically conductive film is more smoothly deposited to reduce the located agglomeration of the electrically conductive material.
