  • Publication number: 20240136175
    Abstract: The present invention relates to an auxiliary precursor, a thin film precursor composition, a method of forming a thin film using the thin film precursor composition, and a semiconductor substrate fabricated using the method. The present invention provides the thin film precursor composition including a thin film precursor compound and a compound having a predetermined structure that exhibits reaction stability as the auxiliary precursor. By using the thin film precursor composition in a thin film deposition process, side reactions may be suppressed, and thin film growth rate may be appropriately controlled. In addition, since process by-products are removed from a thin film, even when a thin film is formed on a substrate having a complicated structure, step coverage and the thickness uniformity and resistivity characteristics of the thin film may be greatly improved.

  • Publication number: 20110204023
    Abstract: Disclosed is a multi-inductively coupled plasma reactor and method thereof. In a multi-inductively coupled plasma reacting method, an etching method to increase a specific portion of a substrate to be processed includes etching a specific portion of a substrate to be processed; and depositing a passivation layer on a surface of the specific portion etched, wherein the etching and depositing steps are repeatedly proceeded, and one of both steps is executed when there is plasma formed by a central plasma source and a peripheral plasma source. According to the multi-inductively coupled plasma reactor and method thereof of the invention, it is possible that plasma is uniformly processed on the entire area of the substrate since the central plasma source and the peripheral source are provided separately.

  • Patent number: 6031802
    Abstract: An improved data writing density judging apparatus and method for a disc capable of judging a writing density of a disc by detecting an amount of cross talk or detecting a tracking error signal. Cross talk is detected when a disc track is scanned by a beam. A tracking error signal is detected when a pick-up member jumps a certain track while the pick-up member moves across a disc track. The improved apparatus and method computes a ratio between a minimum value and a maximum value of an envelope signal based on the detected amount of cross talk a writing density can be determined. The improved apparatus and method also converts a tracking error signal which is a high frequency analog signal into a digital signal that is used to compute a time required for a pick-up member to jump a certain track. Based on the computed time which is compared with a reference value, a writing density of a disk can also be determined.
