Inventor: VOLLKOMMER FRANK DR
IPC: H05B41/30
Filed: 1998-08-06
Granted: 2003-01-21
Abstract: A method for producing pulsed-voltage sequences for the operation of discharge lamps (8) by means of a pulsed discharge which is impeded dielectrically provides for some of the required pulse peak values to be replaced by an offset DC voltage component (UDC(t)). This has, inter alia, the advantage that correspondingly less EMI is generated when the pulsed-voltage sequences (Up(t)) are produced. It is also provided for a portion of the electrical real power injected into the discharge predominantly throughout the duration of the voltage pulses to be injected on the basis of the offset DC voltage (UDC(t)). For this purpose, a circuit arrangement provides a series circuit comprising a pulse circuit (1) and a DC voltage circuit (2), in which case the pulse circuit (1) can be designed for a power level that is lower than that in the prior art.

Title: Post-etch treatment for a dielectric etch process
Inventor: OU-YANG HUI
IPC: H01L21/311
Filed: 2000-06-16
Granted: 2004-03-01
Abstract: The present disclosure pertains to a post-etch treatment which is performed after a dielectric etch process. Using the method of the invention, byproducts formed on the sidewalls of contact vias during the dielectric etch process can be removed efficiently. The method of the invention also reduces or eliminates the problem of polymer accumulation on process chamber surfaces. Typically, after the etch of a dielectric material to define pattern or interconnect filling spaces, a series of post-etch treatment steps is performed to remove residues remaining on the wafer after the dielectric etch process. According to the method of the present invention, a post-etch treatment method including one or more steps is performed after the dielectric etch process, preferably within the same processing chamber in which the dielectric etch process was performed. The post-etch treatment method comprises exposing a semiconductor structure to a plasma generated from a source gas comprising oxygen, a nitrogen-comprising gas, and a reactive gas comprising hydrogen, carbon, and fluorine. Two optional steps, a flushing step prior to the post-etch treatment and a cleaning step subsequent to the post-etch treatment, can be performed, respectively, before and after the post-etch treatment-for the purpose of enhancing the fluorine and byproduct removal and post-etch chamber cleaning.

Title: Embedded intrusion detection system

Filed: 2000-05-30
Granted: 2002-02-21
Abstract: The present embedded intrusion system is applied to protect the security of a website by detecting the unauthorized or over-right operation. The technique disclosed by the present invention relates to a host-based intrusion system, that is, an intrusion system using the event record of the host as the major monitoring item. The main object of the present invention is to eliminate the drawback in that the existence of the conventional host-based intrusion detection system is easily found by the hacker (so that the security is negatively influenced). The method is to make a system status collection module perform a non-continuous monitor in the server computer in a manner almost the same with the ordinary operation, such that even an experienced hacker can hardly find the existence of the system status collection module, thereby increasing the difficulty for the hacker to intrude the system.

Title: High-precision digital-to-analog converting circuit
Inventor: KINUGASA NORIHIDE
IPC: H03M1/78
Filed: 2000-08-17
Granted: 2002-05-11
Abstract: A digital-to-analog (D/A) converting circuit comprises the followings. A high-order D/A converting circuit portion (100) outputs the first voltage (Va) and the second voltage (Vb), which are generated by D/A converting the high-order 5 bits of a 13-bit input code to the first and the second output nodes (11, 12), respectively, after passing through two buffers (10a, 10b) of the same characteristics. A low-order D/A converter circuit portion (200) outputs a voltage, which is generated by D/A converting the low-order 8 bits of the input code through the use of the voltages at the two output nodes as the reference voltages of an R-2R ladder circuit (201) to the third output node (13). A sample-and-hold portion (250) selectively samples and holds, depending on the value of the input code, a voltage of the third output node (13), which is the D/A conversion output of the 13-bit input code. An output unit (300) amplifies the sampled and held D/A conversion voltage by a gain through the use of an arbitrary voltage (Vc) as its center. Thus, under the condition of having a large number of conversion bits, it is able to realize a D/A converting circuit that can output a desired analog voltage with a high precision by using a small-size chip area.

Title: Document compression method
Inventor: CHEN SHR-HAU
IPC: H04N1/41
Filed: 2001-04-04
Granted: 2002-12-01
Abstract: The invention relates to a document compression method. Because a scanned document with pictures and texts occupies a huge memory space, the document is divided and classified into image and text to facilitate the compression processing. After identifying document as text file and/or image file, it is able to further effectively achieve saving of compression space, and hence, document can be further divided into different image categories. The invention intends to use mechanism such as binary tree to distinguish the image patterns to ease up jobs like image division and image classification. Further, a compression is performed in accordance with the image pattern category to enhance the compression rate and storage space saving required by digital image. As the invention increases the compression ratio, the compressed document obtained using the method of the invention has better visual effect than the regular compressed document in terms of visual effect on text part.
