Title: Method of sputtering a carbon overcoat as a protective film on magnetic recording disk
Inventor: JENG FU-WEN
IPC: G11B5/84
Filed: 1997-11-11
Granted: 2000-01-01
Abstract: The present invention provides a method of sputtering a carbon overcoat as a protective film on a magnetic recording disk, which is characterized in introducing hydrogen and nitrogen into the inert argon gas used in the sputtering process of the carbon overcoat wherein the hydrogen reacts with the carbon atoms in the carbon overcoat to form an SP3 covalent diamond structure and the nitrogen provides nitrogen atoms to the carbon overcoat to increase the surface energy of the carbon overcoat and act as a bridge of forming hydrogen bonding between the carbon overcoat and the OH groups in the lubricant layer. During the sputtering process, hydrogen and nitrogen will interact with each other such that an optimum carbon overcoat structure can be reached by controlling an appropriate ratio of argon/nitrogen/hydrogen in the gas mixture thereby increasing the abrasion resistance, and strengthening  thereof an the bonding between the carbon overcoat film and the lubricant layer, and reducing the thickness of the overcoat film, so that the magnetic recording disk exhibits a better magnetic performance and a prolonged operation life.

Title: Random binary number generator
Inventor: SOENEN ERIC
IPC: H03K3/0231
Filed: 1998-03-02
Granted: 2000-02-11
Abstract: A random number generator includes a plurality of fully differential amplifiers configured as a ring oscillator. The output of ring oscillator is input to a comparator/latch circuit for determining the zero crossing for the ring oscillator. The ring oscillator is a self-oscillating structure that has an oscillation frequency with jitter superimposed thereon. This jitter is a result of the internal thermal noise associated with the integrated circuits that are utilized to realize the amplifiers. Each of the amplifiers that make up the ring oscillator operate on a substantially constant current and are subsequently isolated from changes in the power supply. As such, the variations in the frequency therefor are caused solely by thermal noise. The comparator/latch circuit is operable to compare the difference on the output of the last stage of the ring oscillator and the output of the comparator/latch is then sampled by a CPU that is operated on a separate master clock. This allows the master clock, upon which the sample operation is based, to be completely separated from the ring oscillator.

Patent TW-399179-B (TW)
Title: Method and apparatus for compressing slice-oriented bitmaps
Inventor: RADEMACHER TIMOTHY JOHN
IPC: B41J5/30
Filed: 1998-02-05
Granted: 2000-07-21
Abstract: An improved printing system is provided that compresses bitmap print data by determining, per each slice of a swath of the printed page, which one of two different data compression techniques to more efficiently compresses each individual slice, then temporarily stores this compressed data in a memory circuit until needed by the printhead for actual printing of the final output in the form of print media.  When using slices containing seven (7) different words per slice, the present invention utilizes a single ""control bit"" of a ""control word"" to represent each of the data words of the slice.  Depending upon which type of compression technique is used, the control bit for each data word will be set to either Logic 1 or Logic 0, depending upon the value of the data word as compared to a pre-determined data word value that is chosen by the system, and which may be used in both types of data compression techniques.  After each slice has been analyzed by both types of data compression techniques, certain of the data words in the slice can be temporarily discarded, leaving behind less than seven (7) data words to represent that slice as compressed data.  This compressed data for each individual slice will be matched up with a ""control word"" that is made up of the individual control bits described above, thereby creating a relatively small data set that can be stored in memory in a space that would be less than the amount of memory required to store the uncompressed slices for the same print data.  Later, these (compressed) data sets (one per individual slice) can be decompressed according to the proper decompression technique, and the full print data is then restored just before printing by the printhead.  As part of the control word, a ""mode bit"" can be set to either binary value of Logic 1 or Logic 0, thereby indicating which of the two data compression techniques was initially used for that slice.  The two data compression techniques used are called a ""USE-X MODE"" and a ""REPEAT MODE.""

Abstract: A method and system for controlling the quality of handovers are disclosed in which a poor radio environment in a target cell is revealed prior to completion of the handover procedure. During the handover signaling phase, the output power of the mobile station of interest and the target cell's base transceiver station are reduced. Consequently, prior to completion of the handover, if the target cell has a poor radio environment (below a predetermined C/I or C/N), the handover attempt will fail, and the mobile station will revert and remain connected to the original cell.

Title: DRAM using oxide plug in bitline contacts during fabrication and its methods
Inventor: JENG SHIANG-YUAN
IPC: H01L21/8242
Filed: 1998-12-21
Granted: 2000-07-01
Abstract: The conventional DRAM structure with capacitor under bit line faces the puzzles about high step height difference and over-large photo-resistor photolithography aspect ratio. This invention discloses a memory structure, which has the flat upper plate structure and a region of the upper plate that is wider than the bit line contact window opening formed at the adjoined region of the top of the bottom plate and the bit line contact window. The step height difference in peripheral circuit and memory array does almost not exist. Because the oxide plug is formed during the fabrication of the bit line contact window and a thick oxide layer is deposited in the peripheral circuit at the same time, the puzzle of the known art is solved. Further, one layer of lightly doped poly-silicon is pre-deposited at the contact part of the bottom plate and the wafer substrate to prevent the electric leakage phenomenon from the bottom plate.

Abstract: A method and apparatus for monitoring process state using plasma attributes are provided. Electromagnetic emissions generated by a plasma are collected, and a detection signal having at least one frequency component is generated based on the intensity of the collected electromagnetic emissions; or, the RF power delivered to a wafer pedestal is monitored and serves as the detection signal. The magnitude of at least one frequency component of the detection signal then is monitored over time. By monitoring the magnitude of at least one frequency component of the detection signal over time, a characteristic fingerprint of the plasma process is obtained. Features within the characteristic fingerprint provide process state information, process event information and process chamber information. In general, any chemical reaction having an attribute that varies with reaction rate may be similarly monitored.
