A system for controlling and monitoring operations of a chemical dispense system from a remote location is disclosed. The chemical dispense system includes a formulator for preparing a chemical product using one or more component chemical concentrates. The chemical dispense system also includes an allocator for managing the distribution of formulated chemical products to a point-of-use such that the formulated products are distributed to the point-of-use by a specified plan or sequence. The allocator may also be used to manage the formulation of chemical products such that the chemical products are formulated based on a plan or sequence. The chemical dispense system includes a communications system that enables system operators to control and monitor allocation and/or formulation operations from a remote location. A method for remotely monitoring and controlling operations of the chemical dispense system is also disclosed.

Fault-tolerant systems and methods to process and correct input spelling errors for non-Roman based languages such as Chinese, Japanese, and Korean (CJK) are disclosed. The method may be applied to a Chinese input method using pinyin. For example, the method may generally include receiving a pinyin input representing characters in Chinese, the input having at least one original pinyin, identifying potentially incorrect pinyins in the input, expanding each potentially incorrect pinyin to at least one additional alternative pinyin, each pair of potentially incorrect and corresponding alternative pinyin having a proximity measurement, converting each pinyin in the input and each alternative pinyin to Chinese characters, computing likelihoods of possible conversions of the pinyin input to Chinese characters, each possible Chinese conversion being a combination of the converted original and/or alternative pinyins of the input, the probabilities being based on the proximity measurement and optionally on a context of the possible Chinese conversion, and determining a most likely Chinese conversion from the possible conversions.

A BFSK demodulator comprises a three-channel frequency-to-voltage converter, an information signal inputting the first-channel frequency-to-voltage converter, a converted information signal inputting the second-channel frequency-to-voltage converter, wherein outputs of first and second channel frequency-to-voltage converter are connected with a capacitor, a output voltage signal produced by the first and second frequency-to-voltage converters and the capacitor, inputting into a positive terminal of the comparator after high frequency noise filtering through a first low-pass filter, a carrier signal inputs into the third-channel frequency-to-voltage converter; and an output from the third-channel frequency-to-voltage converter connected to a capacitor; and a reference voltage signal is produced after high frequency noise filtering through a second low-pass filter, producing a demodulated signal after comparing the information voltage signal with the reference voltage.
摘要:
A method for fabricating a dielectric layer provides for use of a carbon source material separate from a halogen source material when forming a carbon and halogen doped silicate glass dielectric layer. The use of separate carbon and halogen source materials provides enhanced process latitude when forming the carbon and halogen doped silicate glass dielectric layer. Such a carbon and halogen doped silicate glass dielectric layer having a dielectric constant greater than about 3.0 is particularly useful as an intrinsic planarizing stop layer within a damascene method. A bilayer dielectric layer construction comprising a carbon and halogen doped silicate glass and a carbon doped silicate glass dielectric layer absent halogen doping is useful within a dual damascene method.
摘要:
A new method is provided to replace tungsten plugs for wafers that trigger the WCVD backside alarm. In this new rework process, the original TiN glue layer is sputter etched back and a new (“fresh”) 100-Angstrom thick layer of TiN is deposited. The new tungsten plug is created over the top surface of the refreshed glue layer.
