Title: Method for making all-fiber interleaver with continuous fiber arm
Inventor: DENT JYH-REN
IPC: G02B6/34
Filed: 2001-12-31
Granted: 2003-04-01
Abstract: A method for forming an all-fiber, low-loss interleaver to obtain a predetermined optical channel spacing. The interleaver features at least one arm formed with and continuous between couplers of a Mach Zender type arrangement. The interleaver is formed by first analytically determining Δθ, the difference in optical lengths between the two optical paths between the couplers. The difference is then fine-tuned by the application of heat and tension to a jacket-stripped segment of the continuous fiber arm as a DWDM signal is observed at the output of the interleaver.

Title: Method for manufacturing semiconductor device
Inventor: NAMBU HIDETAKA
IPC: H01L21/311
Filed: 2002-03-01
Granted: 2003-08-11
Abstract: A hard mask is formed on an organic interlayer film and a resist pattern is formed on the hard mask. A first pattern of the hard mask is formed by etching the hard mask using said resist pattern as a mask and a second pattern of the organic interlayer film is formed by etching said organic interlayer film using said first pattern as a mask. Said organic interlayer film is etched using a gas for the etching and is etched (a first etching) by applying a first pressure on the gas and then etched (a second etching) by applying a second pressure on the gas. The second pressure is lower than the first pressure. The gas includes N2 gas. In this case, the first etching is performed by etching gas of a first concentration on the N2 gas, and then the second etching is performed by etching gas of a second concentration on the N2 gas. The second concentration is lower than the first concentration. By changing the gas pressure and the N2 concentration, the grooves having excellent perpendicularity can be formed in the organic interlayer film.

Title: Method of polycarbonate preparation by solid state polymerization
Inventor: MCCLOSKEY PATRICK JOSEPH
IPC: C08G64/06
Filed: 2002-07-11
Granted: 2004-06-21
Abstract: Solid state polymerization of partially crystalline polycarbonate oligomers bearing ester-substituted terminal groups occurs at useful reaction rates despite their high level of endcapping. Partially crystalline polycarbonate oligomers having ester substituted terminal groups may be obtained in a single step by reaction of an ester substituted diaryl carbonate such as bis-methyl salicyl carbonate with a dihydroxy aromatic compound such as bisphenol A in the presence of a transesterification catalyst such as sodium hydroxide. Alternatively, amorphous oligomeric polycarbonates incorporating ester-substituted end groups may be obtained through careful control of the melt reaction conditions. The amorphous oligomeric polycarbonates are crystallized upon exposure to solvent vapor and subsequently undergo solid state polymerization at synthetically useful reaction rates.

Title: Dual-layered microstrip reflective plane antenna structure
Inventor: JANG JR-NAN
IPC: H01Q19/195
Filed: 2003-01-17
Granted: 2004-06-01
Abstract: The present invention relates to a dual-layered microstrip reflective plane antenna structure, which is mainly to form an antenna unit and a corresponding phase-delay circuit unit overlapped for a certain distance on the opposed surfaces of the first dielectric layer respectively. The second dielectric layer is adjacent to the first dielectric layer. By adjusting the said overlapping distance, side length of antenna unit, and the dielectric constant and thickness of the two dielectric layers, a better gain bandwidth can be obtained. In addition, by selecting a lower dielectric constant, the well-known surface wave phenomenon generated by increasing the thickness of structural layer can be reduced by selecting a lower dielectric constant. At the same time, the second dielectric layer is close to the ground layer as possible in the present invention for creating good grounding effect, thereby the radiation generated by the phase delay circuit unit can be reduced.
