Title: Amplified sensor arrays
Inventor: HODGSON CRAIG W
IPC: H04B10/17
Filed: 1997-07-11
Granted: 2000-03-01
Abstract: The present invention significantly improves the signal to noise ratio (SNR) in a passive optical array comprising sensors located in rungs between a distribution bus and a return bus. Erbium-doped optical fiber amplifiers are included in the buses proximate to each rung coupling to offset the coupler splitting losses. The gains of the amplifiers are selected to offset losses due to the couplings. The overall SNR can be maintained without significant degradation even for large numbers of sensors. In one aspect of the present invention, the amplifiers are located along the distribution and return buses directly after the couplers, except for the last coupler. In a second aspect, the amplifiers are located directly before each coupler. The optical amplifiers preferably are made of short lengths of erbium-doped fiber spliced into the distribution and return buses. Improvements can be made to the SNR when the distribution bus coupling ratios are set at optimal values. The value of the optimal coupling ratio depends upon the amplifier configuration, the excess loss and other configurations parameters. In preferred embodiments, sensors are grouped into parallel configurations in the rungs between the distribution and return buses to increase the number of sensors without a corresponding increase in the number of amplifiers and with an improvement in system performance. The number of sensors per rung is optimized to provide a low noise figure (NF) or a high SNR for each sensor in the array within a reasonable pump power budget.

Title: Manufacturing method of a read-only memory device
Inventor: LIN MING-YI
IPC: H01L21/00

Granted: 2001-05-16
Abstract: The present invention discloses a method for manufacturing a semiconductor device, by which the anti-corrosiveness of a read-only memory code product during wafer stage can be elevated and the production cost can be reduced. The method at least includes providing a semiconductor substrate, and covering a protective photoresist over the substrate before the clients' instruction is received, that is, before a read-only memory code mask is provided. The photoresist can obviate a risk of corrosion of the barrier layer (such as titanium/titanium nitride layer) formed on the surface of the substrate and further elongate the standby expiration date of semi-finished products during wafer stage. Moreover, if the client agrees, a COB pad mask can be merged into a read-only code mask so that the production cost of a layer of the patterned photoresist can be saved because only one step of defining pattern is needed.
