Title: Method for manufacturing ferroelectric optical nonlinear micro grid with two-dimensional periodic area inversion
Inventor: PENG LUNG-HAN
IPC: G02F1/355
Filed: 2003-05-02
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a ferroelectric optical nonlinear micro grid having two-dimensionally periodic area inversion.  <P>SOLUTION: A 1st metal electrode pattern is formed on nonlinear crystal, and a sample is heat-treated in an atmosphere of the Curie temperature to generate shallow layer area inversion for the 1st time in the atmosphere of the heat treatment; and a 2nd metal electrode pattern is formed on the nonlinear crystal and the crystal is applied with a voltage higher than its coercive force field to complete deep layer area inversion for the 2nd time through the electric field operation. Consequently, when the ferroelectric crystal is driven with the electric field to achieve the area inversion (domain inversion), the generation of a nucleation seed in an inversion area is deterred and longitudinal movement is controlled; and multi-frequency laser beams are generated in a time zone at the same time to obtain two-dimensional linear photon crystal having a spatial filtering function. Further, space charges are used for shielding against an edge electric field below an electrode pattern. Further, the nucleation seed density of area inversion is controlled through an oxide layer electrode to manufacture a two-dimensional ferroelectric grid structure in an arbitrary geometric shape.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Thus, the reduction in the potential at the intermediate connecting points of the FETs 101 to 116 can be suppressed. As a result, the processable power can be increased beyond that of the conventional device and apparatus. Moreover, since the reduction in the potential at the intermediate connecting points of the FETs 101 to 116 can be suppressed, deterioration in the distortion characteristic and isolation characteristic caused by the reduction in the voltage at the intermediate connecting points of the FETs 101 to 116 can be suppressed and excellent high frequency characteristics can be obtained.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for detecting a bit error in a maskable content addressable memory.  <P>SOLUTION: Parity and mask bits are stored in a RAM connected to a CAM (content addressable memory). Upon CAM query matches, reference parity and mask bits stored in an address outputted by the CAM are outputted from the RAM.

In absence of a CAM or RAM bit error, the reference parity bits from the RAM and the parity bits generated from the masked query data will match. If there is a CAM or RAM bit error, an error will be detected since the two parity bit sets will not match.  <P>COPYRIGHT: (C)2004,JPO
