Title: Alternating gain and phase control system and method
Inventor: GHANADAN REZA
IPC: H03F1/32
Filed: 2000-08-18
Abstract: PURPOSE: An alternating gain and phase control system and method are provided to provide a gain and a system for adjusting a relative phase and gains between signals to be connected in a distortion reduction system. CONSTITUTION: A gain and phase control system performs a gain (or phase) adjustment based on the results of a previous gain (or phase) adjustment after an intervening phase (or gain) adjustment. A gain adjustment is based on the results of a previous gain adjustment rather than on the results of an intervening phase adjustment. A phase adjustment is based on the results of a previous phase adjustment rather than the results of an intervening gain adjustment. As such, the above-mentioned increase in error signal does not occur because a gain adjustment is based on the results of the previous gain adjustment, and a phase adjustment is based on the results of the previous phase adjustments. In accordance with another aspect of the present invention, the gain and phase control system makes a gain (or phase) adjustment in parallel with detecting the results from a previous phase (or gain) adjustment, thereby taking advantage of the delay between adjustment and detection of the resulting error signal to improve the convergence rate. For example, the gain and phase control system can perform single alternating gain and phase adjustments and make a gain (or phase) adjustment while detecting the error signal resulting from a preceding phase (or gain) adjustment. When the error signal resulting from the gain (or phase) adjustment is being detected, the gain and phase control system makes a phase (or gain) adjustment using the results detected from the preceding phase (or gain) adjustment.

Abstract: PURPOSE: A method for repairing a mask and a mask repaired by the method are provided, to restore a mask without deteriorating lithographic characteristics and without increasing the degree of scattering induced by the repaired regions to an impermissible degree. CONSTITUTION: A SCALPEL (Scattering Angular Limited Projection Electron Lithography) mask has films whose masking regions generally overlap each other. In order to modify a transparent defective part such as a spatial area in the masking regions, a gallium-containing carbon material is deposited. In this process, styrene is given an impact with a gallium entity beam. The final thickness of the deposition is made sufficiently large to cause the scattering of incident electrons equivalent to the scattering of electrons having the intrinsic energy induced from the films or masking regions in accordance with the kind of the transparent defective part to be modified. One of the regions comprises tungsten or silicon nitride.
