IPC: H05K3/06
Filed: 2002-11-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide an etchant giving a good etching factor by incorporating thereinto as an additive an adjusted organic compound for preferentially suppressing side etching, and an etching method.  <P>SOLUTION: The etchant is constituted of cupric chloride, hydrochloric acid, and an organic compound such as a surfactant, an antioxidant or the like. The organic compound in the etchant has a diffusion coefficient adjusted to fall within the range of 0.1-1.00×10<SP>-5</SP>cm<SP>2</SP>/sec, and therefore is preferentially adsorbed on an etching side face of a metallic material to be processed thereby suppressing etching in a horizontal direction. Particularly, the etchant attains etching processing of a large etching factor (EF) in pattern etching of an opening width of at most 20 μm. The metallic material is etched using the etchant.  <P>COPYRIGHT: (C)2004,JPO

Title: Ferroelectric memory and method for reading data therefrom
Inventor: AOKI MASAKI
IPC: G11C17/02
Filed: 2002-11-25
Abstract: <P>PROBLEM TO BE SOLVED: To surely read data even when the reading margin of data written in a manufacturing process is lowered in a subsequent heat process.  <P>SOLUTION: A second reading operation is executed to read data from a dummy memory cell before a first reading operation for reading data from a real memory cell by using a reference memory cell. By the second reading operation, the residual polarized value of the ferroelectric capacitor of the reference memory cell reduced by the heat treatment or the like of the manufacturing process is returned to an original value before reading access to the real memory cell. Thus, in the subsequent first reading operation, the data of the real memory cell are correctly read. As a result, for example, data stored in a ROM area are surely read from the ferroelectric memory having the ROM area in which the data are written beforehand in the testing step or the like of the manufacturing process.  <P>COPYRIGHT: (C)2004,JPO
