Filed: 1986-10-20
Abstract: PURPOSE:To improve efficiency of cutting by projecting a laser scanning locus to the outside of a hole shape line near the point where the cutting start point and cutting end point coincide with each other on the laser scanning locus, then executing cutting. CONSTITUTION:The scanning locus L1 inner by the radius (r) of the processing spot than the line L of the hole shape to be processed is preset. The laser scanning locus starting from the processing start point O arrives linearly at one point A on the line L of the hole shape and progresses on the scanning locus L1 set in the curved direction from the substantial processing point A1, thereby executing boring. The scanning locus projects to the outside of the line L of the hole shape in a virtual circle N from the point B and the scanning is executed when the scanning locus L1 returns to the point B near the first point A, then the scanning is executed. A projecting part C1 reaching the point B1 is generated at this time, but the scanning locus is so set that said part does not enter the inside of the line L of the hole shape. The need for processing the inside of the line after the dislodgment of a dislodging member M1 is eliminated and, therefore, the efficiency of the working is improved.

Title: Ferroelectric memory and reading method therefor
Inventor: EMORI TAKAYUKI
IPC: H01L29/788
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous inversion of data by applying a read voltage within such range as causing no inversion of polarization in a ferroelectric film. SOLUTION: A gate insulation film 21, a lower electrode 31, a ferroelectric film 22 and an upper electrode 32 are formed sequentially on a substrate 10. When a data is read out from such ferroelectric memory, a read voltage VR is applied between the upper electrode 32 and a drain 12 utilizing the residual polarizaiton of ferroelectric film 22 and '1' or '0' is determined depending on the fact whether a current flows between the source 11 and the drain 12 or not. In this regard, the read voltage VR is applied within such range as causing no inversion of polarization in the ferroelectric film. For example, 0V is applied to the gate 31, source 11 and substrate 10 and a voltage VR, satisfying a formula |VR|< (CF+Co)/Co}.|Vc|, is applied to the drain 12.  In the formula, CF is the capacitance (fF) of ferroelectric film 22, Co is the capacitance (fF) between the lower electrode 31 and the drain 12, and Vc is the coercive voltage (V) of ferroelectric film 22.
