Abstract: PURPOSE: To improve reliability even if a capacitor electrode is thinned and increase capacitance by bringing a capacitor electrode into contact through a conductor layer and forming it to extend on a bit line. CONSTITUTION: First and second conductor layers 2-8, 2-9 are pattern-formed in each semiconductor region and a bit line in contact with the second conductor layer 2-9 is formed. Thereafter, layer insulation films 2-13, 2-15 are deposited on a bit line and a contact hole is provided to the layer insulation films 2-13, 2-15 to exposed the first conductor film 2-8 partially. A capacitor electrode 2-16 is formed to form an electrical contact to the first conductor layer 2-8 and to extend on a bit line. That is, a capacitor electrode does not come into direct contact by lowering to a semiconductor region but come into contact through the conductive layer 2-8 and is formed to extend on a bit line. Capacitance can be increased in this way.

Title: Resolution converter
Inventor: HORIE HITOSHI
IPC: G06T3/40
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To reduce number of times of product sum arithmetic operations by deciding a converted picture element without calculation of a value of the converted picture element when a reference picture element indicates a specific predetermined image pattern. SOLUTION: Based on a theory that when all reference picture elements are '0' or '1', a converted picture element is definite without any filter calculation, since a rate of black level picture elements in a document image is small, it is detected that all reference picture elements are '0' and in this case, the filter calculation is omitted. A pattern detection circuit provides an output of an output signal '0' when all the reference picture elements are '0' and provides an output of an output signal '1' when all the reference picture elements are '1'. In this case, a pattern detection signal PS is set to an on-state. When the pattern detection signal PS is on, a selector 17 selects an output of the pattern detection circuit. That is, the value of the pattern detection signal PS is checked and when it is on, the filter calculation is omitted.
