Title:
CAPACITIVE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2017/159283
Kind Code:
A1
Abstract:
In the present invention, a first lower electrode (21) and a second lower electrode (22) are disposed adjacent to each other in a Y-axis direction on a substrate (1). A first dielectric layer (31) is formed on the first lower electrode (21), and a second dielectric layer (32) is formed on the second lower electrode (22). A first upper electrode (41) and a second upper electrode (42) are disposed adjacent to each other in an X-axis direction on the first dielectric layer, and a third upper electrode (43) and a fourth upper electrode (44) are disposed adjacent to each other in the X-axis direction on the second dielectric layer. Interlayer conductors (51, 52, 53, 54) contact the upper electrodes (41, 42, 43, 44), respectively. A first connection conductor (61) connects the second interlayer conductor (52) and the fourth interlayer conductor (54). The third upper electrode (43) is disposed adjacent to the first upper electrode (41) in the Y-axis direction, the fourth upper electrode (44) is disposed adjacent to the second upper electrode (42) in the Y-axis direction, and the first connection conductor (61) extends in the Y-axis direction.
