Abstract:
PURPOSE: A deep N-well guard ring and a 3D integrated circuit including the same are provided to reduce power noise of the 3D integrated circuit due to high frequency signals by connecting the deep N-well guard ring located around the through silicon via to a power source. CONSTITUTION: An N-well region(550) is formed on one side of a semiconductor chip and is formed around a through silicon via(510). An N type impurity region(540) is formed on the N-well region. A guard ring electrode is formed on the N type impurity region. A depletion region(560) is formed around the N-well region of the semiconductor chip.

PURPOSE: A current measuring element for a three dimensional integrated circuit, a method for manufacturing the same, and a current measuring circuit including the same are provided to reduce the size of a current measuring element by forming a coil type conductive path around a conductive pattern in a redistribution layer. CONSTITUTION: A current measuring element(100) comprises a first conductive pattern(110) and a second conductive pattern(120). The first conductive pattern is formed on a first side of a substrate. The second conductive pattern is formed in a redistribution layer located in a second side of the substrate to constitute a coil type conductive path around the first conductive pattern. The current measuring element measures the intensity of input current based on induced current formed in the coil type conductive path in response to the input current flowing in the first conductive pattern.
Abstract:
PURPOSE: A 3D integrated circuit including a power pin and a method for arranging the power pin are provided to reduce inductance of power pins by arranging pins with the same polarity in a row. CONSTITUTION: First power pins(751,752,753) are arranged on one or more circuit boards(710,720,730,740) with a first interval in a first direction(D1). Second power pins(761,762,763) are separated from the first power pins in a second direction which is orthogonal to the first direction and are arranged on one or more circuit boards with a second interval in the first direction. The polarities of the second power pins are opposite to the polarities of the first power pins. The first interval is equal to the second interval.
