Patent number: 9484409Abstract: A semiconductor device includes a semiconductor substrate including a well dopant layer having a first conductivity type, a gate electrode on the well dopant layer, a channel dopant layer in the well dopant layer and spaced apart from a top surface of the semiconductor substrate, a channel region between the gate electrode and the channel dopant layer, and source/drain regions in the well dopant layer at both sides of the gate electrode. The channel dopant layer and the channel region have the first conductivity type. The source/drain regions have a second conductivity type. A concentration of dopants having the first conductivity type in the channel dopant layer is higher than a concentration of dopants having the first conductivity type in the channel region. The semiconductor device may be used in a sense amplifier of a memory device.Type: GrantFiled: September 4, 2015Date of Patent: November 1, 2016Assignee: Samsung Electronics Co., Ltd.Inventors: Eun-Sun Lee, Junhwa Song, Ji Hun Kim, Jeonghoon Oh

Patent number: 7952907Abstract: An FRAM device includes first ferroelectric capacitors, second ferroelectric capacitors, first plate lines and second plate lines. The first ferroelectric capacitors can be connected between word lines and bit lines. The second ferroelectric capacitors can be connected between the word lines and bit line bars. The first plate lines can be connected to upper electrodes of the first ferroelectric capacitors. The second plate lines can be connected to upper electrodes of the second ferroelectric capacitors. Thus, the first ferroelectric capacitors connected to the bit lines and the second ferroelectric capacitors connected to the bit line bars can be connected to the different plate lines, so that data can be output from any one of the bit line and the bit line bar. As a result, a layout of a core region can be simplified.Type: GrantFiled: February 19, 2009Date of Patent: May 31, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Eun-Sun Lee, Young-Min Kang
