摘要： Embodiments relate to a single poly type EEPROM and a method for manufacturing an EEPROM. According to embodiments, a single poly type EEPROM may include unit cells. A unit cell may include a floating gate at a side of a control node formed on and/or over a semiconductor substrate having an activation region and a device isolation area, not overlapping a device isolation region but overlapping only a top of the activation region. A select gate may be formed on and/or over a top of the activation region. According to embodiments, a ratio of a capacitance of a control node side to a capacitance of a bit line side may increase, which may improve a coupling ratio. According to embodiments, a junction capacitance may be maximized by not doping the floating gate with an impurity, which may allow for a reduction in chip size by securing design margins.
