Zusammenfassung:A finFET trench circuit is disclosed. FinFETs are integrated with trench capacitors by employing a trench top oxide over a portion of the trench conductor. A passing gate is then disposed over the trench top oxide to form a larger circuit, such as a DRAM array. The trench top oxide is formed by utilizing different growth rates between polysilicon and single crystal silicon.
