摘要:
Methods of forming and processing semiconductor devices are described. Certain embodiments relate to the formation of self-aligned DRAM capacitors. More particularly, certain embodiments relate to the formation of self-aligned DRAM capacitors utilizing the formation of self-aligned growth pillars. The pillars lead to greater capacitor heights, increase critical dimension uniformity, and self-aligned bottom and top contacts.
