Abstract:
A semiconductor device and method of manufacture are provided which help to support contacts while material is removed to form air gaps. In embodiments a contact is formed with an enlarged base to help support overlying portions of the contact. In other embodiments a scaffold material may also be placed prior to the formation of the air gaps in order to provide additional support.
