摘要:
Sacrificial plugs for forming contacts in integrated circuits, as well as methods of forming connections in integrated circuit arrays are disclosed. Various pattern transfer and etching steps can be used to create densely-packed features and the connections between features. A sacrificial material can be patterned in a continuous zig-zag line pattern that crosses word lines. Planarization can create parallelogram-shaped blocks of material that can overlie active areas to form sacrificial plugs, which can be replaced with conductive material to form contacts.
