SEMICONDUCTOR MEMORY DEVICE

摘要

PURPOSE: The semiconductor memory device reduces the misalign generation between the contact. The resistivity fault between the contact, and the short failure and the not-open fault are prevented. CONSTITUTION: A word line having the first effective pitch(P1) is located on surface unit active areas. The bit line having the first effective pitch is located on surface word lines. The first pad contact(210) is arranged between word lines. The direct contact(212) each other electrically connects first pad contacts and bit line. The second pad contact(214) is arranged between word lines and bit lines.
