Patent ID: 7687342

Claim:
A method of manufacturing a memory device, the method comprising: providing a substrate; defining at least one active area within the substrate, said active area comprising a source and two drains, the source and at least one of the drains forming a line along which a first axis is defined; defining at least one pair of word lines within the substrate by a pitch-doubling technique, the word lines of the pair being parallel one another over the active area along a word line axis; and defining at least two digit lines above the substrate, at least a portion of one of the at least two digit lines extending above the source and defining a second axis that forms an acute angle with the first axis, the second axis running perpendicular to the word line axis, the at least two digit lines having a pitch of between 2.75 and 3.25 times a minimum resolution (F) of a photolithographic technique used to form the memory device.
