ground line structure 203 and each of the metal1 word line structures 201 and the metal1 ground line structures 203 has a tip edge that oppositely faces a side edge of a metal1 bitline structure 207 which is formed as a vertical line side edges of the metal1 word line structure 201 and the metal1 ground line structure 203 may be 1 4 to 1 8 times longer than tip edges of the metal1 word line structure 201 and the metal1 ground line structure 203 respectively as a result of the double patterning the spacing between particular metal layer structures of different colors may be reduced for example the tip to side space between a metal1 word line structure 201 and a metal1 bit line structure 207 and the tip to side space between a metal1 ground line structure 203 and a metal1 bit line structure 207 of bit cell 200 are significantly narrower than their respective space counterparts in a typical bit cell moreover because of the shape and the arrangement of the components of bit cell 200 the spacing between particular metal layer structures of the same color may also be decreased for example the side to side space between a metal1 word line structure 201 and a metal1 ground line structure 203 of bit cell 200 are significantly narrower than the tip to.
