Semiconductor device
View Patent ↗Provided are embodiments of a semiconductor device having bit lines and bit bar lines. The bit lines and the bit bar lines are arranged in alternate succession across a substrate. At least two of proximate bit lines, bit line bars, power lines, and ground lines of the semiconductor device are formed on different layers, in order to reduce defects due to particles between lines, and increase yield.
1. A semiconductor device comprising:
a first dielectric on a substrate;
a first grouping of lines comprising bit lines on the first dielectric;
a first connecting pattern between the hit lines on the first dielectric;
a second dielectric on the first grouping of lines and the first connecting pattern;
a first via pattern in the second dielectric and connected to the first connecting pattern; and
a second grouping of lines comprising bit bar lines on the second dielectric,
wherein the first via pattern is connected to each bit bar line of the second grouping of lines,
wherein a bit line of the first grouping is in alternate succession with a bit bar line of the second grouping.
2. The semiconductor device according to claim 1 , wherein the first grouping of lines comprises bit lines only, and the second grouping of lines comprises bit bar lines only.
3. The semiconductor device according to claim 2 , further comprising a first contact pattern in the first dielectric connected to each bit line of the first grouping of lines.
4. The semiconductor device according to claim 2 , further comprising a second contact pattern in the first dielectric and connected to the first connecting pattern.
