Assemblies having shield lines of an upper wiring level electrically coupled with shield lines of a lower wiring level

An assembly, comprising:

• a first wiring level comprising a first shield line and a first signal line immediately adjacent the first shield line;
• a second wiring level below the first wiring level and comprising a second shield line and a second signal line immediately adjacent the second shield line;
• the first shield line having a first portion extending in a first direction, a second portion extending in a second direction, and a third portion extending in the first direction;
• the second portion interconnecting an end of the first portion to an end of the third portion;
• the first signal line having fourth, fifth and sixth portions that are substantially parallel to the third, second and first portions, respectively, of the first shield line;
• the second shield line including seventh and eighth portions that are under and substantially vertically aligned with the third portion of the first shield line and the fourth portion of the first signal line, respectively;
• the seventh portion extending continuously to under the sixth portion of the first signal line in the first direction;
• and
• a vertical interconnect which electrically connects the third portion of the first shield line to the seventh portion of the second shield line.

An assembly, comprising:

• a first wiring level comprising first shield lines in alternating arrangement with first signal lines;
• each of the first shield lines extending primarily along a first direction, and extending along two first paths which are laterally offset relative to one another;
• a second wiring level below the first wiring level and comprising second shield lines in alternating arrangement with second signal lines;
• each of the second shield lines extending primarily along the first direction and extending along two second paths which are laterally offset relative to one another;
• a mesh structure comprising the first shield lines electrically coupled with the second shield lines;
• the first shield lines being primarily laterally offset from the second shield lines except that each of the first paths of each of the first shield lines has overlap regions where portions of the first shield lines vertically overlap portions the second shield lines;
• vertical interconnects being within said overlap regions to connect the first shield lines with the second shield lines;
• and
• one of the first paths of an individual first shield line having an overlap region which is over one of the second paths of an individual second shield line;
• the other of the first paths of the individual first shield line having another overlap region which is over a second path of another individual second shield line.

An assembly, comprising:

• a first wiring level comprising a first shield line and a signal line adjacent the first shield line;
• the first shield line having a first segment extending along a first direction, a second segment extending along the first direction and laterally offset from the first segment, and a first linking segment interconnecting the first and second segments to one another;
• the signal line having third and fourth segments and a second linking segment that are substantially parallel to the first and second segments and the first linking segment, respectively, of the first shield line;
• a second wiring level below the first wiring level and comprising a second shield line including fifth segment extending along the first direction;
• the fifth segment including first and second portions that are substantially vertically aligned with the first segment of the first shield line and the fourth segment of the signal line, respectively;
• and
• a vertical interconnect connecting electrically the first segment of the first shield line with the first portion of the fifth segment of the second shield line.
