Abstract
An integrated circuit including a signal line layout is disclosed. A signal line layout may include a number of signal lines configured for conveying a number of signals. The signal line layout may further include a number of shield lines. Each signal line of the number of signal lines may be positioned adjacent a first shield line and a second shield line of the number of the shield lines. Further, first shield line may extend a length of an adjacent signal line and the second shield line may extend less than a length of the adjacent signal line. An electronic system including circuitry having one or more signal line layouts, and methods of forming signal line layout are also described.
Claims21
An integrated circuit, comprising:
- a signal line layout, comprising:
- a number of signal lines configured for conveying a number of signals;
- and
- a number of shield lines, wherein each signal line of the number of signal lines is positioned between a first shield line and a second shield line of the number of shield lines, the first shield line extending a length of an adjacent signal line and the second shield line extending less than a length of the adjacent signal line.
A method of forming a signal line layout of an integrated circuit, comprising:
- forming a first signal line for conveying a signal;
- forming a first shield line adjacent a first side of the first signal line and extending at least a length of the first signal line;
- forming a second shield line adjacent a portion of a second, opposite side of the first signal line and extending less than the length of the first shield line;
- forming a second signal line including a first side adjacent at least a portion of the second shield line;
- and
- forming a third shield line adjacent a second, opposite side of the second signal line and extending at least a length of the second signal line.
An electronic system comprising:
- at least one input device;
- at least one output device;
- at least one processor device operably coupled to the input device and the output device;
- and
- at least one semiconductor device operably coupled to the at least one processor device and including circuitry, the circuitry comprising:
- a first signal line having a first length;
- a first shield line positioned adjacent a first side of the first signal line and having a second length greater than or substantially equal to the first length of the first signal line;
- a second shield line positioned adjacent a second side of the first signal line and having a third length less than the second length of the first shield line, the second side of the first signal line opposite the first side of the first signal line;
- and
- a second signal line, wherein a first portion of the second signal line is positioned adjacent the second shield line and a second portion of the second signal line is positioned adjacent the second, opposite side of the first signal line.
A method of forming a signal line layout of an integrated circuit, comprising:
- forming a number of signal lines for conveying signals, respectively;
- and
- forming a number of shield lines such that each of the number of signal lines is partially positioned in a shielded region between a full shield and a partial shield of the number of shield lines, the shielded region being equal among the number of shield lines.
