Abstract
In operation, a standard cell library having diode place-holders (16) associated with standard cell inputs (12) is used to design a standard cell-based semiconductor device. Each standard cell in the standard cell-based semiconductor device is analyzed to determine if its standard cell inputs (12) will be connected to a conductive element (18) during processing that can accumulate a charge. When a conductive element (18) that can accumulate charge is identified, the diode place-holder (16) associated with its standard cell input (12) is replaced with a diode (16).
Claims2
A method of manufacturing a semiconductor device comprising:
- receiving a semiconductor device design file comprising a first standard cell for performing a logical function, the first standard cell having an input gate and an interconnect layer;
- determining, based on the semiconductor device design file, if the input gate of the first standard cell is coupled to an interconnect layer object meeting a size requirement, wherein the step of determining is true when the interconnect layer object meets the size requirement;
- replacing the first standard cell with a second standard cell for performing the logical function when the step of determining is true, the second standard cell having an input gate, an interconnect layer, and a diode coupled to the input gate;
- and
- manufacturing the semiconductor device based on the semiconductor device design file.
