摘要： An integrated circuit biases the substrate and well using voltages other than those used for power and ground. Tap cells inside the standard cell circuits are removed. New tap cells used to bias the substrate and well reside outside the standard cell circuits. The location of the new voltage power rails is designated prior to placement of the tap cells in the integrated circuit. The tap cells are then strategically placed near the power rails such that metal connections are minimized. Circuit density is thus not adversely impacted by the addition of the new power rails. Transistors are also placed inside the tap cells to address electrostatic discharge issues during fabrication.

摘要翻译： 集成电路利用电源和接地以外的电压来偏置衬底和阱。 拆除标准电池电路内的电池。 用于偏置衬底的新的抽头电池很好地驻留在标准电池电路之外。 在将分接电池放置在集成电路中之前，指定新电压电源轨的位置。 然后将龙头电池策略性地放置在电源轨附近，使金属连接最小化。 因此，电路密度不会因添加新的电源轨而受到不利影响。 晶体管也放置在抽头单元内，以解决制造过程中的静电放电问题。
