具有平行互补鳍片场效应晶体管对的集成电路
摘要：
公开了一种用于集成电路结构的方法和结构，该集成电路结构利用了互补鳍片型场效应晶体管(FinFET)。本发明具有包括第一鳍片(100)的第一类型FinFET，以及包括平行于第一鳍片(100)延伸的第二鳍片(102)的第二类型FinFET。本发明还具有位于第一类型FinFET和第二类型FinFET的源极/漏极区域(130)之间的绝缘鳍片。绝缘鳍片具有与第一鳍片(100)和第二鳍片(102)基本相同的宽度尺寸，以便第一类型FinFET和第二类型FinFET之间的间隔大约等于一个鳍片的宽度。本发明还具有在第一类型FinFET和第二类型FinFET的沟道区域上形成的公共栅极(106)。栅极(106)包括与第一类型FinFET相邻的第一杂质掺杂区域和与第二类型FinFET相邻的第二杂质掺杂区域。第一杂质掺杂区域和第二杂质掺杂区域之间的差别给所述栅极提供与第一类型FinFET和第二类型FinFET之间的差别相关的不同的功函数。第一鳍片(100)和第二鳍片(102)具有大约相同的宽度。
摘要（英）：

A method and structure for an integrated circuit structure that utilizes complementary fin-type field effect transistors (FinFETs) is disclosed. The invention has a first-type of FinFET which includes a first fin, and a second-type of FinFET which includes a second fin running parallel to the first fin. The invention also has an insulator fin positioned between the source/drain regions of the first first-type of FinFET and the second-type of FinFET. The insulator fin has approximately the same width dimensions as the first fin and the second fin, such that the spacing between the first-type of FinFET and the second-type of FinFET is approximately equal to the width of one fin. The invention also has a common gate formed over channel regions of the first-type of FinFET and the second-type of FinFET. The gate includes a first impurity doping region adjacent the first-type of FinFET and a second impurity doping region adjacent the second-type of FinFET. The differences between the first impurity doping region and the second impurity doping region provide the gate with different work functions related to differences between the first-type of FinFET and the second-type of FinFET. The first fin and the second fin have approximately the same width.
