    • A manufacturing method for a resistor integrated with a transistor having metal gate includes providing a substrate having a transistor, a transitional structure, and a dielectric layer covering the transistor and the transitional structure formed thereon, forming a recess in between two opposite polysilicon end portions in the transitional structure, forming a U-shaped resistance modulating layer and an insulating layer filling the recess, removing a dummy gate of the transistor and the polysilicon end portions of the transitional structure to form a gate trench and two terminal trenches respectively in the transistor and the transitional structure, and forming a metal gate in the gate trench and conductive terminals in the terminal trenches simultaneously.
    • 一种与具有金属栅极的晶体管集成的电阻器的制造方法,包括:提供具有晶体管的基板,过渡结构以及覆盖晶体管的过渡结构的介电层和在其上形成的过渡结构,在两个相对的多晶硅端部之间形成凹部 过渡结构,形成U形电阻调制层和填充凹槽的绝缘层,去除晶体管的虚拟栅极和过渡结构的多晶硅端部分别在晶体管中形成栅极沟槽和两个端子沟槽,以及 过渡结构,并且在栅极沟槽中形成金属栅极和端子沟槽中的导电端子。
