    Abstract: A semiconductor device includes a substrate including a first area and a second area, and first and second transistors formed in the first area and the second area, respectively. The first transistor includes a first gate insulating layer on the substrate, a first TiN layer on the first gate insulating layer contacting the first gate insulating layer, and a first filling layer on the first TiN layer. The second transistor includes a second gate insulating layer on the substrate, a second TiN layer on the second gate insulating layer contacting the second gate insulating layer, and a second filling layer on the second TiN layer. A threshold voltage of the first transistor is less than that of the second transistor, the second gate insulating layer does not comprise lanthanum, and an oxygen content of a portion of the first TiN layer is greater than that of the second TiN layer.

    Abstract: Use of a replacement metal gate (RMG) process provides an opportunity to create precision polysilicon resistors alongside metal gate transistors. During formation of a sacrificial polysilicon gate, the precision polysilicon resistor can also be formed from the same polysilicon film. The polysilicon resistor can be slightly recessed so that a protective insulating layer can cover the resistor during subsequent replacement of the sacrificial gate with a metal gate. The final structure of the precision polysilicon resistor fabricated using such a process is more compact and less complex than existing structures that provide metal resistors for integrated circuits having metal gate transistors. Furthermore, the precision polysilicon resistor can be freely tuned to have a desired sheet resistance by either implanting the polysilicon film with dopants, adjusting the polysilicon film thickness, or both.

    Abstract translation: 使用替代金属栅极(RMG)工艺提供了在金属栅极晶体管旁边创建精密多晶硅电阻的机会。 在牺牲多晶硅栅极的形成期间,也可以由相同的多晶硅膜形成精密多晶硅电阻器。 多晶硅电阻器可以稍微凹进,使得在随后用金属栅极替换牺牲栅极时,保护绝缘层可以覆盖电阻器。 使用这种工艺制造的精密多晶硅电阻器的最终结构比为具有金属栅极晶体管的集成电路提供金属电阻器的现有结构更紧凑和更不复杂。 此外,通过用掺杂剂注入多晶硅膜,调节多晶硅膜厚度或两者,可以将精密多晶硅电阻器自由地调谐为具有所需的薄层电阻。
