  • Patent number: 10586860
    Abstract: In conjunction with a replacement metal gate (RMG) process for forming a fin field effect transistor (FinFET), gate isolation methods and associated structures leverage the formation of distinct narrow and wide gate cut regions in a sacrificial gate. The formation of a narrow gate cut between closely-spaced fins can decrease the extent of etch damage to interlayer dielectric layers located adjacent to the narrow gate cut by delaying the deposition of such dielectric layers until after formation of the narrow gate cut opening. The methods and resulting structures also decrease the propensity for short circuits between later-formed, adjacent gates.

  • Patent number: 10461199
    Abstract: The present disclosure discloses a manufacturing method of a thin film transistor, including: forming a gate layer on a substrate; forming a gate insulating layer on the gate layer and the substrate; forming an active layer on the gate insulating layer; and simultaneously forming a source and a drain formed on the active layer by a combination of a chemical plating method and a lift-off method. In the present disclosure, the chemical plating method is combined with the lift-off method, so that the wet-etching method is not used for forming the source and the drain, and thus the IGZO at the channel is not required to be protected by the etching-stop-layer. Therefore, while simplifying the production process, but also can reduce costs.
