    摘要: A semiconductor arrangement and method of formation are provided. The semiconductor arrangement comprises a conductive contact in contact with a substantially planar first top surface of a first active area, the contact between and in contact with a first alignment spacer and a second alignment spacer both having substantially vertical outer surfaces. The contact formed between the first alignment spacer and the second alignment spacer has a more desired contact shape then a contact formed between alignment spacers that do not have substantially vertical outer surfaces. The substantially planar surface of the first active area is indicative of a substantially undamaged structure of the first active area as compared to an active area that is not substantially planar. The substantially undamaged first active area has a greater contact area for the contact and a lower contact resistance as compared to a damaged first active area.

    摘要: A semiconductor arrangement and method of formation are provided. The semiconductor arrangement includes an interconnect which includes an interconnect metal plug surrounded by a second metal layer. The interconnect is adjacent a sidewall of a dielectric, such that an air gap is between the interconnect and the sidewall of the dielectric. A protective barrier is over the interconnect and the air gap, and is over and in direct physical contact with a top surface of the dielectric. The interconnect metal plug surrounded by the second metal layer is less susceptible to damage than an interconnect metal plug that is not surrounded by a second metal layer. The protective barrier in direct physical contact with the dielectric reduces parasitic capacitance, which reduces an RC delay of the semiconductor arrangement, as compared to a semiconductor arrangement that does not have a protective barrier in direct physical contact with a dielectric.
