Abstract

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.
