Patent number: 7875550Abstract: Disclosed are embodiments of a semiconductor structure with a partially selfaligned contact in lower portion of the contact is enlarged to reduce resistance without impacting device yield. Additionally, the structure optionally incorporates a thick middle-of-the-line (MOL) nitride stress film to enhance carrier mobility. Embodiments of the method of forming the structure comprise forming a sacrificial section in the intended location of the contact. This section is patterned so that it is self-aligned to the gate electrodes and only occupies space that is intended for the future contact.

Conventional contact lithography is used to etch a contact hole through the dielectric layer(s) to the sacrificial section. The sacrificial section is then selectively removed to form a cavity and the contact is formed in the cavity and contact hole.Type: GrantFiled: April 28, 2008Date of Patent: January 25, 2011Assignee: International Business Machines CorporationInventors: Gregory Costrini, David M.
