An interconnect structure and method of making the same are provided. The interconnect structure includes a dielectric layer having a patterned opening, a metal feature disposed in the patterned opening, and a dielectric cap overlying the metal feature. The dielectric cap has an internal tensile stress, the stress helping to avoid electromigration from occurring in a direction away from the metal line, especially when the metal line has tensile stress.

A method of processing wafers within a high density plasma chemical vapor deposition chamber comprises setting a plasma charge level within the chamber at a zero power level and, while the plasma charge level within the chamber is at the zero power level, moving a wafer into the chamber. Then, the method sets the plasma charge level to a second power level higher than zero after the wafer is moved into the chamber and performs a chemical vapor deposition process on the wafer within the chamber. After performing the chemical vapor deposition process, the method moves the wafer to a non-plasma region within the chamber. Then, after moving the wafer to the non-plasma region within the chamber, the method again sets the plasma charge level within the chamber at the zero power level. Next, after setting the plasma charge level within the chamber at the zero power level, the method opens the door of the chamber and, while the plasma charge level within the chamber is at the zero power level, the method removes the wafer from the chamber through the door of the chamber.

An HDP process for high aspect ratio gap filling comprises contacting a semiconductor substrate with an oxide precursor under high density plasma conditions at a first pressure less than about 10 millitorr, wherein said gaps are partially filled with oxide; and further contacting the substrate with an oxide precursor under high density plasma conditions at a second pressure greater than about 10 millitorr, wherein said gaps are further filled with oxide.

A stress nitride structure is formed on an integrated circuit field effect transistor by high density plasma (HDP) depositing a first stress nitride layer on the integrated circuit field effect transistor and then plasma enhanced chemical vapor depositing (PECVD) a second stress nitride layer on the first stress nitride layer. The first stress nitride layer is non-conformal and the second stress nitride layer is conformal. Related structures also are described.

A CMOS structure and methods for fabricating the CMOS structure provide that a first stressed layer located over a first transistor and a second stressed layer located over a second transistor abut but do not overlap. Such an abutment absent overlap provides for enhanced manufacturing flexibility when forming a contact to a silicide layer upon a source/drain region within one of the first transistor and the second transistor.

摘要:
A dielectric cap and related methods are disclosed. In one embodiment, the dielectric cap includes a dielectric material having an optical band gap (e.g. greater than about 3.0 electron-Volts) to substantially block ultraviolet radiation during a curing treatment, and including nitrogen with electron donor, double bond electrons. The dielectric cap exhibits a high modulus and is stable under post ULK UV curing treatments for, for example: copper low k back-end-of-line (BEOL) nanoelectronic devices, leading to less film and device cracking and improved reliability,
