摘要:
A dual-damascene process where first alternate ILDs are made of a first material and second alternate ILDs are made of a second material. Each material is etchable at a faster rate than the other in the presence of different etchant such as for an organic polymer and an inorganic low k material. This allows the ILDs to be deposited alternately on one another without an etchant stop layer thereby reducing capacitance.

A method and apparatus are provided an interconnect cladding layer. In one embodiment, a first sacrificial layer is deposited over a substrate and patterned. In the vias created during the patterning operation, a conductive material is placed to create conductive interconnects. After planarizing the conductive material, the sacrificial layer is removed leaving the interconnect exposed. A cladding layer is then deposited over the conductive material.

The invention relates to a microelectronic device and a structure therein that includes a diffusion barrier layer having a first thickness and a first dielectric constant. An etch stop layer is disposed above and on the diffusion barrier layer. The etch stop layer has a second thickness and a second dielectric constant.

In one aspect, an apparatus may include a metal gate of a transistor. An etch stop layer may be selectively formed over the metal gate. The etch stop layer may include a metal compound. An insulating layer may be over the etch stop layer. A conductive structure may be included through the insulating layer to the metal gate. Methods of making such transistors are also disclosed.

In one embodiment, the present invention includes introducing a precursor containing hydrocarbon substituents and optionally a second conventional or hydrocarbon-containing precursor into a vapor deposition apparatus; and forming a dielectric layer having the hydrocarbon substituents on a substrate within the vapor deposition apparatus from the precursor(s). In certain embodiments, at least a portion of the hydrocarbon substituents may be later removed from the dielectric layer to reduce density thereof.

摘要:
The invention forms a graded modified layer in a substrate by exposing the substrate to hydrogen plasma. Methyl groups may be removed from carbon doped oxide in the substrate by the hydrogen plasma treatment. This may result in a stronger interface between the substrate and an etch stop layer on the substrate.
摘要:
A method for operating a multi-station processing chamber is described. A wafer is loaded onto the first station then indexed to the second station prior to processing. The indexing causes the wafer to be well-seated on it spindle before being processed. This prevents an improperly seated wafer from being processed at the first station.
