摘要： An improved method for making a semiconductor device is described. Initially, a structure is formed that includes first and second hard masking layers that cover a dielectric layer. A layer of photoresist is deposited and patterned to expose part of the second hard masking layer to define a via. That exposed part of the second hard masking layer is then etched. A second layer of photoresist is deposited and patterned to expose a second part of the second hard masking layer to define a trench. After etching the exposed second part of the second hard masking layer, a via and trench are etched into the dielectric layer, which are then filled with a conductive material.

摘要： 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.

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.

摘要翻译： 双镶嵌工艺，其中第一替代ILD由第一材料制成，第二替代ILD由第二材料制成。 在存在不同的蚀刻剂（例如有机聚合物和无机低k材料）的情况下，每种材料可以以比另一种更快的速度进行刻蚀。 这允许ILD彼此交替沉积而没有蚀刻剂停止层，从而降低电容。

摘要： Microelectronic structures embodying the present invention include a field effect transistor (FET) having highly conductive source/drain extensions. Formation of such highly conductive source/drain extensions includes forming a passivated recess which is back filled by epitaxial deposition of doped material to form the source/drain junctions. The recesses include a laterally extending region that underlies a portion of the gate structure. Such a lateral extension may underlie a sidewall spacer adjacent to the vertical sidewalls of the gate electrode, or may extend further into the channel portion of a FET such that the lateral recess underlies the gate electrode portion of the gate structure. In one embodiment the recess is back filled by an in-situ epitaxial deposition of a bilayer of oppositely doped material. In this way, a very abrupt junction is achieved that provides a relatively low resistance source/drain extension and further provides good off-state subthreshold leakage characteristics. Alternative embodiments can be implemented with a back filled recess of a single conductivity type.
