    摘要: An isolation trench (60) may comprise a trench (20) formed in a semiconductor layer (12). A barrier layer (22) may be formed along the trench (20). A protective liner (50) may be formed over the barrier layer (22). The protective liner (50) may comprise a chemically deposited oxide. A high density layer of insulation material (55) may be formed in the trench (20) over the protective liner (50).

    摘要: Air-bridges are formed at controlled lateral separations using the extremely high HF etch rate of a gap-fill spin-on-glass such as uncured hydrogen silsequioxane (HSQ) in combination with other dielectrics having a much slower etch rate in HF. The advantages of an air-bridge system with controlled lateral separations include providing an interconnect isolation dielectric which meets all requirements for sub-0.5 micron technologies and providing a device with reduced reliability problems.

    摘要: A process for forming controlled airgaps (22) between metal lines (16). A two-step high density plasma (HDP) chemical vapor deposition (CVD) process is used to form the silicon dioxide dielectric layer (20) with the controlled airgaps (22). The first step involves a high gas flow and low substrate bias conditions to deposit silicon dioxide with a high deposition to sputter etch ratio. The second step uses a low gas flow and high substrate bias condition to increase the sputter component of the deposition.

    摘要: A structure and method to further reduce the dielectric constant (capacitance) of high density plasma chemical vapor deposited silicon dioxide (SiO2 12). The dielectric constant of voids (i.e. air pockets) is close to k=1.0, and therefore the microvoids reduce the effective dielectric constant of the silicon dioxide 12. Use of HDPCVD conditions avoids residual hydrogen, which would degrade the dielectric constant.
