    Abstract: Methods of forming a high dielectric constant dielectric layer are disclosed including providing a process chamber including a holder for supporting a substrate, introducing a first gas comprising a high dielectric constant (Hi-K) dielectric precursor and an oxygen (O2) oxidant into the process chamber to form a first portion of the high dielectric constant dielectric layer on the substrate, and switching from a flow of the first gas to a flow of a second gas comprising the Hi-K dielectric precursor and an ozone (O3) oxidant to form a second portion of the high dielectric constant dielectric layer on the first portion. In an alternative embodiment, another portion can be formed on the second portion using the oxygen oxidant. The invention increases throughput by at least 20% without reliability or leakage degradation and without the need for additional equipment.

    Abstract: A method for forming a transmission line structure for a semiconductor device includes forming an interlevel dielectric layer over a first metallization level, removing a portion of the interlevel dielectric layer and forming a sacrificial material within one or more voids created by the removal of the portion of the interlevel dielectric layer. A signal transmission line is formed in a second metallization level formed over the interlevel dielectric layer, the signal transmission line being disposed over the sacrificial material. A portion of dielectric material included within the second metallization level is removed so as to expose the sacrificial material, wherein a portion of the sacrificial material is exposed through a plurality of access holes formed through the signal transmission line. The sacrificial material is removed so as to create an air gap beneath the signal transmission line.

    Abstract: A polysilicon containing resistor includes: (1) a p dopant selected from the group consisting of boron and boron difluoride; and (2) an n dopant selected from the group consisting of arsenic and phosphorus. Each of the p dopant and the n dopant has a dopant concentration from about 1e18 to about 1e21 dopant atoms per cubic centimeter. A method for forming the polysilicon resistor uses corresponding implant doses from about 1e14 to about 1e16 dopant ions per square centimeter. The p dopant and the n dopant may be provided simultaneously or sequentially. The method provides certain polysilicon resistors with a sheet resistance percentage standard deviation of less than about 1.5%, for a polysilicon resistor having a sheet resistance from about 100 to about 5000 ohms per square.
