Abstract:
A co-sputter technique is used to deposit In—Ga—Zn—O films using PVD. The films are deposited in an atmosphere including both oxygen and argon. A heater setpoint of about 300 C results in a substrate temperature of about 165 C. One target includes an alloy of In, Ga, Zn, and O with an atomic ratio of In:Ga:Zn of about 1:1:1. The second target includes a compound of zinc oxide. The third target includes a compound of indium oxide. The films exhibit the c-axis aligned crystalline (CAAC) phase in an as-deposited state, when deposited at room temperature, without the need of a subsequent anneal treatment.

Abstract:
Contacts for semiconductor devices and methods of making thereof are disclosed. A method comprises forming a first layer on a semiconductor, the first layer comprising one or more metals; forming a second layer on the first layer, the second layer comprising the one or more metals, nitrogen and oxygen; and heating the first and second layer such that oxygen migrates from the second layer into the first layer and the first layer comprises a sub-stoichiometric metal oxide after heating. Exemplary embodiments use transition metals such as Ti in the first layer. After heating there is a sub-stoichiometric oxide layer of about 2.5 nm thickness between a metal nitride conductor and the semiconductor. The specific contact resistivity is less than about 7×10−9 Ω·cm2.
Abstract:
Methods for making conducting stacks includes forming a doped or alloyed silver layer sandwiched between two layers of transparent conductive oxide such as indium tin oxide (ITO). The doped silver or silver alloy layer can be thin, such as between 1.5 to 20 nm and thus can be transparent. The doped silver or silver alloy can provide improved ductility property, allowing the conductive stack to be bendable. The transparent conductive oxide layers can also be thin, allowing the conductive stack to have an improved ductility property.
Abstract:
A combinatorial processing system having modular dispense heads is provided. The modular dispense heads are disposed on a rail system enabling an adjustable pitch of the modular dispense heads for the combinatorial processing. The modular dispense heads are configured so that sections of the modular dispense heads are detachable in order to accommodate various processes through a first section without having to completely disconnect and re-connect facilities to a second section.
Abstract:
A bi-layer seed layer can exhibit good seed property for an infrared reflective layer, together with improved thermal stability. The bi-layer seed layer can include a thin zinc oxide layer having a desired crystallographic orientation for a silver infrared reflective layer disposed on a bottom layer having a desired thermal stability. The thermal stable layer can include aluminum, magnesium, or bismuth doped tin oxide (AlSnO, MgSnO, or BiSnO), which can have better thermal stability than zinc oxide but poorer lattice matching for serving as a seed layer template for silver (111).

A method for reducing the leakage current in DRAM MIM capacitors comprises forming a multi-layer dielectric stack from an amorphous highly doped material, an amorphous high band gap material, and a lightly-doped or non-doped material. The highly doped material will remain amorphous (
Abstract:
Conducting materials having narrow impurity conduction bands can reduce the number of high energy excitations, and can be prepared by a sequence of plasma treatments. For example, a dielectric layer can be exposed to a first plasma ambient to form vacancy sites, and the vacancy-formed dielectric layer can be subsequently exposed to a second plasma ambient to fill the vacancy sites with substitutional impurities.

A method for reducing the leakage current in DRAM Metal-Insulator-Metal capacitors includes forming a flash layer between the dielectric layer and the first electrode layer. A method for reducing the leakage current in DRAM Metal-Insulator-Metal capacitors includes forming a capping layer between the dielectric layer and the second electrode layer. The flash layer and the capping layer can be formed using an atomic layer deposition (ALD) technique. The precursor materials used for forming the flash layer and the capping layer are selected such they include at least one metal-oxygen bond. Additionally, the precursor materials are selected to also include “bulky” ligands.
