Methods for depositing a contact metal layer in contact structures of a semiconductor device are provided. In one embodiment, a method for depositing a contact metal layer for forming a contact structure in a semiconductor device is provided. The method comprises performing a cyclic metal deposition process to deposit a contact metal layer on a substrate and annealing the contact metal layer disposed on the substrate. The cyclic metal deposition process comprises exposing the substrate to a deposition precursor gas mixture to deposit a portion of the contact metal layer on the substrate, exposing the portion of the contact metal layer to a plasma treatment process, and repeating the exposing the substrate to a deposition precursor gas mixture and exposing the portion of the contact metal layer to a plasma treatment process until a predetermined thickness of the contact metal layer is achieved.

The antenna on hand held devices, such as the iPhone or iPad, can be subject to interference from other circuitry on the device. Such interference may come from high frequency switching of nearby display circuitry, such as de-multiplexors or other circuits. To address this issue, the switching rates may be slowed in certain circuits by adding resistance and/or capacitance, thus raising the RC time constant and slowing the switching times to reduce the high frequency components. Alternatively or in addition to, an EMI shield can be placed over some or all of the display driving circuitry to shield the antenna from high frequency interference.

Embodiments relate to halftone masks that can uniformly form the height of an underlying layer in two regions that are spaced apart from each other, a manufacturing method thereof, and a method for forming a film using the same. The halftone mask includes a first light blocking unit and a second light blocking unit, and a semi-transmitting unit that is disposed adjacent to the side of the second light blocking unit. The first and second light blocking units block light and are spaced apart from each other at a predetermined interval. The semi-transmitting unit is positioned at a side far from the first light blocking unit and reduces intensity of light. Sum of the second length of the second light blocking unit and the third length of the semi-transmitting unit is larger than the first length of the first blocking unit.

Embodiments of the invention generally provide methods for forming cobalt silicide. In one embodiment, a method for forming a cobalt silicide material includes exposing a substrate having a silicon-containing material to either a wet etch solution or a pre-clean plasma during a first step and then to a hydrogen plasma during a second step of a pre-clean process. The method further includes depositing a cobalt metal layer on the silicon-containing material by a CVD process, heating the substrate to form a first cobalt silicide layer comprising CoSi at the interface of the cobalt metal layer and the silicon-containing material during a first annealing process, removing any unreacted cobalt metal from the substrate during an etch process, and heating the substrate to form a second cobalt silicide layer comprising CoSi2 during a second annealing process.
