    Abstract: Methods for tuning threshold voltages of fin-like field effect transistor devices are disclosed herein. An exemplary method includes forming a first opening in a first gate structure and a second opening in a second gate structure. The first gate structure is disposed over a first fin structure, and the second gate structure is disposed over a second fin structure. The method further includes filling the first opening and the second opening by forming a gate dielectric layer, forming a threshold voltage tuning layer over the gate dielectric layer, etching back the threshold voltage tuning layer in the second opening, forming a work function layer over the threshold voltage tuning layer, and forming a metal fill layer over the work function layer. The threshold voltage tuning layer includes tantalum and nitrogen. The etching back uses a tungsten-chloride containing precursor.

    Abstract: A method for fabricating a semiconductor structure is provided, including: providing a solid precursor having a first average particle size; solving the solid precursor in an organic solvent into an intermediate; recrystallizing the intermediate to form solid granules, wherein the solid granules has a second average particle size larger than the first average particle size; vaporizing the solid granules to form a film-forming gas; and depositing the film-forming gas on a substrate to form a resistance film. A method for modifying a resistance film source in a semiconductor fabrication and a solid precursor delivery system are also provided. The method for fabricating a semiconductor structure in the present disclosure can remove small particles or ultra-small particles from solid precursor, and does not need extra time to dump cracked solid precursor.

    Abstract: A apparatus includes a susceptor and a non-reactive gas source. The susceptor has through holes and a wafer support surface. Each through hole includes a lift pin and a lift pin head. The lift pin has a vertical degree of motion in the through hole to lift up or place a wafer on the susceptor. The lift pin head has at least one flow channel structure running from its first surface at least partially exposed to a bottom side of the susceptor through its second surface exposed to a top side of the susceptor wherein the lift pin. The non-reactive gas source is configured to flow a gas to a backside of the wafer through the flow channel structure through the bottom side of the susceptor.

    Abstract: An overhead transport vehicle is described for association with an Automated Material Handling System (AMHS). The overhead transport vehicle provides features to the AMHS by which the AMHS is able to reduce a number of manual urgent lot rescues by the fab operator when a logistic algorithm controlling traffic in the AMHS is unable to transport the front opening unified pods (FOUP) from one tool to the subsequent tool in the sequence of the process steps within the q-time due to unexpected problems. An indicator on the overhead transport vehicle which helps the fab operator with spotting a lot in trouble is described. A backup power source on the overhead transport vehicle used in case of a main power failure is also described.
