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.

Abstract: A polysilicon layer is formed over a substrate. The polysilicon layer is etched to form a dummy gate electrode having a top portion with a first lateral dimension and a bottom portion with a second lateral dimension. The first lateral dimension is greater than, or equal to, the second lateral dimension. The dummy gate electrode is replaced with a metal gate electrode.

Abstract: A device includes a substrate, a first conductive layer on the substrate, a first conductive via, and further conductive layers and conductive vias between the first conductive via and the substrate. The first conductive via is between the substrate and the first conductive layer, and is electrically connected to the first conductive layer. The first conductive via extends through at least two dielectric layers, and has thickness greater than about 8 kilo-Angstroms. An inductor having high quality factor is formed in the first conductive layer and also includes the first conductive via.

Abstract: The present disclosure provides a multifunction chamber having a multifunctional shutter disk. The shutter disk includes a lamp device, a DC/RF power device, and a gas line on one surface of the shutter disk. With this configuration, simplifying the chamber type is possible as the various specific, dedicated chambers such as a degas chamber, a pre-clean chamber, a CVD/PVD chamber are not required. By using the multifunctional shutter disk, the degassing function and the pre-cleaning function are provided within a single chamber. Accordingly, a separate degas chamber and a pre-clean chamber are no longer required and the overall transfer time between chambers is reduced or eliminated.

Abstract: A method of manufacturing a semiconductor device includes forming a photoresist layer over a substrate, including combining a first precursor and a second precursor in a vapor state to form a photoresist material, and depositing the photoresist material over the substrate. A protective layer is formed over the photoresist layer. The photoresist layer is selectively exposed to actinic radiation through the protective layer to form a latent pattern in the photoresist layer. The protective layer is removed, and the latent pattern is developed by applying a developer to the selectively exposed photoresist layer to form a pattern.

Abstract: A method of manufacturing semiconductor device includes forming a multilayer photoresist structure including a metal-containing photoresist over a substrate. The multilayer photoresist structure includes two or more metal-containing photoresist layers having different physical parameters. The metal-containing photoresist is a reaction product of a first precursor and a second precursor, and each layer of the multilayer photoresist structure is formed using different photoresist layer formation parameters. The different photoresist layer formation parameters are one or more selected from the group consisting of the first precursor, an amount of the first precursor, the second precursor, an amount of the second precursor, a length of time each photoresist layer formation operation, and heating conditions of the photoresist layers. The multilayer photoresist structure is selectively exposed to actinic radiation to form a latent pattern, and the latent pattern is developed by applying developer to the selectively exposed multilayer photoresist structure to form the pattern.

Abstract: The treatment system provides a feature that may reduce cost of the electrochemical plating process by reusing the virgin makeup solution in the spent electrochemical plating bath. The treatment system provides a rotating filter shaft which receives the spent electrochemical plating bath and captures the additives and by-products created by the additives during the electrochemical plating process. To capture the additives and the by-products, the rotating filter shaft includes one or more types of membranes. Materials such as semi-permeable membrane are used to capture the used additives and by-products in the spent electrochemical plating bath. The treatment system may be equipped with an electrochemical sensor to monitor a level of additives in the filtered electrochemical plating bath.
