  • Patent number: 11189717
    Abstract: A steep-slope (SS) field effect transistor (FET) including a FET having a source region and a drain region, and a threshold switching device in direct contact with the source region or the drain region of the FET. Fabricating the steep-slope (SS) field effect transistor (FET) includes fabricating an AlGaN/GaN metal-insulator-semiconductor high electron mobility transistor (MIS-HEMT) having a source region and a drain region, depositing a first electrode layer directly on the source region or the drain region, depositing a threshold switching layer directly on the first electrode layer, and depositing a second electrode layer directly on the threshold switching layer.

  • Publication number: 20140084472
    Abstract: The disclosure belongs to the field of manufacturing and interconnection of integrated circuits, and in particular relates to compound dielectric anti-copper-diffusion barrier layer for copper interconnection and a manufacturing method thereof The disclosure uses compound dielectric (oxide & metal) as the anti-copper-diffusion barrier layer. First, it can enhance the capable of metal for anti-copper-diffusion efficiently, and prevent the barrier layer for valid owing to oxidized and prolong the life of the barrier layer. Second, it can reduce the effective dielectric constant of the interconnection circuits and furthermore reduce the RC delay of the whole interconnection circuits. Besides, the alloy is firmly adhered to the copper, and the metal copper can be directly electroplated without growing a layer of seed crystal copper. The method is simple and feasible and is expected to be applied to manufacturing of the anti-copper-diffusion barrier layers for copper interconnections.

  • Patent number: 8455372
    Abstract: The present invention belongs to the technical field of semiconductor materials and specifically relates to a method for cleaning and passivizing gallium arsenide (GaAs) surface autologous oxide and depositing an Al2O3 dielectric. This method includes: use a new-type of sulfur passivant to react with the autologous oxide on the GaAs surface to clean it and generate a passive sulfide film to separate the GaAs from the outside environment, thus preventing the GaAs from oxidizing again; further cleaning the residuals such as autologous oxides and sulfides on the GaAs surface through the pretreatment reaction of the reaction source trimethyl aluminum (TMA) of the Al2O3 ALD with the GaAs surface, and then deposit high-quality Al2O3 dielectric through ALD as the gate dielectric which fully separates the GaAs from the outside environment. The present invention features a simple process and good effects, and can provide preconditions for manufacturing the GaAs devices.

  • Publication number: 20130078793
    Abstract: The present invention belongs to the technical field of integrated semiconductor circuits, and relates to a method for depositing a gate oxide and a gate electrode selectively. The present invention makes use of Octadecyltriethoxysilane's (ODTS') easy attachment to the Si—OH interface and difficult attachment to the Si—H interface, and selectively deposits the gate oxide and gate electrode materials, which avoids the unnecessary waste of materials and saves cost. Meanwhile, the present invention will transfer the etching of the gate oxide and gate electrode into the etching of SiO2 so as to reduce the difficulty of the etching process and increase the production efficiency.

  • Publication number: 20130078761
    Abstract: The present invention belongs to the technical field of low temperature atomic layer deposition technology, and specifically relates to a method for manufacturing a flexible transparent 1T1R storage unit. In the present invention, a fully transparent 1T1R storage unit is developed on a flexible substrate through a completely low-temperature process, including an oxide layer dielectric, a transparent electrode and a transparent substrate which are deposited together through a low-temperature process, thus realizing a fully transparent device capable of achieving the functions of nontransparent devices. The present invention can be applied to the manufacturing of flexible low-temperature storage units in the future, as well as changing the packaging and existing modes of devices, which will make foldable and bendable portable storage units possible.
