Abstract:
A heater assembly with enhanced cooling pursuant to various embodiments described herein makes use of fluidic flow in the insulation or in the space used for insulation. By creating a natural convection or forced convection flow, the heater cools down faster, it can operate at lower temperatures and/or higher temperature precision, and it can improve temperature controllability by generating higher heat loss rates.
Abstract:
The invention relates to a semiconductor device including an oxide semiconductor layer, a gate electrode overlapping with a channel formation region of the oxide semiconductor layer, and a source electrode or a drain electrode overlapping with a first region of the oxide semiconductor layer, and a second region between the channel formation region and the first region. An upper layer of the second region includes a microvoid. The microvoid is formed by adding nitrogen to the upper layer of the second region. Thus, upper layer of the second region contains lager amount of nitrogen than a lower layer of the second region.
Abstract:
It is an object to provide a highly reliable semiconductor device, a semiconductor device with low power consumption, a semiconductor device with high productivity, and a method for manufacturing such a semiconductor device. Impurities left remaining in an oxide semiconductor layer are removed without generating oxygen deficiency, and the oxide semiconductor layer is purified to have an extremely high purity. Specifically, after oxygen is added to the oxide semiconductor layer, heat treatment is performed on the oxide semiconductor layer to remove the impurities. In order to add oxygen, it is preferable to use a method in which oxygen having high energy is added by an ion implantation method, an ion doping method, or the like.
Abstract:
Methods and devices for preventing channeling of dopants during ion implantation are provided. The method includes providing a semiconductor substrate and depositing a sacrificial scattering layer (205) over at least a portion a surface of the substrate, wherein the sacrificial scattering layer includes an amorphous material. The method further includes ion implanting a dopant (250) through the sacrificial scattering layer to within a depth profile (220) in the substrate. Subsequently, the sacrificial scattering layer can be removed such that erosion of the substrate surface is less than one percent of a thickness of the sacrificial scattering layer.
Abstract:
A method of preventing toxic gas formation after an implantation process is disclosed. Certain dopants, when implanted into films disposed on a substrate, may react when exposed to moisture to form a toxic gas and/or a flammable gas. By in-situ exposing the doped film to an oxygen containing compound, dopant that is shallowly implanted into the layer stack reacts to form a dopant oxide, thereby reducing potential toxic gas and/or flammable gas formation. Alternatively, a capping layer may be formed in-situ over the implanted film to reduce the potential generation of toxic gas and/or flammable gas.

The method maintains the first substrate including the first plurality of tiles in a vacuum. The method includes transferring the first substrate including the first plurality of tiles from the inlet port onto the movable track member. The first plurality of tiles are subjected to a scanning implant process. The method also includes maintaining a second substrate including a second plurality of tiles in the vacuum. The method includes transferring the second substrate including a second plurality of tiles from the inlet port onto the movable track member. The method includes subjecting the second plurality of tiles to an implant process using the scanning implant process.
Abstract:
A method of manufacturing a semiconductor device includes providing semiconductor substrate having trenches and mesas. At least one mesa has first and second sidewalls. The method includes angularly implanting a dopant of a second conductivity into the first sidewall, and angularly implanting a dopant of a second conductivity into the second sidewall. The at least one mesa is converted to a pillar by diffusing the dopants into the at least one mesa. The pillar is then converted to a column by angularly implanting a dopant of the first conductivity into a first sidewall of the pillar, and by angularly implanting the dopant of the first conductivity type into a second sidewall of the pillar. The dopants are then diffused into the pillar to provide a P-N junction of the first and second doped regions located long the depth direction of the adjoining trench. Finally, the trenches are filled with an insulating material.
