摘要:
A non-volatile memory device includes a dielectric layer between a charge storage layer and a substrate. Free bonds of the dielectric layer can be reduced to reduce/prevent charges from leaking through the free bonds and/or from being trapped by the free bonds. As a result, data retention properties and/or durability of a non-volatile memory device may be enhanced.

Methods of forming an insulating film include forming an insulating film on a substrate. A first impurity is injected into the insulating film using a thermal process under a first set of processing conditions to form a first impurity concentration peak in a lower portion of the insulating film. A second impurity is injected into the insulating film using the thermal process under a second set of processing conditions, different from the first set of processing conditions, to form a second impurity concentration peak in an upper portion of the insulating film. Injecting the first impurity and injecting the second impurity may be carried out without using plasma and the first impurity concentration peak may be higher than the second impurity concentration peak.

Methods of forming a semiconductor device having stacked structures include forming a first semiconductor structure on a substrate and forming a first interlayer insulating layer on the substrate. The first interlayer insulating layer has a substantially level upper face. A semiconductor layer is formed on the first interlayer insulating layer and a first gate insulation layer is formed on the semiconductor layer at a processing temperature selected to control damage to the first semiconductor structure. A second semiconductor structure is formed on the first gate insulation layer.

Fin-Field Effect Transistors (Fin-FETs) are provided. A fin is provided on an integrated circuit substrate. The fin defines a trench on the integrated circuit substrate. A first insulation layer is provided in the trench such that a surface of the first insulation layer is recessed beneath a surface of the fin exposing sidewalls of the fin. A protection layer is provided on the first insulation layer and a second insulation layer is provided on the protection layer in the trench such that protection layer is between the second insulation layer and the sidewalls of the fin.
摘要:
The present invention is directed toward a structure and method by which trench isolation for a wide trench and a narrow trench formed in first and second regions of a substrate may be achieved without formation of a void in an isolation layer, a groove exposing an isolation layer, or an electrical bridge between gates in a subsequent process. A lower isolation layer is formed on the substrate in a first and second trench. The lower isolation layer is patterned to fill a lower region of the first trench, and an upper isolation pattern is formed to fill the second trench and a remainder of the first trench. An aspect ratio of first trench is reduced, thereby preventing the occurrence of a void in the upper isolation layer, or a gap between the upper isolation layer and the substrate.
