    摘要: Producing a vertical transistor includes providing a conductive gate structure having a reentrant profile on a substrate. A conformal dielectric material layer is formed on the conductive gate structure. A conformal semiconductor material layer is formed on the dielectric material layer, over the conductive gate structure. An electrode is formed located over the conductive gate structure and in contact with a first portion of the semiconductor layer and another electrode is formed vertically separated from the electrode and located in contact with a second portion of the semiconductor layer by printing an inhibitor that wicks along the reentrant profile of the conductive gate structure and depositing a conductive inorganic thin film using an atomic layer deposition process where the inhibitor is absent to form a channel in the semiconductor layer along the reentrant profile between the electrodes by inhibiting deposition of conductive material between the electrodes with the wicked inhibitor.

    摘要: A structure is provided herein which includes an array of trench capacitors having at least portions disposed below a buried oxide layer of an SOI substrate. Each trench capacitor shares a common unitary buried capacitor plate which includes at least a portion of a first unitary semiconductor region disposed below the buried oxide layer. An upper boundary of the buried capacitor plate defines a plane parallel to a major surface of the substrate which extends laterally throughout the array of trench capacitors. In a particular embodiment, which starts from either an SOI or a bulk substrate, trenches of the array and a contact hole are formed simultaneously, such that the contact hole extends to substantially the same depth as the trenches. The contact hole preferably has substantially greater width than the trenches such that the conductive contact via can be formed simultaneously by processing used to form trench capacitors extending along walls of the trenches.

    摘要: The present invention relates to a semiconductor device that contains at least one trench capacitor and at least one vertical transistor, and methods for forming such a semiconductor device. Specifically, the trench capacitor is located in a semiconductor substrate and comprises an outer electrode, an inner electrode, and a node dielectric layer located between the outer electrode and the inner electrode. The vertical transistor is located over the trench capacitor and comprises a source region, a drain region, a channel region, a gate dielectric, and a gate electrode. The channel region of the vertical transistor is located in a tensilely or compressively strained semiconductor layer that is oriented perpendicularly to a surface of the semiconductor substrate. Preferably, the tensilely or compressively strained semiconductor layer is embedded in an insulator structure, so that the vertical transistor has a semiconductor-on-insulator (SOI) configuration.

    摘要: A method of forming a vertical transistor trench memory cell having an insulating ring is provided. The method includes forming a semiconductor material region in an etched portion of a semiconductor substrate; partially etching the semiconductor material region to form a deep trench, where the deep trench extends beyond the semiconductor material region, and where the remaining of the partially etched semiconductor material region defines an insulating ring. A vertical transistor is then formed in the deep trench, such that the vertical transistor is isolated by the insulating ring. A semiconductor structure is also provided. The semiconductor structure includes a first and a second trench memory cells formed on a semiconductor substrate; and an insulating ring surrounding each of the first and second trench memory cells. The insulating ring is configured for significantly enclosing out diffusions from the trench memory cells.
