摘要： A method of forming a semiconductor device includes depositing a fill material (4) on a substrate portion (2) and on a dielectric layer (3) being disposed on the substrate (1) and having an opening (10) located above the substrate portion (2), removing the fill material (4) disposed above the dielectric layer (3), thereby leaving an exposed top surface (6) of the dielectric layer (3) and residual fill material (15) within the opening (10), forming a hard mask material (5) on the exposed top surface (6) of the dielectric layer (3) and on the residual fill material (15), patterning the hard mask material (5) for forming a hard mask (25) having trenches (8a, 8b) extending along a lateral direction (X) and exposing portions of the residual fill material (15) adjacent to the dielectric layer (3) and portions of the dielectric layer (3) adjacent to the residual fill material (15), anisotropically etching the dielectric layer (3), the residual fill material (15) and the substrate (1) selectively to the hard mask (5), thereby forming at least a first and a second isolation trench (11a, 11b) extending along the lateral direction (X).

摘要： A method for fabricating a semiconductor structure includes providing a semiconductor substrate, providing a plurality of trenches in the semiconductor substrate using a first hard mask, and causing the hard mask to recede by a predetermined distance with respect to the trench wall at the top side of the semiconductor substrate for forming a first hard mask that has been caused to recede. An isolation trench structure is provided in the semiconductor substrate using a second hard mask, the isolation trench structure subdividing the first first hard mask that has been caused to recede along rows into strip sections and the strip sections of adjacent rows being arranged offset with respect to one another. The receding process results in a reduction of an overlap region between two strip sections of adjacent rows in comparison with an overlap region which would be present without the receding process. The second hard mask is removed and the isolation trench structure is filled and planarized with a filling material using the first hard mask subdivided into the strip sections.

摘要： To fabricate a hole trench storage capacitor having an inner electrode, which is formed in a hole trench, and an outer electrode, which is formed in an electrode section, surrounding the hole trench in a lower section, of the semiconductor substrate, the inner electrode is continued above the substrate surface of the semiconductor substrate. Then, an additional layer, which widens the semiconductor substrate, is grown onto the substrate surface by an epitaxy process. A transition surface for contact-connection of the inner electrode and at least a part of an insulation collar is formed above the original substrate surface, thereby increasing the size of a surface area of the hole trench storage capacitor, which can be used for charge storage, while using the same aspect ratio for an etch used to form the hole trench.

摘要： In a method for producing a trench transistor, a substrate of a first conduction type is provided and a trench in the substrate and a gate dielectric in the trench are formed. A first conductive filling in the trench as a gate electrode on the gate dielectric and first source and drain regions are formed. An etched-back first conductive filling is produced by etching back the first conductive filling down to a depth below the first source and drain regions and second source and drain regions are formed. The second source and drain regions adjoin the first source and drain regions and extend to a depth at least as far as the etched-back first conductive filling. An insulation spacer above the etched-back first conductive filling is formed in the trench and a second conductive filling is provided in the trench as an upper part of the gate electrode.

摘要： A description is given of a method for a selective masking of a structure with a small structure surface with respect to a structure with a larger structure surface. To that end, the structures are filled with a covering layer. The covering layer is formed with a larger thickness above the first structure, which has the larger structure surface, than above the second structure. Afterward, the covering layer is removed by a homogeneous removal method, so that first the structure surface of the second structure is uncovered. A simple self-aligning method for fabricating a mask for uncovering the second structure is thus provided.

摘要： A method for etching trenches having different depths on a semiconductor substrate includes providing a mask with first and second openings. The first and second openings are located where corresponding first and second trenches are to be etched. A slow-etch region, made of a slow-etch material, is provided above the substrate at a location corresponding to the second opening. When exposed to a selected etchant, the slow-etch material is etched at a rate less than the rate at which the semiconductor substrate is etched when exposed to the selected etchant.
