摘要： The invention relates to a method for fabricating in particular a TMR element for use in a MRAM, wherein a mask is arranged on a substrate and structured in such a manner that it shadows but does not cover a surface region of the substrate, and wherein material of the structure which is to be fabricated is then deposited on the substrate in a directed deposition process. The invention also relates to a component with a micro-technical structure which has been fabricated in this manner.

摘要： A method for producing a microelectronic structure is suggested in which a layer structure (30) which partially covers a substrate (5) and which comprises at least one first conductive layer (15,20) which reaches to a side wall (35) of the layer structure (30), is covered with a second conductive layer (45). The second conductive layer (45) is then subsequently back-etched to as great an extent as possible with an etching process with physical delamination, wherein delaminated material deposits on the side wall (35) of the layer structure (30). On the side wall (35) the delaminated material forms a protection layer (60) by means of which the first conductive layer (15,20) is to be protected from attack by oxygen to the furthest extent possible.

摘要： A structure having air gaps between interconnects is disclosed. A first insulating material is deposited over a workpiece, and a second insulating material having a sacrificial portion is deposited over the first insulating material. Conductive lines are formed in the first and second insulating layers. The second insulating material is treated to remove the sacrificial portion, and at least a portion of the first insulating material is removed, forming air gaps between the conductive lines. The second insulating material is impermeable as deposited and permeable after treating it to remove the sacrificial portion. A first region of the workpiece may be masked during the treatment, so that the second insulating material becomes permeable in a second region of the workpiece yet remains impermeable in the first region, thus allowing the formation of the air gaps in the second region, but not the first region.

摘要： Structures and methods of forming crack stop trenches are disclosed. The method includes forming active regions disposed in cell regions of a substrate, the cell regions separated by dicing channels, and forming back end of line (BEOL) layers over the substrate, the BEOL layers being formed over the cell regions and the dicing channels. Crack stop trenches are then formed encircling the cell regions by etching a portion of the BEOL layers surrounding the cell regions. The wafer is diced along the dicing channels.

摘要： In producing a silicon capacitor, hole structures (2) are created in a silicon substrate (1), at the surface of which structures a conductive zone (3) is created by doping and whose surface is provided with a dielectric layer (4) and a conductive layer (5), without filling the hole structures (2). To compensate mechanical strains upon the silicon substrate (1) which are effected by the doping of the conductive zone (3), a conformal auxiliary layer (6) is formed on the surface of the conductive layer (5), which auxiliary layer is under a compressive mechanical stress.

摘要： For manufacturing a multi-layer capacitor, a layer structure (2, 3, 4) is applied onto a substrate (1), said layer structure comprising conductive layers (2, 4) and dielectric layers (3) in alternation and successive conductive layers (2, 4) therein being respectively formed of one of two different materials which are selectively etchable relative to one another. Two openings (6, 8) are produced in the layer structure (2, 3, 4), whereby under-etchings (21, 41 ) are formed in the first opening (6) by selective etching of the one material and are formed in the second opening (8) by selective etching of the other material, so that only the conductive layers (2, 4) of the non-etched material respectively adjoin contacts (91, 92) introduced into the openings (6, 8).
