Abstract:
The invention relates to a method for producing thin metal-containing layers (5C) having low electrical resistance, according to which a metal-containing initial layer (5A) having a first grain size is configured on a carrier material (2) in a first step. A locally restricted heated area (W) is then created and moved within the metal-containing initial layer (5A) in such a way that the metal-containing initial layer (5A) is recrystallized so as to create the metal-containing layer (5C) having a second grain size which is enlarged to the first grain size, whereby a metal-containing layer having improved electrical properties is obtained.
Abstract:
The invention relates to a method for producing thin metal-containing layers having a low electrical resistance during which a metal-containing layer (5') having a first grain size is firstly formed until it has a first thickness (d1). Once this thickness (d1) is attained, a recrystallization is subsequently carried out in order to produce a metal-containing layer (5'') having an increased grain size. Afterwards, the metal-containing layer (5'') having the increased grain size is thinned until it has a desired target thickness (d2) whereby obtaining a very thin metal-containing layer having a reduced electrical resistance.

The invention relates to a method for producing an integrated capacitor consisting of the following steps: namely, the formation of a structured metal layer (1) on a supporting layer (2); covering the structured metal layer (1) and the supporting layer (2) with a thick dielectric layer (3); carrying out a local etching through the thick dielectric layer (3) until reaching the structured first metal layer (1) in order to form an etched opening having a lateral wall surface (4) and a bottom surface (5), which is formed by the exposed surface of the structured first metal layer (1); precipitating a first conductive layer (7) on the formed bottom surface (5) and on the thick dielectric layer (3); precipitating a thin dielectric layer (8) on the first conductive layer (7); precipitating a second conductive layer (9) on the thin dielectric layer (8), and; forming a structured second metal layer (10) on the second conductive layer (9).
Abstract:
The invention relates to a method for producing an integrated circuit arrangement (100) comprising a capacitor (112). A dielectric layer (160) is structured with the aid of a hard mask during a two-stage etching process. The hard mask is subsequently removed if it is an electrically insulating hard mask. If the latter is an electrically conductive hard mask, parts of said mask can remain in the circuit arrangement (100). The integrated circuit arrangement can thus be produced without complex cleaning steps and in addition, the quality of the dielectric in the capacitor is extremely high.
Abstract:
The invention relates to a layer assembly and to a method for producing a layer assembly. This layer assembly comprises a layer that is placed on a substrate. Said layer comprises a first partial region, which is made of a decomposable material, and an adjacent second partial region with a useful structure made of a non-decomposable material. The layer assembly also has a top layer which is arranged on the layer made of a decomposable material and the useful structure. The layer assembly is designed so that the decomposable material can be removed from the layer assembly.

Low modulus dielectric layers (216, 222, 232) are disposed over a workpiece (212). Support structures (218, 226, 236) are formed in the low modulus dielectric layers (216, 222, 232), and support vias (224, 234) are formed between the support structures (218, 226, 236). A high modulus dielectric film (220, 230) is disposed between each low modulus dielectric layer (216, 222, 232), and a high modulus dielectric layer (256) is disposed over the top low modulus dielectric layer (232). Contact pads (204) are formed in the high modulus dielectric layer (256). Each support via (234) within the low modulus dielectric layer (232) resides directly above a support via (224) in the underlaying low modulus dielectric layer (222), to form a plurality of via support stacks within the low modulus dielectric layers (216, 222, 232).
