Definitions
- a compulsory layer is arranged on the uppermost layer of the layer stack before sintering, which is attached to the layer stack by penetration of the sintering aid of the uppermost layer of the layer stack into the compulsory layer during sintering. After sintering, the constraint layer is removed again. Removing the compulsory layer can be done, for example, by scraping or sputtering.
- a rigid layer in the form of a sintered Al2O3 plate or a flexible layer in the form of a green sheet, which itself does not contain any sintering aids and which consequently does not sinter during the sintering of the layer stack, can be considered as the layer.
- a flexible constraint layer is known, for example, from the publication DE 691 06 830 T2.
- a flexible constraint layer can be, for example, a green sheet that contains Al2O3 grains and a polymeric binder.
- the use of the method according to the invention for the production of ceramic substrates in particular enables the use of layer stacks which have the shape of a plate, the plate having a base area of at least 18 cm ⁇ 18 cm and a height of 0.5 to 3 mm.
- a plate can be used to produce a large-area substrate in a single production step, or a large number of small substrates by subsequently dividing the large-area substrate.
- a reaction layer which contains sintering aids from the layer with the high proportion of unchanged residues of a sintering aid can in particular be arranged between the layer with the increased proportion of unchanged residues of sintering aid.
- the reaction layer contains ceramic material and sintering aids from the adjacent layer.
- the reaction layer can have a thickness between 10 and 50 ⁇ m. The reaction layer is thus considerably thicker than the reaction layers which are produced by the known method.
- Figure 3 shows an example of a ceramic substrate during its manufacture by the method according to the invention in a schematic cross section.
- the number of layers 3 is six.
