## Abstract

A package for holding metal-ceramic substrates, the package includes a tray manufactured from a flat material with at least one holder adapted to a format of the metal-ceramic substrates for holding the metal-ceramic substrates, an interior of the at least one holder of the tray being defined by a bottom and circumferentially by an edge and by at least one covering completely accommodating the tray, and the tray is sealed vacuum-tight by the covering and the covering has an interior accommodating the tray, and the tray is impinged with a vacuum so that the metal-ceramic substrates are fixed in the at least one holder by clamping on an edge-side of the tray by forces (F) exerted on the edge resulting from the ambient pressure.

## Claims

### Claim 1

A package and a plurality of stacked metal-ceramic substrates held within the package, comprising:
the plurality of stacked metal-ceramic substrates, each of the plurality of stacked metal-ceramic substrate consisting of a ceramic layer and a plurality of single metallizations formed on at least one surface side of the ceramic layer, the plurality of stacked metal-ceramic substrates having break-off lines extending between the plurality of single metallizations;
a tray comprising at least one holder adapted to a format of the plurality of stacked metal-ceramic substrates holding the plurality of stacked metal-ceramic substrates, wherein a depth of the at least one holder is such that the plurality of stacked ceramic metal substrates are stacked such that one of the plurality of stacked metal-ceramic substrates is positioned above another of the plurality of stacked metal-ceramic substrates, and the plurality of stacked metal-ceramic substrates fit entirely within the at least one holder, the at least one holder having an interior defined by a bottom and circumferentially by an circumferential edge, the at least one holder is provided circumferentially with corner recesses and edge areas forming the circumferential edge and the corner recesses and the edge areas merge into each other to form a U-profile that is open toward the bottom side of the tray, the U-profile being defined by a circumferential first wall section forming an outer surface of the circumferential edge, a second wall section circumferentially limiting at least one holder and forming an inner surface of the circumferential edge, and a third wall section connecting the first wall section and the second wall section in a yoke-like manner; and
the tray also includes a covering completely enclosing the plurality of stacked metal-ceramic substrates located in the holder, wherein the tray is evacuated to vacuum seal the covering about the plurality of stacked metal-ceramic substrates so that the plurality of stacked metal-ceramic substrates are fixed in the at least one holder by clamping on an edge-side of the tray by forces (F) exerted on the circumferential edge resulting from ambient pressure created by the vacuum.

### Claim 2 (depends on 1)

The package according to claim 1, wherein the tray has projections on an outer side of the circumferential edge.

### Claim 3 (depends on 1)

The package according to claim 1, wherein outer dimensions of the tray ranges from 208 to 238 mm and inner dimensions the at least one holder ranges from 127 to 179 mm.

### Claim 4 (depends on 1)

The package according to claim 1, whereby the tray has a rectangular shape, a sub-space of the at least one holder has an effective width on the circumferential edge of the tray on a longer side that is approximately 19% to 20% of a width of the tray, and the sub-space of the at least one holder has on a narrower side or edge area having a width of the circumferential edge on a narrower sides of the tray that is approximately 12% to 13% of an outer dimension of the tray on a longer side.

### Claim 5 (depends on 1)

The package according to claim 1, wherein the covering consists of a weldable plastic foil.

### Claim 6 (depends on 1)

The package according to claim 1, wherein the circumferential edge has a width of from 5-45 mm.

### Claim 7 (depends on 1)

The package according to claim 1, further comprising a leg projecting from the first wall section of the circumferential edge and forming a circumferential edge section, the circumferential edge section being rounded on the corners of the tray, with a radius between 1.5 and 40 mm.

### Claim 8 (depends on 1)

The package according to claim 1, wherein the tray further comprises at least two holders for the plurality of stacked metal-ceramic substrates, the at least two holders being arranged in at least one row, the at least one row extending parallel to one circumferential side of the tray, and the at least two holders of the at least one row being formed by a joint recess on a tray top side, the joint recess has a reduced width or depth at a transition between the at least two holders.
