摘要： The optical data storage medium (20) has a substrate (1) with a surface area having tracks (4) of marks representing stored information. The information is readable by means of a scanning radiation beam (10). A reflective layer (2) is present, reflecting the radiation beam (10). The medium has a radiation beam (10) reflection larger than 50 %. The reflective layer (2) comprises a compound of the formula Al100-yXy, in which formula Al is aluminum and X is an element selected from the group of Ge and Si. The letter y is the atomic fraction of X in at. %. The value of y is in the range 5

摘要： The electronic device (1) has a layer (11) of a material comprising a first and a second element. This material has an amorphous and a crystalline state. A transition from the amorphous to the crystalline state can be effected by heating of the material to above a crystallization temperature, for example with a laser. As a result, the layer (11) has a first electrically conducting areas (21), comprising the material in the crystalline state, which are insulated from each other by the first electrically insulating area (23), comprising the material in the amorphous state. The layer (11) may be present as an interconnect layer, but also as a covering layer. Preferably, the material is aluminum-germanium. In the method of patterning a layer (11), electrically conductive areas of the layer can be strengthened by electroplating.

摘要： The passive component (1) has a first part (22) of a material with a first resistance value, which value can be lowered to a second value by laser trimming. The second value is at most one tenth of the first value and preferably less. Said material crystallizes in a laser trimming process, which locally heats the material to at least a transition temperature. Said material contains at least two different elements, which are preferably aluminum and germanium. The passive component (1) may be, for example, a resistor or a capacitor and may be part of a thin-film network of resistors, capacitors and/or inductors. In a resistor, it is preferred to have a second part (4) which contains a different resistance material with a resistance value lower than the first value and preferably higher than the second value.
