摘要:
A metallization surface (5), which acts as an etching stop layer during the production of openings (4) in a passivation layer (3) applied to its upper face and protects an interconnect structure (6) arranged underneath it, is arranged in an uppermost metallization level (1). A further opening is produced in the metal surface (5), through which a focused ion beam is aimed at the interconnect structure (6) in order to connect interconnects to one another and/or to interrupt at least one interconnect. The wiring of the integrated circuit can thus be varied individually, starting from identically produced semiconductor chips.

An exemplary combustor includes at least a portion having an inner liner and an outer cover plate, which together form an interposed cooling chamber. A plurality of hollow elements extend from the liner and protrude into the cooling chamber. Each hollow element defines a damping volume connected to an inner volume of the combustion chamber via a calibrated duct. During operation, the hollow elements damp pressure pulsations and, in addition, also transfer heat.

The invention relates to a novel operating method and corresponding ballast for illuminating systems having temporally sequential color filtering and a high-pressure discharge lamp operated by alternating current. In this case, at least three commutations of the lamp current are used within a color filtering sequence, in order to be able to operate the lamp advantageously without an excessive increase in the operating frequency of the color filter system.
