- FIG. 2 shows an exemplary embodiment of a perforated disk 23 in a plan view, as for example on a Wafers or benefits produced hundreds of times side by side can be.
- the perforated disc 23 is as flat, circular component executed, the several, for example, three, axially consecutive Functional levels or layers has. From a bottom Function level 35 are started e.g. two more Function levels 36 and 37 built on it, where also in a single electroplating step several functional levels can be generated by means of so-called lateral overgrowth.
- the upper functional level 37 has a rectangular shape Inlet opening 40 with the largest possible extent. With z. B. in each case the same distance to the valve longitudinal axis 2 and thus to the central axis of the perforated disc 23 and around this for example, are arranged symmetrically in the lower functional level 35 four square outlet openings 42 provided.
- the outlet openings 42 are at a Projection of all functional levels 35, 36, 37 into one plane with an offset outside the inlet opening 40.
- the Offset can be in different directions be different in size.
- a channel 41 (cavity) formed, which represents a cavity.
- the one circular contour having channel 41 has such Size that he is in the projection the inlet opening 40 and the outlet openings 42 completely covered.
- the z. B. of metal titanium, copper), Silicon, glass or ceramic can exist.
- On the Support plate is optionally at least one first Auxiliary layer on galvanized. It is about for example, an electroplating starting layer (eg Cu), the to the electric wire for the later micro electroplating is needed.
- the electroplating starter layer can also be used as Sacrificial layer serve to later a simple separation of the To allow perforated disk structures by etching.
- the Applying the auxiliary layer (typically CrCu or CrCuCr) happens z. B. by sputtering or by electroless Metal deposition. After this pretreatment of Carrier plate is a photoresist on the auxiliary layer (Photoresist) applied over the entire surface.
- the thickness of the photoresist should be the thickness of the Metal layer, in the later following Galvanic process is to be realized, ie the thickness of the lower layer or functional plane 35 of the perforated disc 23rd
- the metal structure is to be realized with the help of a Photolithographic mask inverse in the photoresist be transmitted.
- One possibility is to use the Photoresist directly over the mask by UV exposure Exposure (UV depth lithography).
- the ultimately resulting in the photoresist negative structure for later functional level of the perforated disc 23 becomes galvanic filled with metal (eg Ni, NiCo) (metal deposition).
- the metal lays down tightly by galvanizing Contour of the negative structure so that the given Contours are faithfully reproduced in it.
- two functional levels in one Electroplating step are generated (lateral overgrowth).
- the layers of a perforated disc 23 can also different metals are used, but only in can be used in each case a new electroplating step.
- the separation of the perforated discs 23 takes place.
- the sacrificial layer is etched away, causing the Lift off the perforated discs 23 from the carrier plate. After that will be the electroplating starting layers removed by etching and the Remaining photoresist from the metal structures removed.

To the separation of the perforated discs 23 of the support plate These are for their respective application for installation in front. The inner opening structure of such However, microgalvanized component is then not more accessible. For testing and measuring purposes, however, should at least randomly a very simple and cost-effective way to measure the components be created.
- Perforated discs 23, such as one in Figure 2 can be shown so far only with the help of destructive manufacturing processes are checked and measured become. This requires the components selected for remeasurement be embedded and polished in a complex manner. By grinding the completely manufactured components can disadvantageously create burrs that the Can falsify the measurement result. There is also one increased risk of deformation of the components to be measured when embedding and sanding.
- Photoresist areas 45 which are also called Lackstege or Lackkerne can be characterized, built-in.
- the Installation of targeted photoresist areas 45 is about specially shaped masks on the selected components 23 ' made from the outset, so that the Metal structure starting from the lower functional level 35 already growing along this photoresist area 45.
- the selected components 23 ' are thus in their Entire structure desired discontinuously produced (FIG. 3). After the dissolution of the photoresist region 45 are the internal structures of the respective component 23 'to simple Way exposed.
- the Place photoresist area 45 in such a way that he can Opening structures cuts after manufacture to be measured.
