修正に好適なレーザ加工装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a processing apparatus for metals, semiconductors, insulators, etc., and particularly to a laser processing apparatus suitable for forming and modifying fine patterns.

があつた。 For example, in the case of printed circuit boards, copper foil is usually pasted on one or both sides of an insulating plate made of glass cloth impregnated with resin and cured, and the copper foil is formed into a wiring pattern by photo-etching. This method had the disadvantage of requiring many photoetching steps.

じやすいという欠点があつた。 In addition, as an example of how to correct pattern pinholes and wire breaks, if we take a printed circuit board as an example,
As shown in the figure, a metal pattern 2 formed on a base material 1 (glass epoxy, glass polyimide, etc.)
(for example, copper), repair the disconnection defect at part a with the repair wire 3,
Electrical connection was secured by welding the bottom part. In this method, it is necessary to align the repair wire 3 with the metal pattern 2, and it is also necessary to weld fine parts after alignment, and pattern deterioration due to alignment with the electrode and heating during connection is a problem. Ta. In addition, the protruding dimension H of the repaired portion during connection has become an obstacle when constructing a laminate, and it has been necessary to keep H extremely small, for example, 50μ or less. In addition, the third method for correcting the remaining pattern is
As shown in the figure, the remaining portion b of the metal pattern 2 (for example, copper) formed on the base material 1 was mechanically removed using a tone knife. This method has the disadvantage that patterns are likely to be missing, fractured, cracked, or otherwise deteriorated during correction.
又、従来技術ではパターンがさらに高密度化さ
れ、具体的にはパターン巾100μm以下になると、
精度上パターン修正方法として適応出来なくなる
という問題がある。 In addition, in the conventional technology, when the pattern becomes more dense, specifically when the pattern width becomes 100 μm or less,
There is a problem in that it cannot be applied as a pattern correction method due to accuracy.

ン修正に応用可能なものと考えられる。 Incidentally, recently, a technique has been reported in which selective plating or etching is applied only to the laser irradiated area, as shown in Japanese Patent Laid-Open No. 55-148797. This technique is considered to be applicable to fine pattern formation and pattern modification.

修正装置として利用する上で障害になるものと考
えられる。 In the conventional technology listed in Japanese Patent Application Laid-Open No. 55-148757,
As shown in FIG. 4, the beam 8 is directly incident into the plating liquid 5, but in this method, changes in the height of the water surface and changes in the refractive index of the water surface occur when the liquid is stirred, the beam is incident, etc. No consideration was given to this. Therefore, the beam 8 is not always focused on the base material 1, which is considered to be an obstacle to use as a fine pattern forming and correcting device.

SUMMARY OF THE INVENTION An object of the present invention is to provide a fine pattern forming and modifying apparatus that can prevent positional deviation when a laser beam enters a solution.

A feature of the present invention is that when performing processing such as pattern formation or correction on a workpiece in a solution, the liquid level of the solution is leveled by using a cover that is sufficiently larger than the laser beam spot and has a portion that transmits the laser beam. By pressing down and positioning the cover so that it is in contact with the solution surface where the laser beam is incident,
The reason is that the solution surface is kept constant.

らも加工効率に大きく寄与する。 A base material 1, which is a ceramic substrate, is placed in a plating solution 5 (for example, an electroless copper plating solution). A beam 8 emitted from the emitted heat 6 of the laser beam is focused onto the workpiece via a condenser lens 7. However, the energy density of the beam 8 is below the density of plating the base material, specifically below 10 2 W/cm 2 . Here, the beam 8 is scanned and a desired pattern is formed on the substrate as scanned. The plating liquid 5 is the beam 8
It is covered with a cover 13 that allows the light to pass through. Therefore, the water surface condition is always constant, and there is no need to take into account changes in the height of the water surface due to stirring or beam irradiation, or changes in the refractive index due to ripples on the water surface, unlike in the case without the cover 13. No blurring occurs. Furthermore, by making the cover 13 U-shaped as shown in the figure, the length l in the solution through which the beam passes can be minimized, and moreover, the solution can be replenished from the side as shown by arrow S. . Furthermore, here,
A short beam transmission length l in the solution indicates that the absorption of the beam by the solution is small, and the fact that the liquid is replenished from the side indicates that the processing speed becomes faster. Both contribute significantly to processing efficiency.

平方向の位置ずれを防止する。 Another embodiment of the invention will be described with reference to FIG. The difference between FIG. 6 and FIG. 5 is that the beam 8 is used to modify the pattern. The printed circuit board having the corresponding disconnection defect at section a is placed in plating solution 5 (for example, electroless copper plating solution). Next, the beam 8 emitted from the laser beam source 6 is focused on the defect a portion via the condenser lens 7, and the broken portion is filled with local plating. The horizontal plane and surface dimensions of the plating liquid 5 are precisely set by the cover 13 through which the beam 8 passes. Cover 13 has beam 8
For Ar, YAG lasers, etc., use quartz glass, etc. Further, the back surface of the defective portion a of the base material 1 is placed in contact with the case 4 . Another embodiment of the invention will be described with reference to FIG. The difference between FIG. 6 and FIG. 5 is that only the periphery of the defect a is immersed in the plating liquid 5 surrounded by a local case 9, and the beam 8 is focused. Rubber pad 10 prevents liquid leakage.
In addition, in order to ensure accurate alignment of the beam, the base material 1 is placed on a fixed base 11 having an exhaust hole 12 for evacuation using a true pump or the like as shown in FIG. 7 as a means to prevent the base material 1 from bending or warping. 1 to prevent the beam 8 from shifting in the vertical direction.

This is aimed at preventing plating deposited on the back side of the base material 1 due to the transmission of the beam 8. In this method, if the defect a has a long dimension, a method of scanning the beam 8 is used. In this case, the method of scanning the beam 8, the base material 1
Either side or the entire plating liquid case may be moved.

The printed circuit board having the corresponding disconnection defect at part a is placed in plating liquid 5. Next, the beam 8 emitted from the laser beam source 6 is scanned onto the pattern 2 via a condenser lens 7. Here, the beam 8 is the surface of the pattern and has a diameter that is equal to or smaller than the line width of the pattern 2. The light reflected on the surface of the pattern 2 passes through the prism 19 and is detected by the reflected light detector 16, converted into an electrical signal, and sent to the control unit 18 via the amplifier 17. The power density of the beam 8 at this time is below the critical power density at which plating reaction occurs, specifically below 10 2 W/cm 2 .
