A marking process of an object comprising providing a processing device/unit/member/circuit having a word processing software and a display and operationally connected to an apparatus for the marking of an object having a marking head, entering one data by the word processing software suitable for being engraved on an object, switching on a detecting device/unit/member/circuit which are positioned above a work top of the apparatus to receive the object to be marked, positioning the object to be marked above the work top, acquiring an image of the object to be marked and sending it to the word processing software to show it on the display, checking via the display whether the data entered is at least partly superimposed on the image of the object, and starting the marking of the object.

A press frame includes a lower press frame, an upper press frame that supports a press mechanism, and a vertical press frame. A laser frame includes a lower laser frame, an upper laser frame that supports a laser mechanism, and a vertical laser frame. A transport space for a workpiece in the press frame and a transport space for the workpiece in the laser frame communicate with each other, the transportation in the spaces being performed by a transporter. The upper laser frame includes a joint extending from the vertical laser frame toward the upper press frame side while being spaced from the upper press frame, and that switches between a connected state where the upper press frame and an end of the upper laser frame are connected and a separated state where the connection therebetween is released.

A multifunctional shaft apparatus includes a shaft base, a spindle, a tool holder, an ultrasonic vibration assembly, a laser light source and a mirror assembly. The spindle is disposed in the shaft base. The spindle has a laser channel extending along the spindle. The tool holder is disposed on the spindle. The tool holder has a hollow passage, an inner space and a recessed portion. The hollow passage is communicated with the laser channel. An inner wall of the hollow passage has at least one through hole communicated with the inner space, and the recessed portion is disposed on a bottom surface of the tool holder. The bottom surface has a light outlet. The ultrasonic vibration assembly includes a vibration member disposed in the recessed portion. The mirror assembly is disposed in the tool holder and is configured to reflect the laser light beam generated by the laser light source.

A wafer composite includes a handle substrate, an auxiliary layer formed on a first main surface of the handle substrate, and a silicon carbide structure formed over the auxiliary layer. The handle substrate is subjected to laser radiation that modifies crystalline material along a focal plane in the handle substrate. The focal plane is parallel to the first main surface. The auxiliary layer is configured to stop propagation of microcracks that the laser radiation may generate in the handle substrate.
