Background
Semiconductor devices such as power modules often have a structure in which other components such as mounting components are mounted on components such as a base substrate. In the case where other components are mounted on the components by a mounting apparatus in order to manufacture a specific variety of semiconductor devices, a process recipe (recipe) in which the variety, mounting position, mounting angle, mounting conditions, mounting order, and the like of each component are set for each mounting point on which each component is mounted is created for the specific variety of semiconductor devices before the other components are mounted on the components. The mounting conditions include a moving speed, a mounting speed, and the like. The process recipe is also referred to as a procedure. The mounting machine calls a process recipe created for a specific type of semiconductor device in setup for a specific type of semiconductor device, and mounts another component on the component according to the called process recipe.
In the technique described in patent document 1, a conductor of a predetermined circuit pattern is printed on the back surface of a printed wiring board (paragraph 0012). On the surface side of the printed wiring board, the positions of elements such as an IC, a capacitor, and a buzzer are shown as a pattern drawn by lines (paragraph 0012).
In the technique described in patent document 2, the back surface of the semiconductor chip is marked with information unique to mounting conditions required for mounting, information related to manufacturing of the semiconductor chip, an alignment mark as information for alignment required at the time of mounting, and the like (paragraph 0017-. Further, the mother chip is disposed so that the surface of the mother chip faces upward (paragraph 0024). In addition, the sub chip is aligned with respect to the mother chip in a face-down state in which the surface of the sub chip faces down (paragraph 0024). At this time, information unique to the sub-chip is marked on the back surface of the sub-chip (paragraph 0024). Therefore, alignment of the daughter chip with respect to the mother chip is easily performed based on, for example, an alignment mark in the information (paragraph 0024).

When the semiconductor device 1 is assembled, steps S101 to S108 shown in fig. 3 are performed.
In step S101, the component 103, and the component 105 constituting the semiconductor device 1 are loaded into the processing apparatus. The component 101, the component 103, and the component 105 to be put in are provided in the holder.

For example, all kinds of components constituting a semiconductor device to be mounted in a day may be provided in the holder.
Next, the machining apparatus starts the automatic operation. Thereby, steps S102 to S108 shown in fig. 3 are performed.
In step S102, the conveyor conveys the component 101 from the rack to a predetermined position inside the processing apparatus, and positions and fixes the component 101 at the predetermined position.
In the next step S103, the device reads the identification mark.
In the next step S104, the device acquires information indicated by the read identification mark.
In the next step S105, the suction mounting machine sucks the mounted component mounted on the rack in accordance with the acquired information. The suction mounting machine sucks the mounted components under suction conditions set for each mounted component in the processing device in advance.
In the next step S106, the suction mounting machine moves the suctioned mounted component shaft to the mounting position in accordance with the acquired information.
In the next step S107, the suction mounting machine mounts the mounting component, the shaft of which has been moved to the mounting position, on the mounting position.
In steps S106 and S107, the suction mounting machine performs the axial movement and mounting of the mounted components in accordance with the mounting conditions set for each mounted component in the machining device in advance.
In the next step S108, it is determined whether or not the mounting of all the mounted components is completed. When all the mounting components have been mounted, the assembly of 1 semiconductor device 1 is completed. In a case where the mounting of all the mounted components has not been completed, steps S103 to S108 are executed again.

6 embodiment 5
The semiconductor device according to embodiment 5 differs from the semiconductor device 1 according to embodiment 1 illustrated in fig. 1 and 2, the semiconductor device 2 according to embodiment 2 illustrated in fig. 4 and 5, the semiconductor device 3 according to embodiment 3 illustrated in fig. 6 and 7, or the semiconductor device 4 according to embodiment 4 illustrated in fig. 8 and 9 in the following points.

In the semiconductor device according to embodiment 5, the identification mark is formed by laser printing. Thus, the identification mark is formed with the concave-convex portion, and when the structural member is mounted on the identification mark, the structural member is mounted on the concave-convex portion. This improves the bonding strength of the structural member mounted on the irregularities due to the anchor effect.
The identification mark may be formed by metal vapor deposition. This can suppress the influence of the identification mark on the bondability of the structural member mounted on the identification mark, and can obtain the same bonding strength of the structural member as that obtained when the identification mark is not formed.
In addition, the present invention can freely combine the respective embodiments within the scope of the invention, or appropriately modify or omit the respective embodiments.
Although the present invention has been described in detail, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that numerous modifications not illustrated can be devised without departing from the scope of the invention.
