2. Description of the Related Art Conventionally, a semiconductor light receiving sensor is mounted on a semiconductor device.
2. Description of the Related Art A method of housing and sealing in a sealed container formed of ceramic, resin, or the like has been widely used. FIG. 6 shows an example.

[0003] The semiconductor wafer 1 on which the light receiving sensor 4a and the like are mounted is cut into a predetermined chip shape, and is adhered and fixed to a sealing container 8a formed integrally with a metal lead 8b in advance. After connecting the semiconductor wiring circuit 4c and the metal lead 8b with the metal wire 9, the light transmitting protection member 6 mainly made of a glass plate is adhered to the sealing container, and the light receiving sensor is hermetically sealed.

However, the above-described conventional mounting method has the following problems.

[0005] 1. It is necessary to arrange a sealing container, a protective member, and the like around the semiconductor chip, and these restrict the miniaturization of a device to which the light receiving sensor is applied.

[0006] 2. Since the semiconductor wafer is cut into predetermined chips in advance, adhered to a sealing container, and passed through a wire connection process, dust easily adheres to the light receiving sensor during handling. Since each light receiving sensor is several micrometers in size, even a small amount of dust causes an image defect, which leads to a reduction in yield and an increase in manufacturing cost.

[0007] 3. The relative position accuracy between the outer shape of the protective member or the sealed container and the light-receiving sensor is generally determined by a combination of the molding accuracy of each member and the assembly accuracy by bonding or the like.
It is about 0.1 to 0.01 mm. On the other hand, the relative position accuracy between the light receiving sensor and the optical system is ±
In many cases, about 0.01 to 0.001 mm is required.

Since the light receiving sensor is housed and sealed in the protective member, it cannot be touched directly. Therefore, generally, an adjustment mechanism is provided between a member of the optical system and a sealing container or the like, and alignment is performed with reference to the output of the light receiving sensor.
