Abstract

PURPOSE:To provide a light diffusing function in a semiconductor device itself, to reduce in size and to simplify manufacturing steps by composing a light transmission window of a material having the light diffusing function. CONSTITUTION:As a light transmitting window 8, a light diffusing glass window having light diffusing function by itself is employer instead of a conventional transparent glass window. In this case, a light from an external object is directed to the window 8. It is diffused in the step of transmitting it through the window 8, and the diffused light is directed to a semiconductor element 1 in a package. Accordingly, entirely the same function as that in the conventional one is performed as a hue sensor. Thus, since a light diffusing plate is eliminated, it is reduced in size that much, and manufacturing steps are also simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a semiconductor device in which a semiconductor element having a light receiving function is housed in a package.

[Conventional technology]

FIG. 3 is a sectional view showing a conventional semiconductor device of this kind used as a hue sensor installed in a video camera to detect the hue of an object, for example. In the figure, (1) is GaA
A semiconductor element having a light receiving function such as s, (2) is a package that houses the semiconductor element (1) inside, and the lower package (
2a) and an upper package (2b). (3) is a lead frame that penetrates the package (2) in order to draw out the terminal (4) of the semiconductor element (1) to the outside, and (5) is the gap between the package (2) and the lead frame (3). The sealing resin (6) is a transparent glass window as a light transmission window provided in the center of the upper package (2b) to guide light from an external object to the semiconductor element (1). The semiconductor element (1) is formed integrally with RGB 3 on the light incident side.
A filter film is formed that transmits only one of the hue components of the primary colors, and these three types of semiconductor devices are used as a set.

(7) is a light diffusing plate installed on the top surface of the semiconductor device made up of the above components. This part diffuses the light from the subject, and this diffused light passes through the transparent glass window (6) to the semiconductor device. The light is incident on element (1). This prevents the output of the semiconductor device (1) from becoming unstable due to local distribution fluctuations of the incident light beam.

[Problem to be solved by the invention]

Conventional semiconductor devices are configured as described above, so in order to stabilize the characteristics, a separate
It is necessary to provide the light diffusing plate (7), which increases the size of the component and complicates the manufacturing process.

This invention was made to solve the above-mentioned problems, and aims to provide a semiconductor device itself with a light diffusion function, thereby achieving miniaturization and simplifying the manufacturing process.

[Means to solve the problem]

In the semiconductor device according to the present invention, the light transmission window is made of a material having a light diffusion function.

[For production]

Light from the outside enters directly into a light transmission window formed integrally with the package, is diffused here, and reaches the semiconductor element inside the package.

〔Example〕

In the following, an embodiment of the present invention will be explained with reference to the drawings. In Fig. 0, only the light transmitting window (8) is different from the conventional one.

That is, as the light transmitting window (8), a light diffusing glass window which itself has a light diffusing function is used instead of a conventional transparent glass window.

In this case, light from an external object is incident on this light-diffusing glass window (8). And this light diffusing glass window (5
), and this diffused light is incident on the semiconductor element (1).

Therefore, the same function as the conventional hue sensor can be achieved.

This eliminates the need for the conventional light diffusing plate (2), which not only reduces its dimensions but also simplifies the manufacturing process.

FIG. 2 shows another embodiment of the present invention, in which the light transmitting window (8) is composed of a synthetic glass window consisting of a light diffusing glass part (8a) and a transparent glass part (8b). ing. package! The thickness necessary to satisfy the mechanical strength conditions required because it forms a part of 21,
This synthetic glass window (a) is useful when there is a difference in the thickness required to achieve the necessary light diffusion within a predetermined amount of light attenuation.

〔Effect of the invention〕

As described above, in the present invention, since the light transmitting window is made of a material having a light diffusion function, the semiconductor device itself can be provided with a light diffusion function, making it possible to downsize and simplify the manufacturing process.
