本発明は紫外線消去型半導体装置に係り、特に紫外線を
通す透光部構造に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an ultraviolet erasable semiconductor device, and more particularly to a light-transmitting structure that transmits ultraviolet rays.
従来例の構成とその問題点

込み可能な半導体記憶装置(以下、EP’−ROMと略
す)が多く用いられている。2. Description of the Related Art Structures of Conventional Examples and Their Problems Recently, ultraviolet erasable erasable and writable semiconductor memory devices (hereinafter abbreviated as EP'-ROMs) have been widely used in information processing devices and the like.

ある。Conventionally, EP-ROMs have been sealed in a ceramic case 1, as shown in the cross-sectional view of Figure 1 (A), or as shown in the plan view and cross-sectional view of Figures 1 (B) and (C). Generally, they are made using a plastic case.

わゆる裏面側に外部リード8,25を引き出していた。That is, conventionally, a glass window 3 or a transparent body 27 was placed on the F of the EP-ROM chip 1 or 22, and the external leads 8, 25 were drawn out to the opposite side, the so-called back side.

光部表面のくもり等の汚染が加わり易く、紫外線の消去
特性が悪くなる等の問題もあった。In the conventional structure, when an EP-ROM is inserted into a printed circuit board or a set circuit board, a transparent part such as a glass window or a transparent body comes out to the surface, so during actual operation, ultraviolet rays are absorbed from the outside. It was necessary to cover the surface of the light-transmitting part with another light barrier so that the stored contents would not be damaged by reaching the EP-ROM chip through the light-transmitting part. Further, there are also problems in that the surface of the light-transmitting portion is easily contaminated by clouding, and the erasing characteristics of ultraviolet rays are deteriorated.

A metal lid (or ceramic lid) 44 having a glass window 43 on the lower side of the case 42 is filled with a brazing material (or low melting point glass) 45
It has a hermetically sealed structure. In the figure, 46 is a chip stage, 4 is an internal wiring, and 48 is an external lead, and the tip of the external lead 48 is exposed to the window side with respect to the chip 41. 49 is bonding
A wire 50 is a bonding pad, 51 is a gold-silicon (Au-Si) alloy, and 62 is a metallized portion. In FIG. 2(B), a light transmitting body 67 is provided below the EP-ROM chip 62, and the lower surface of the light transmitting body 6γ is exposed on the lower surface of the molding resin 69. External leads 65 protrude from the chip 62 on the same side as the transparent body 67 . In the embodiment shown in FIG. 2 (c+), the periphery of the EP-ROM chip 82 is molded with a silicone resin 87 that transmits ultraviolet rays, and a portion of it is further molded into a predetermined shape with a resin 88 such as epoxy. In this case, the lower surface of the silicone resin 87 covering the chip is exposed on the lower surface of the mold resin 88. 85 is an external lead, which is bent to the same side as the silicone resin 87 with respect to the chip 82.

付けられる。As described in detail, according to the present invention, ultraviolet erasable E
By making the P-ROM pin-compatible with conventional products and protruding the metal lead on the same side as the glass window or transparent material that allows ultraviolet rays to pass through, the glass window or transparent material can be exposed to the surface when this EP-ROM is actually used. It can be installed so that it appears on the back side without any problems.

透過性が悪くなることもほとんど起らない。Therefore, the stored contents of the EP-ROM are not erased by unnecessary ultraviolet rays, and the surface of the transparent part made of a glass window or transparent material becomes scratched during use, resulting in poor ultraviolet ray transmittance. It almost never happens.
