次の様な対策が採られている。One of the conventional methods for sealing a semiconductor element is to place a pellet composition prepared by molding epoxy resin powder into a predetermined size onto the semiconductor element, and then heat and melt the composition to cover the semiconductor element. In order to perform this inorganic melt sealing, it is necessary for the epoxy resin powder to flow sufficiently after melting, and therefore it is necessary to slow down the reaction rate of the epoxy resin. Conventionally, the following measures have been taken for this purpose.

■反応速度の遅い硬化剤を選択使用する。■Select and use a curing agent with a slow reaction rate.

It has the disadvantage of poor quality and lack of stability in terms of quality.

ンを代表例として説明すると、次の通りである。The crystalline epoxy resin used in the present invention has a melting point of 5.
It is a solid crystalline epoxy resin having a temperature of 0 to 150°C, and so-called crystalline epoxy resins that have been conventionally used in this type of field can be widely used. Particularly in the present invention, an epoxy resin having a melt viscosity of 5 poise or less at a temperature 10° C. higher than its melting point is preferred. Specific examples of these include:
For example, 4.4', -bis(2,3-epoxypropoxy)-3,3', 5. Examples include 5'-tetramethylbiphenyl, diglycidyl terephthalate, and diglycidyl hydroquinone. More specifically, diglycidyl hydroquinone represented by the following general formula (1) will be explained as a representative example as follows.

２０％以下好ましくは５％以下含んでいても良い。(1) Diglycidylhydroquinone is a compound of formula (I) in which the number of repeating units is n=o, and has crystallinity. However, in the present invention, the composition may contain 20% or less, preferably 5% or less of a compound where n is about 1 to 5 or a compound whose terminal is not epoxidized.

In the case of H3, the melting point is 105 to 107°C, and when it is melted, it exhibits a very low viscosity of about 0.02 poise or more at 150°C.

は８０〜１２０℃程度である。In the present invention, as the crystalline epoxy resin, one with a melting point of 50 to 150°C is used as explained above, but in this case, if the melting point does not reach 50°C, the target powder composition will not block. This tends to occur, and conversely, when the temperature is higher than 150°C, workability tends to deteriorate. A preferable melting point is about 80 to 120°C.

It is preferable to set it within the range of 1.5 to 1.5. At this time, if the amount is outside the above range, the reaction will be difficult to occur sufficiently, and the properties of the cured product will tend to deteriorate.
