Abstract: There is provided a syringe filled with a resin composition which prevents a barrel cap from being detached due to temperature change during storage or during transportation, a production method thereof, and a storage method thereof. This syringe filled with the resin composition includes a syringe having a syringe barrel, a resin composition filling the syringe barrel, a plunger inserted in the syringe barrel, a barrel cap blocking an opening of the syringe barrel, and a spatial part between the plunger and the barrel cap in the syringe barrel. The pressure of the spatial part in a frozen state is 50 kPa to 92 kPa.

Abstract: An object of the present invention is to provide a semiconductor device in which peeling between a mold resin and a substrate is suppressed. A semiconductor device 1 includes a semiconductor chip 20 and a substrate 10 that are molded with a mold resin layer 40. The semiconductor device 1 includes a resin layer 50 having a thickness of 200 nm or less different from the mold resin layer 40 between the cured mold resin layer 40 and the substrate 10. The resin layer 50 present between the mold resin layer 40 and the substrate 10 is preferably present on a periphery of 30% or more of the chip when an entire peripheral length of the chip is 100%.

Abstract: There are provided a syringe filled with a resin composition and a storage method thereof. According to the syringe and the storage method, mixed air, which causes the resin composition to be intermittently discharged from the syringe, is suppressed. The syringe filled with the resin composition includes a syringe, a resin composition filling the syringe, and a plunger. The resin composition contains voids. The ratio of the volume of the voids relative to the volume of the resin composition is 1.0 ppm by volume to 520 ppm by volume. The voids have a maximum diameter of 2,500 μm or less.
