- thermosetting resin sheet As a method for sealing a semiconductor with a resin, a method using a liquid resin or a molding compound resin is known (Patent Document 1). These methods require dedicated dies and frame jigs and are expensive. Therefore, in recent years, a method of resin sealing using a thermosetting resin sheet has been proposed. The use of the thermosetting resin sheet eliminates the need for a dedicated mold or frame jig, so that cost reduction can be expected, and the semiconductor device manufacturing time can be expected to be shortened.

- the form to be sealed for example, a component mounted on a support plate
- the resin composition tends to deviate depending on the shape, size, mounting position, and the like.
- the inorganic filler is easily segregated, and the amount of warpage may be extremely large because the amount of the inorganic filler in the resin composition after molding varies depending on the location. An increase in the amount of local warpage is a problem because it leads to defects in the process and a decrease in manufacturing yield.

- thermosetting resin sheet having a specific viscosity since the thermosetting resin sheet having a specific viscosity is used, deviation of the resin composition can be prevented, and local warping of the encapsulant can be suppressed. As a result, a stable quality semiconductor device can be provided.
- the support plate may have any one of a substantially rectangular shape having at least one side of 300 mm or more, a substantially square shape having at least one side of 300 mm or more, and a substantially circular shape having a diameter or minor axis of 12 inches or more. preferable. Since the manufacturing method of the semiconductor device of the present invention uses a specific thermosetting resin sheet, the electronic components arranged on these large-area supports can be sealed together in a good manner.
- the electronic component is preferably a semiconductor chip.
- the step (A) includes a step (A-1) of forming a laminate by disposing a thermosetting resin sheet on a chip mounting plate, and a step (A-) of pressing the laminate under reduced pressure. 2). Thereby, voids can be reduced.
- the pressure pressing in the step (A-2) is preferably performed using a parallel plate press. This eliminates the need for a dedicated mold or frame jig required when using a compression molding machine or a transfer molding machine, thereby reducing the manufacturing cost. In addition, deviation of the resin composition can be prevented, and a semiconductor device with stable quality can be provided.
- the present invention also relates to a thermosetting resin sheet for use in a method for manufacturing a semiconductor device including a step (A) of collectively sealing a plurality of electronic components arranged on a support plate.
- thermosetting resin sheet The thermosetting resin sheet of the present invention will be described.
- the thermosetting resin sheet has a minimum viscosity of 30 Pa ⁇ s or higher, preferably 100 Pa ⁇ s or higher, in a temperature rise measurement using a viscoelastic spectrometer. Since it is 30 Pa ⁇ s or more, the flow of the resin at the time of sealing can be suppressed, and the protrusion of the resin to the outside of the sealing area can be prevented.
- the minimum viscosity is 3000 Pa ⁇ s or less, preferably 2000 Pa ⁇ s or less. Since it is 3000 Pa ⁇ s or less, good embeddability can be obtained, gaps between a plurality of electronic components arranged on the support plate can be filled well, and at the same time, chip displacement during sealing is prevented. it can.
- the minimum viscosity in the temperature rise measurement using a viscoelastic spectrometer can be measured by the method described in the Examples.
- the minimum viscosity in the temperature rise measurement using a viscoelastic spectrometer can be controlled by the content of the silica filler.
- the minimum viscosity can be increased by increasing the content of silica filler.
- the temperature showing the lowest viscosity is preferably 80 ° C. or higher, more preferably 90 ° C. or higher. When the temperature is 80 ° C. or higher, the handling property of the thermosetting resin sheet is good, and air entrapment during molding can be prevented.
