Semiconductor encapsulant resin having an additive with a gradient concentration

   
   

Provided is an encapsulant resin for a semiconductor that effectively functions even with a relatively small amount of an additive. The encapsulant resin for a semiconductor is characterized in that the additive has a concentration gradient in the direction of thickness of the encapsulant resin. Specifically, the concentration gradient of the additive is established in the direction of thickness of the encapsulant resin by stacking at least two types of organic polymer resins containing different contents of the additive to form the encapsulant resin or by applying an electric field to the encapsulant resin to effect electrophoresis of the polar additive in the encapsulant resin.

Desde que é uma resina encapsulant para um semicondutor esse funciona eficazmente mesmo com um pouco relativamente de um aditivo. A resina encapsulant para um semicondutor é caracterizada que o aditivo tem um gradient da concentração no sentido da espessura da resina encapsulant. Especificamente, o gradient da concentração do aditivo é estabelecido no sentido da espessura da resina encapsulant empilhando ao menos dois tipos de resinas orgânicas do polímero que contêm índices diferentes do aditivo para dar forma à resina encapsulant ou aplicando um campo elétrico à resina encapsulant para efetuar o electrophoresis do aditivo polar na resina encapsulant.
