    Abstract: Provided are a method for producing a phosphorus-containing phenolic compound in which reactivity is considerably excellent in the reaction between a phosphorus-containing compound and an aromatic nucleus of a phenol; in the case of using a polyhydric phenol or a phenolic resin as the phenol, a novel phosphorus-containing phenolic compound that serves as a curing agent for an epoxy resin and imparts excellent heat resistance to a cured product; a curable resin composition containing the novel phosphorus-containing phenolic compound; a cured product of the curable resin composition; a printed wiring board; and a semiconductor sealing material. An aromatic aldehyde (a1) having an alkoxy group as a substituent on an aromatic nucleus is allowed to react with an organic phosphorus compound (a2) intramolecularly having a P—H group or a P—OH group. The resultant reaction product is then allowed to react with a phenol (a3).

  • Patent number: 8268673
    Abstract: A stacked electronic component comprises a first electronic component adhered on a substrate via a first adhesive layer, and a second electronic component adhered by using a second adhesive layer thereon. The second adhesive layer has a two-layer structure formed by a same material and having different modulus of elasticity. The second adhesive layer of the two-layer structure has a first layer disposed at the first electronic component side and a second layer disposed at the second electronic component side. The first layer softens or melts at an adhesive temperature. The second layer maintains a layered shape at the adhesive temperature. According to the stacked electronic component, occurrences of an insulation failure and a short circuiting are prevented, and in addition, a peeling failure between the electronic components, an increase of a manufacturing cost, and so on, can be suppressed.
