Title: Production of fibrous potassium titanate
Inventor: FUJIKI YOSHINORI
IPC: C01G23/00
Filed: 1981-10-16
Abstract: PURPOSE:A starting mixture consisting of K2O and TiO2 is subjected to dissociation and association reactions at a specific temperature to produce fibrous potassium titanate by no use of a flux at low costs. CONSTITUTION:A starting mixture consisting of TiO2 and K2O, which can be represented by a general formula of K2O.nTiO2 (where n=3-5) is heated and kept at 950-1,300 deg.C for 1-10hr to form a mixture of solid phase and liquid phase of K2Ti6O13. Then, the mixture is gradually cooled at a rate of at least lower than 70 deg.C/hour down to 900-950 deg.C to effect the association reaction of the K2Ti4O9 liquid phase-solid phase mixed composition. During the gradual cooling, the fiber of K2Ti4O9 grows long. After the gradual cooling, further cooling is continued gradually down to room temperature until the liquid phase solidifies to give K2TiO9 fiber or an agromerate thereof with K2Ti2O5 or K2Ti6O13. The product is dipped in warm water to separate fiber and calcined to give an insulating material or treated with an acid to leach out K ion and give an ion adsorbent.

Abstract: PURPOSE:To reduce the generation of a crack in a resin sealing part due to a stress and to contrive the improvement of the reliability of a semiconductor device by a method wherein recessed parts are provided in the surface of the resin sealing part on the side of the rear of a die pad. CONSTITUTION:A semiconductor device is manufactured into a structure, wherein a semiconductor pellet 1 is mounted on a die pad 2 and these of the pad 2 and the pellet 1 are respectively sealed by a resin sealing part 3. However, at the time of a high-temperature treatment at the time of packaging of the device, a crack is generated in the sealing part 3 due to a stress, which is generated by vaporization of water content in the interface between the pad 2 and the sealing part 3. In order to prevent the generation of the defect, recessed parts 5 are provided in the surface of the sealing part 3 on the side of the rear of the pad 2. Thereby, as the stress, which is generated by the vaporization of water content in the interface between the pad 2 and the sealing part 3, is dispersed by the recessed parts 5, the generation of the crack in the sealing part 3 due to the stress can be less reduced and the reliability of the semiconductor device can be improved.
