Title: Method and structure for flip-chip connection and electronic device employing it
Inventor: ISADA NAOYA
IPC: H01L21/60
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To suppress fluctuation in connection resistance by thermally softening an insulation layer formed on a circuit board and deforming an electrode formed on the circuit board along with the softened insulation layer by applying a pressure thereby suppressing fluctuation in the height of the protruding electrodes of a semiconductor integrated circuit element. SOLUTION: A semiconductor integrated circuit element 1 is mounted on a tray coated uniformly with a conductive paste 3 composed of conductive particles 4 and a thermosetting resin and the conductive paste 3 is transferred to the forward end of protruding electrodes 2 of the semiconductor integrated circuit element 1. Subsequently, the element 1 is mounted such that a desired protruding electrode 2 is located at the electrode 7 of an organic circuit board 6 coated with a filling resin 9. Subsequently, the board 6 mounting the element 1 is heated, while being pressed, at a temperature close to the setting point of the resin 9 and held as it is until a sufficient adhesion takes place in the resin 9. Consequently, the insulation resin 8 of the board 6 is thermally softened to cause deformation of the electrode 7 and the resin 8.  Thereafter, positional relationship between the element 1 and the board 6 is sustained through setting of the resin 9 under a hot press state.

Filed: 1983-10-31
Abstract: PURPOSE:To increase the safety and the reliability of a fuel cell by increasing the airtightness between the edge seal area of a rib electrode and a separator so as to prevent the mixing of a fluid fuel with fluid oxidant which might result in heat generation or the deterioration of the characteristics of the fuel cell by packing a heat-resistant acid-proof resin between the edge seal area and the separator. CONSTITUTION:In each unit cell, a fluorine resin 4 used as a heat-resistant acid-proof resin is packed between the edge seal area of a rib electrode 2 and a separator 3. Owing to the above constitution, concave and convex areas existing in the surface of the edge seal area of the rib electrode 2 are absorbed and the close contact between the edge seal area and the separator 3 is achieved thereby increasing the airtightness between them. Accordingly a fluid fuel (B) is prevented from being mixed with a fluid oxidant (C) by preventing any development of gas leakage, thereby preventing any heat generation in a fuel cell stack and any deterioration of the characteristics of a fuel cell which might result from the mixing of the fluid fuel (B) with the fluid oxidant (C). Consequently, it is possible to obtain a fuel cell of high safety and reliability.
