Publication number: 20250201764Abstract: A joined body in which a first joining target (11) and a second joining target (13) are joined with a joining layer interposed therebetween is produced. A paste that contains copper particles and an organic solvent is applied to the first joining target (11) to form a coating film (12X). The second joining target (13) is placed on the coating film (12X) to form a stack (15). The stack (15) is heated and pressed to sinter the copper particles contained in the coating film (12X) to form a joining layer. The heating is performed incrementally from a heating start temperature to a highest temperature Tm, and the pressing is performed incrementally from a pressing start pressure to a highest pressure Pm, and control is performed in such a manner that a pressing pressure is 15 MPa or less when a heating temperature reaches 200° C.Type: ApplicationFiled: March 28, 2023Publication date: June 19, 2025Inventors: Takashi HATTORI, Shinichi YAMAUCHI, Kei ANAI
