Abstract: PURPOSE:To prevent a solder bump from being re-melting by previously forming as an electrode on a surface a diffusion metal coated film which is likely to be diffused into solder with ease and which is raised in its melting temperature owing to its diffusion, and joinning the electrode with the solder bump. CONSTITUTION:A 2mum thick silver is deposited through plating on a substrate electrode 15, where a circuit is formed with 1mum thick copper previously formed on a substrate 14 by sputtering, through a metal which is likely to be diffused into solder and raises its melting point by diffusion, an 1mum thick nickel coated film in the present case, to yield a diffusion metal coated film 16. The diffusion metal coated film 16 and a solder bump 13 are matched in their positions on the substrate 14 heated at 220 deg.C from a substrate 14 lower substrate, and a semiconductor device 11 and the substrate 14 are joinned under pressure and held for about 30 seconds. Thereafter, the substrate is stopped in its heating and is cooled. With a series of the operations, the silver is diffused in the solder, and thereafter a melted solder bump 17 is not melted with the substrate heating at 220 deg.C.

Filed: 1988-10-21
Abstract: PURPOSE:To omit the calculation of a delay time every transmission path and the troublesome setting of a parameter at the time of generating a system by determining a time-out time based on a practically measured transmission delay time. CONSTITUTION:The transmission time of the final octet of transmitted information frames is stored into a storage part 3, and the reception time of the top octet of transmission confirming frames is stored into a storage part 6. The time difference between the reception time and the transmission time is calculated, based on the time difference, the time-out time is updated to the optimum value. That the transmitted frame arrives in the updated time-out time is supervised by a supervising means 9. Consequently, the difference of the transmission delay time due to the difference of network constitutions is corrected, the transmission efficiency by means of the time-out time fit for each network constitution is improved, the resetting of the time-out value at the time of switching a line to an alternate line at the time of a transmission path fault is made unnecessary, and the operation is facilitated. Thus, the troublesome calculation of the delay time at every transmission path and the parameter setting at the time of generating the system are obviated.
