Abstract: An apparatus and method determine a size of a bonding film for bonding a bonding target having a size which varies due to temperature variation, at an environmental temperature which is different from a temperature during use. The method includes measuring an actual size of the bonding portion of the circuit electrode at the first temperature, comparing the actual size of the bonding portion with a designed size of the bonding portion at the first temperature, and determining a cutting size of the bonding material based on a comparison result and mounting the bonding material over the bonding portion.

The method includes the steps of: measuring an actual size of the bonding portion of the circuit electrode at the first temperature; comparing the actual size of the bonding portion with a designed size of the bonding portion at the first temperature; and determining a cutting size of the bonding material based on a comparison result and mounting the bonding material over the bonding portion.

Abstract: A semiconductor assembling method joins a bonding wire with a bonding object by pressing the bonding wire against the bonding object with a bonding pressurizing tool and by effecting at least one junction process of thermal junction or ultrasonic junction. The method includes steps of measuring a time elapsing from a last bonding process to a subsequent bonding process or a temperature of the pressurizing tool, and changing at least one junction condition of pressurizing force, pressurizing time, ultrasonic oscillation output, and ultrasonic oscillation time for the subsequent bonding process, based on the measured time. A semiconductor assembling apparatus includes a measuring device for measuring the time or temperature and a junction condition changing device for changing the condition to perform the method.
