摘要:
A method for fabricating a semiconductor device includes providing a die with a metallization layer including a first metal with a high melting point; providing a die carrier including a second metal with a high melting point; providing a solder material including a third metal with a low melting point; providing a layer of a fourth metal with a high melting point on the semiconductor die or the die carrier; and soldering the semiconductor die to the die carrier and creating: a first intermetallic compound between the semiconductor die and the die carrier and including the first metal and the third metal; a second intermetallic compound between the first intermetallic compound and the die carrier and including the second metal and the third metal; and precipitates of a third intermetallic compound between the first intermetallic compound and the second intermetallic compound and including the third metal and the fourth metal.
