Title: Fabricating method of semiconductor device
Inventor: KAJIWARA KOUSEI
IPC: H01L21/52
Filed: 1978-11-20
Abstract: PURPOSE: To reduce the contact resistance of a die bond in a semiconductor device by implanting irradiately ion containing impurity having the same conductivity as a chip substrate on the bonded surface of a silicon chip.  
     CONSTITUTION: When a wafer exposed at its high resistance surface from the previous process is die bonded, ion such as boron or the like is implanted on the back surface 9 polished of a wafer 8 to thereby form an implanted layer 10. Then a semiconductor pellet 11 is then placed on a metallic layer header 12 without annealing process and die bonded at approx. 450°. Thus, the semiconductor pellet and the header are pressed and heated to cause both the back surface 9 of the pellet and the Au plated layer 13 of the header become in Au-Si eutectic molten state. Then, boron is molten into the Au-Si eutectic portion, but segregation occurs at cooling step upon completion of the die bonding process to cause occurrence of a degenerated layer by the boron is the vicinity of the back surface of the pellet at recrystallized layer so as to thus improve the ohmic property of the boundary thereat.
