- H T O L refers to the life under conditions where the device is allowed to stand while operating under high temperature.
- a semiconductor device is a gold wire between the semiconductor element and the lead frame.
- Conductive connection In particular, on the lead frame side, the gold wire and the aluminum pad are joined together by heat and ultrasonic waves. At this time, gold and aluminum form an eutectic or alloy called intermetallic compound. When stored at high temperatures, this intermetallic compound grows, causing cracks and corrosion, which increases the connection resistance. On the other hand, when operating at high temperatures, the phenomenon occurs in an environment where the flow of electrons occurs due to the flow of real current, and the behavior will be different from that at high temperature storage without current flow. .

- the electrical migration can be suppressed by blending the aluminum element, once the electrical migration occurs, the strength of the joint portion decreases.
- the semiconductor device is exposed to high temperatures, stress is generated at the joint. If the stress at the joint exceeds the strength at the joint, the joint will peel off, that is, a bond drift will occur, increasing the connection resistance. Therefore, in order to improve H T O L, it is important to further reduce the stress in addition to greatly suppressing electrical migration.
