Claims
- 1. A structure having: a component formed from a single phase alloy consisting essentially of from about 30% to about 60% nickel, from about 0.001% to about 0.15% nitrogen, at least one element selected from the group of from about 1% to about 10% molybdenum and from about 0.001% to about 2% aluminum, and the balance essentially iron.
- 2. The structure of claim 1 further comprising:
- at least one aluminum or aluminum alloy component bonded to said iron-nickel alloy component.
- 3. The structure of claim 1 further comprising:
- at least one layer of non-metallic material bonded to said iron-nickel alloy component.
- 4. The structure of claim 3 wherein said non-metallic material comprises a glass material.
- 5. The structure of claim 2 wherein:
- said structure comprises a semiconductor package;
- said iron-nickel alloy component comprises at least one lead of a lead frame; and
- said at least one aluminum or aluminum alloy component comprises at least one lead wire.
- 6. The structure of claim 5 further comprising:
- said lead frame being entirely formed from said alloy.
- 7. The structure of claim 6 further comprising:
- each said lead wire being formed from a silicon containing aluminum alloy.
- 8. The structure of claim 5 further comprising:
- a semiconductor device; and
- each said lead being connected to said device by at least one lead wire.
- 9. The structure of claim 6 further comprising:
- at least one layer of a glass sealing material bonded to said iron-nickel alloy lead frame.
- 10. The structure of claim 9 further comprising:
- at least one component formed from a ceramic material, said iron-nickel alloy lead frame being bonded to said at least one ceramic material component by said at least one glass sealing material layer so as to form a hermetic package.
- 11. The structure of claim 1 having a component formed from an alloy consisting essentially of from about 39% to about 55% nickel, from about 0.005% to about 0.05% nitrogen, at least one element selected from the group consisting of about 1% to about 4% molybdenum, about 0.3% to about 1.0% aluminum or combinations thereof, and the balance essentially iron.
- 12. The structure of claim 1 having a component formed from a chromium free alloy consisting essentially of from about 30% to about 60% nickel, from about 0.00% to about 0.15% nitrogen, at least one element selected from the group consisting of from about 1% to about 10% molybdenum and from about 0.001% to about 2% aluminum, and the balance essentially iron.
- 13. The structure of claim 12 having a component formed from a chromium free alloy consisting essentially of from about 39% to about 55% nickel, from about 0.005% to about 0.05% nitrogen, at least one element selected from the group consisting of about 1% to about 4% molybdenum, about 0.3% to about 1.0% aluminum or combinations thereof, and the balance essentially iron.
