Patent JP-H047863-A (JP)
Title: Lead frame material for semiconductor
Inventor: OZAKI RYOICHI
IPC: H01L23/50
Filed: 1990-04-25
Abstract: PURPOSE:To facilitate highly reliable wire bonding by forming a Cu layer and a Cu-Ag alloy layer on the surface of a copper or copper alloy based lead frame. CONSTITUTION:A pure Cu layer of 0.5mum or more in thickness is formed on the surface of copper or copper alloy based lead frame material. A Cu-Ag alloy layer of 0.01mum or more in thickness is formed on the uppermost layer. Thereby, in the case of heating in a reactive atmosphere into which O2 is mixed, oxidation can be restrained for a long time, so that partial Ag plating on the die and the wire bonding part of a lead frame is not necessary. Hence the die and the wire can be directly bonded to copper alloy even in the field of an IC.

Filed: 1984-05-31
Abstract: PURPOSE:To improve the efficiency of analysis by providing a means for storing information signals and scanning position signals obtained from the sample and performing scanning in a spiral form from the most important point on the sample surface. CONSTITUTION:An X-ray beam 6 discharged from an excitation source 8 is irradiated upon a sample 1, and then characteristic X-rays 7 discharged from the sample 1 are detected by a detector 9 such as a proportional counter before the result of the detection is supplied to a memory 5. A sample base 2 on which the sample 1 is placed is moved in the X and the Y directions by means of drivers 3 and 4 to move the point, upon which the X-ray beam 6 becomes incident, in a spiral form and the signal indicating the position of the above point is supplied to a memory 5. The signal from the detector 9 is stored in the unit memory element of the memory 5 for storing the position determined by the positional signal (x, y). And, the content of the memory 5 is scanned and displayed by a television 10. Therfore, it is possible to preferentially analyze an arbitrary point on the sample surface and subsequently analyze peripheral points successively. Consequently, operation efficiency can be improved by eliminating useless analysis.
