In this paper, heights of bumps on the flip chip substrate in semiconductor package are inspected by using 3D inspection equipment. As a 3D inspection equipment, white light scanning interferometry with large FOV (Field Of View) is used. Experimental 3D data repeatability test results for the same flat bumps and round bumps of each substrate are shown. This paper is surely helpful for the development...
In the case of embedded chip type CSPs (Chip Scale Packages) made by embedding chips in PCBs (Printed Circuit Boards), problems occur due to differences in the CTE (Coefficient of Thermal Expansion) between the PCBs and the chips. This study tested a method to solve this problem by inserting thermal SBLs (Stress Absorbing Layers) into the embedded chips, thereby improving the reliability of the connection...
The practicalities when applying the ICH GCPs (International Conference on Harmonization 1996 Good Clinical Practices [EU, MHLW, FDA. International Conference on Harmonization Guideline for Good Clinical Practice; 1997] in less developed countries (ldcs) are seldom discussed and we found no guidelines as how to “adapt” them. Below we illustrate how ICH GCP principles can be implemented in different...
Living kidney transplantations constitute the majority of kidney transplantations in Korea. Recently, relay kidney transplantation, which is a modified form of both 'exchange transplantation' and 'living anonymous donation', has become at issue. After a living anonymous donor makes the initial donation, the next donor, who is related to the first recipient, makes the second donation; the third donor,...
The stabilities and transferabilities of monolayers for the two kinds of polyamic acid alkylamine salts (PAAS) were investigated. The stability of monolayer increases as the chain length of salts increases. At well-balanced condition, the Langmuir film is transferred as a Y-type on various substrates, and the thickness of one layer of PAAS was found to be about 16.7 Å,.
