Due to the recent performance improvement of IC chips in electronic devices such as PCs, servers, etc., the demand for flip-chip package substrate using build-up process has been increasing due to providing the benefits of higher speed and higher density.
SHINKO provides flip-chip package substrates, DLL®, which have the fine line patterning through the use of a semi additive process, multilayer structure, and excellent electrical characteristics and design flexibility through the use of stacked via structures.
Also, to meet the acceleration of high-density and high-speed of IC chips, the demand for flip-chip package substrates with high density, good electrical performance, and a thinner structure has been increasing. Therefore, SHINKO has developed the coreless package (DLL3®) which has thinner thickness structure coupled with good electrical performance and high design flexibility.
