METHOD OF MAKING A CONTROLLED SEAM LAMINATED MAGNETIC CORE FOR HIGH FREQUENCY ON-CHIP POWER INDUCTORS |
摘要 |
A controlled seam magnetic core lamination utilizable in an inductor structure includes a magnetic base and first and second spaced-apart magnetic sidewalls extending substantially orthogonally from the base to define a seam therebetween. The controlled seam magnetic core lamination is utilizable in an inductor structure that includes: a non-conductive lower mold; a plurality of spaced-apart controlled seam lower laminations formed in the lower mold, each magnetic lower lamination having a horizontal base and first and second spaced-apart sidewalls extending substantially vertically upward from the base to define a seam therebetween; a non-conductive isolation layer formed on the lower mold and the magnetic lower laminations; a conductive trace formed on the isolation layer; a non-conductive upper mold formed over the isolation layer and the conductive trace; and a plurality of spaced-apart controlled seam magnetic upper laminations formed in the upper mold, each magnetic upper lamination having a horizontal base and first and second spaced-apart sidewalls that extend substantially vertically upward from the base to define a seam therebetween.
