发明名称 METHODS OF LASER SURFACE MODIFICATION OF CERAMIC PACKAGES FOR UNDERFILL SPREAD CONTROL AND STRUCTURES FORMED THEREBY
摘要 Methods and associated structures of forming a microelectronic device are described. Those methods may include heating a portion of a ceramic substrate adjacent to a C 4 area with a defocused laser, wherein a smooth region of the substrate is created, and applying an underfill material to the C 4 area, wherein the underfill material does not extend past the smooth region.
