Abstract: A package packaged with a cap. The package features trenches, through holes, and a non-conductive coupling element forming a locking mechanism integrated embedded or integrated within a substrate. The package has a cap coupled to the non-conductive coupling element through ultrasonic plastic welding. The package protects the dice from an outside environment or external stresses or both. A method is desired to form package to reduce glue overflow defects in the package. Fabrication of the package comprises drilling holes in a substrate; forming trenches in the substrate; forming a non-conductive coupling element in the through holes and the trenches to form a locking mechanism; allowing the non-conductive coupling element to harden and cure; coupling a die or dice to the substrate; and coupling a cap to the non-conductive coupling element to protect the die or dice from an outside environment or external stresses or both.
