Abstract
A single-lid flash memory card and methods of manufacturing same are disclosed. The single-sided lid flash memory card may be formed from a semiconductor package having two or more tapered, stepped or otherwise shaped edges capable of securing a single-sided lid thereon. The taper, step or other shape may be fabricated by various methods, including during the molding step or during the singulation step. A semiconductor package having shaped edges may be enclosed within an external lid to form a finished flash memory card. The lid may be applied to a single side of the semiconductor package by various processes, including over-molding, or by pre-forming the lid with interior edges to match the exterior edges of the semiconductor package, and then sliding the lid over the package to form a tight fit therebetween. The shaped edge of the semiconductor package effectively holds the lid securely on the memory card without any adhesives and prevents the lid from dislodging from the semiconductor package.
