Abstract
Semiconductor packages with multiple substrates can incorporate apertures or slots between devices to minimize or reduce formation of defects during a molding process. The apertures or slots can be formed adjacent a top substrate in alignment with removable regions adjacent a bottom substrate whereby the apertures or slots can facilitate outflow of materials from cavities between the substrates. The apertures or slots may subsequently be removed in conjunction with the removable regions during a singulation process thereby producing the desired semiconductor packages with improved device reliability and yield.
