Abstract
An encapsulation for a device is disclosed. Spacer particles are randomly located in the device region to prevent a cap mounted on the substrate from contacting the active components, thereby protecting them from damage. The spacer particles comprise a base and an upper portion, the base being at least equal to or wider than the upper portion, for preventing the generation of dark spots around the spacer particles.
