1. An electronic device enclosure, comprising:
- a unitary ceramic cover formed from a sapphire material, comprising;
a top surface;
a bottom surface; and
a blind recess formed into the bottom surface and extending toward the top surface, the blind recess defined by a recessed surface and interior sidewalls extending from the recessed surface to a bottom surface of the unitary ceramic cover;
a peripheral structure overmolded over a portion of the unitary ceramic cover and into the blind recess and that defines an attachment member secured within the blind recess along the interior sidewalls and the recessed surface; and
an outer housing member coupled with the peripheral structure opposite the unitary ceramic cover, whereina thickness of the unitary ceramic cover is less than 5 millimeters.

Abstract
An electronic device having an enclosure formed from at least one ceramic cover and a peripheral structure adjacent the periphery of the ceramic cover is disclosed. The peripheral structure can be secured adjacent to the ceramic cover with an attachment member. The ceramic cover can include a recess to receive the attachment member. The peripheral structure can be molded adjacent the ceramic cover so that a gapless interface can be formed between the peripheral structure and the periphery of the ceramic cover.
