Claim 20:
21. An apparatus, comprising:
first and second substrates, each comprising
a base configured to support a stack; and
at least one peripheral wall extending from the base,

wherein one of the first or second substrates comprises a well defined within the at least one peripheral wall so that adhesive is contained within the well and does not leak outside of the at least one peripheral wall, and wherein the well comprises (1) a first portion that has a bottom surface that intersects a first plane parallel to the base, and (2) a second portion that has a bottom surface that intersects a second plane parallel to the base, where the first plane is closer to the base than the second plane,
wherein the first and second substrates are mechanically anchored at the well by the adhesive,
wherein the at least one peripheral wall of the first and second substrates laterally extend around the stack to form an enclosure,
wherein the first portion is configured to contain a predetermined amount of adhesive, and
wherein the second portion is configured to contain overflow of the adhesive within the well when the first and second substrates are mechanically anchored.
