摘要:
Various embodiments provide semiconductor devices having cavity substrate structures for package-on-package assembly and methods for their fabrication. In one embodiment, the cavity substrate structure can include at least one top interconnect via formed within a top substrate. The top substrate can be disposed over a base substrate having at least one base interconnect via that is not aligned with the top interconnect via. Semiconductor dies can be assembled in an open cavity of the top substrate and attached to a base center portion of the base substrate of the cavity substrate structure. A top semiconductor package can be mounted over the top substrate of the cavity substrate structure.

In the searchable encryption processing system, a data base server retaining data, a registration client which deposits the data into the data base server, and a search client which causes the data base server to search the data collaborate across a network, wherein the registration client, using a probabilistic encryption method which uses a mask using a homomorphic function and a hash value, deposits the encrypted data into the server, whereupon the search client, using probabilistic encryption which uses the mask which uses the homomorphic function for encryption of the search query, outputs the search query and non-corresponding data as search results without causing the data base server to unmask the mask and without allowing the frequency of occurrences of the data corresponding to the search to leak to the data base server.
