    摘要： The generation of surface patterns or the replication of surface patterns is achieved in the present disclosure without the need to employ an etching process. Instead, a unique fracture mode referred to as spalling is used in the present disclosure to generate or replicate surface patterns. In the case of surface pattern generation, a surface pattern is provided in a stressor layer and then spalling is performed. In the case of surface pattern replication, a surface pattern is formed within or on a surface of a base substrate, and then a stressor layer is applied. After applying the stressor layer, spalling is performed. Generation or replication of surface patterns utilizing spalling provides a low cost means for generation or replication of surface patterns.

    摘要： A germanium-containing layer is deposited on a single crystalline bulk silicon substrate in an ambient including a level of oxygen partial pressure sufficient to incorporate 1%-50% of oxygen in atomic concentration. The thickness of the germanium-containing layer is preferably limited to maintain some degree of epitaxial alignment with the underlying silicon substrate. Optionally, a graded germanium-containing layer can be grown on, or replace, the germanium-containing layer. An at least partially crystalline silicon layer is subsequently deposited on the germanium-containing layer. A handle substrate is bonded to the at least partially crystalline silicon layer. The assembly of the bulk silicon substrate, the germanium-containing layer, the at least partially crystalline silicon layer, and the handle substrate is cleaved within the germanium-containing layer to provide a composite substrate including the handle substrate and the at least partially crystalline silicon layer. Any remaining germanium-containing layer on the composite substrate is removed.
