摘要： A method of forming a strained semiconductor material that in one embodiment includes forming a cleave layer in a host semiconductor substrate, and contacting a strain inducing material layer on a surface of a transfer portion of the host semiconductor substrate. A handle substrate is then contacted to an exposed surface of the stress inducing material layer. The transfer portion of the host semiconductor substrate may then be separated from the host semiconductor substrate along the cleave layer. A dielectric layer is formed directly on the transfer portion of the host semiconductor substrate. The handle substrate and the stress inducing material are then removed, wherein the transferred portion of the host semiconductor substrate provides a strained semiconductor layer that is in direct contact with a dielectric layer.

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 stressor layer used in a controlled spalling method is removed through the use of a cleave layer that can be fractured or dissolved. The cleave layer is formed between a host semiconductor substrate and the metal stressor layer. A controlled spalling process separates a relatively thin residual host substrate layer from the host substrate. Following attachment of a handle substrate to the residual substrate layer or other layers subsequently formed thereon, the cleave layer is dissolved or otherwise compromised to facilitate removal of the stressor layer. Such removal allows the fabrication of a bifacial solar cell.

摘要： A stressor layer is formed atop a base substrate at a first temperature which induces a first tensile stress in the base substrate that is below a fracture toughness of base substrate. The base substrate and the stressor layer are then brought to a second temperature which is less than the first temperature. The second temperature induces a second tensile stress in the stressor layer which is greater than the first tensile stress and which is sufficient to allow for spalling mode fracture to occur within the base substrate. The base substrate is spalled at the second temperature to form a spalled material layer. Spalling occurs at a fracture depth which is dependent upon the fracture toughness of the base substrate, stress level within the base substrate, and the second tensile stress of the stressor layer induced at the second temperature.

摘要： An embedded, strained epitaxial semiconductor material, i.e., an embedded stressor element, is formed at the footprint of at least one pre-fabricated field effect transistor that includes at least a patterned gate stack, a source region and a drain region. As a result, the metastability of the embedded, strained epitaxial semiconductor material is preserved and implant and anneal based relaxation mechanisms are avoided since the implants and anneals are performed prior to forming the embedded, strained epitaxial semiconductor material.

摘要： A method of controlled layer transfer is provided. The method includes providing a stressor layer to a base substrate. The stressor layer has a stressor layer portion located atop an upper surface of the base substrate and a self-pinning stressor layer portion located adjacent each sidewall edge of the base substrate. A spalling inhibitor is then applied atop the stressor layer portion of the base substrate, and thereafter the self-pinning stressor layer portion of the stressor layer is decoupled from the stressor layer portion. A portion of the base substrate that is located beneath the stressor layer portion is then spalled from the original base substrate. The spalling includes displacing the spalling inhibitor from atop the stressor layer portion. After spalling, the stressor layer portion is removed from atop a spalled portion of the base substrate.
