摘要: In the existent method for manufacturing a solar cell, manufacture of a solar cell having a quantum well having a crystalline well layer and capable of controlling the thickness of the well layer was difficult. A quantum well having an amorphous well layer, comprising a barrier layer and an amorphous well layer is formed and then the quantum well having the amorphous well layer is annealed thereby crystallizing the amorphous well layer to form a quantum well having a crystalline well layer. By applying energy density applied to the amorphous well layer at an energy density of 1.26 J/mm2 or more and 28.8 J/mm2 or less, the crystalline well layer can be formed and the lamination structure of the quantum well can be maintained simultaneously.

摘要: In a conventional solar cell, it has been difficult to ensure a sufficient light absorption and simultaneously to prevent current loss due to the reduction of the moving distance of electrons and holes. As a means for solving this difficulty, a plurality of a p-i-n junctions are stacked through an insulating film and are connected in parallel with each other using through-electrodes. In this case, the through-electrodes and the p-i-n junctions are connected through the p-layer or the n-layer, thereby moving electrons and holes in opposite directions and generating output current. In addition, the i-layer is made thicker than the p-layer and the n-layer in each of the p-i-n junctions, thereby ensuring a sufficient light absorption and simultaneously preventing current loss.

摘要: A surface reflectivity of a solar cell is reduced by applying a nanopillar array including a plurality of nanopillars to the solar cell. Further, by constituting the nanopillars with a Si/SiGe superlattice and controlling a Ge composition ratio of a SiGe layer (2), excited electron and hole are spatially separated in different layers, thus increasing a carrier lifetime, and at the same time, an optical-electrical conversion efficiency is improved by a multi-exciton phenomenon due to a quantum confinement effect. In addition, by forming an intermediate band by thinning a Si layer (1) and the SiGe layer (2), a carrier extraction efficiency is improved.

摘要: When a bulk silicon substrate and an SOI substrate are used separately, a board area is increased and so it is impossible to reduce the size of a semiconductor device as a whole. On the other hand, when an SOI-type MISFET and a bulk-type MISFET are formed on a same substrate, the SOI-type MISFET and the bulk-type MISFET should be formed in separate steps respectively, and thus the process gets complicated. A single crystal semiconductor substrate and an SOI substrate separated from the single crystal semiconductor substrate by a thin buried insulating film and having a thin single crystal semiconductor thin film (SOI layer) are used, and well diffusion layer regions, drain regions, gate insulating films and gate electrodes of the SOI-type MISFET and the bulk-type MISFET are formed in same steps. Since the bulk-type MISFET and the SOI-type MISFET can be formed on the same substrate, the board area can be reduced. A simple process can be realized by making manufacturing steps of the SOI-type MISFET and the bulk-type MISFET common.
摘要翻译: 当单独使用体硅衬底和SOI衬底时,板面积增加,因此整体上不可能减小半导体器件的尺寸。 另一方面,当在同一衬底上形成SOI型MISFET和体型MISFET时,分别将SOI型MISFET和体型MISFET分别形成,因此工艺变得复杂。 使用通过薄埋入绝缘膜与单晶半导体衬底分离并具有薄单晶半导体薄膜(SOI层)的单晶半导体衬底和SOI衬底,以及良好扩散层区域,漏极区域,栅极绝缘膜 并且以相同的步骤形成SOI型MISFET和体型MISFET的栅电极。 由于可以在同一基板上形成体型MISFET和SOI型MISFET,所以可以减小电路板面积。 可以通过制造SOI型MISFET和体型MISFET的制造步骤来实现简单的工艺。

摘要: A CMOS circuit in low-voltage implementation, low power-consumption implementation, high-speed implementation, or small-size implementation. In a circuit which uses a FD-SOI MOST where a back gate is controlled by a well, voltage amplitude at the well is made larger than input-voltage amplitude at the gate. Alternatively, the circuit is modified into a circuit which uses a MOST that changes dynamically into an enhancement mode and a depletion mode.
