  • Publication number: 20170084628
    Abstract: Substrate-transferred, deep trench isolation silicon-on-insulator (SOI) semiconductor devices formed from bulk semiconductor wafers are disclosed. In this regard, a bulk semiconductor wafer is provided that includes a bulk body, one or more transistors formed in the bulk body, and deep trenches formed between the transistors formed in the bulk body to provide isolation between the transistors. To prevent the bulk body from electrically interconnecting the transistors, the bulk body is thinned near, at, or beyond a back side of the deep trenches formed in the bulk body to form separate bulk bodies for each transistor isolated by the deep trenches. An insulation substrate is bonded to the bulk semiconductor device to form an SOI wafer. In this manner, residual bulk bodies of the transistors in the SOI wafer are isolated between the deep trenches and the insulation substrate to reduce or avoid leakage current between transistors.

  • Publication number: 20160293477
    Abstract: Silicon-on-insulator (SOI) wafers employing molded substrates to improve insulation and reduce current leakage are provided. In one aspect, a SOI wafer comprises a substrate. An insulating layer (e.g., a buried oxide (BOX) layer) is disposed above the substrate to insulate an active semiconductor layer disposed above the insulating layer, from the substrate. Transistors are formed in the active semiconductor layer. To provide for improved insulation between the active semiconductor layer and the substrate to reduce leakage and improve performance of the active semiconductor layer, the substrate is provided in the form of a molded substrate. A coating layer is also disposed between the molded substrate and the insulating layer of the SOI wafer, in case, for example, the melting temperature of a molding compound used to form the molded substrate is not low enough to prevent contamination of the active semiconductor layer into the insulating layer.
