摘要:
A first cell mass substantially containing only either one of mesenchymal cells or epithelial cells and a second cell mass substantially containing only the other one of the cells are positioned in contact with each other inside a support carrier which can maintain a condition of cell contact; and cultured to obtain a tooth having a specific cell placement. Preferably, after the culturing, the support carrier having both cell masses is cultured with kidney cells.

摘要:
A trench MOS type SiC semiconductor device includes a first conductivity semiconductor substrate, a first conductivity drift layer on the substrate, a second conductivity base layer on the drift layer, a first conductivity source layer on the base layer, a stripe shaped trench reaching from the surface of the source layer to the drift layer and having a gate electrode via a gate oxide film, a second conductivity layer on the bottom of the trench, and a second conductivity type region thereon on across-the-width side walls of at least one end of the trench, electrically coupling the second conductivity layer with the base layer. The device allows a low on-resistance without newly forming an electrode connected to the second conductivity layer even in the case of a device in which the second conductivity layer has to be grounded.
