Abstract:
A method of doping a substrate. The method may include implanting a dose of a helium species into the substrate through a surface of the substrate at an implant temperature of 300°C or greater. The method may further include depositing a doping layer containing a dopant on the surface of the substrate, and annealing the substrate at an anneal temperature, the anneal temperature being greater than the implant temperature.
Abstract:
A method for manufacturing a vertical power semiconductor device is provided, wherein a first impurity is provided at the first main side (103) of a semiconductor wafer (101). A first oxide layer (112) is formed on the first main side (103) of the wafer (101), wherein the first oxide layer (112) is partially doped with a second impurity in such way that any first portion of the first oxide layer (112) which is doped with the second impurity is spaced away from the semiconductor wafer by a second portion of the first oxide layer (112) which is not doped with the second impurity and which is disposed between the first portion of the first oxide layer (112) and the first main side (103) of the semiconductor wafer (101). Thereafter a carrier wafer (115) is bonded to the first oxide layer (112). During front-end-of-line processing on the second main side (102) of the semiconductor wafer (101), the second impurity is diffused from the first oxide layer (112) into the semiconductor wafer (101) from its first main side (103) by heat generated during the front-end-of-line processing.
Abstract:
Structure d'accueil pour connecter électriquement un nano-objet sur une face de celle-ci et en reprendre le contact électrique sur la face opposée, et procédés de fabrication de la structure. L'invention, qui s'applique notamment à la caractérisation moléculaire, utilise un support (44) pour connecter un nano-objet (50) sur sa face supérieure et en reprendre le contact électrique sur sa face inférieure. Au moins deux interconnexions (52, 54) traversent le support. Les deux faces de celui-ci comprennent des zones de reprise de contact (56, 58, 60, 62) pour les interconnexions. Selon l'invention, au moins les zones (56, 58) de la face supérieure sont des zones dopées ayant chacune un motif adapté à l'épanouissement, sur cette face, de l'interconnexion associée.
Abstract:
Atomizer for atomizing a doping solution for treating a substrate therewith, wherein the atomizer comprises an atomizing element with a liquid compartment for receiving the doping solution to be atomized, wherein the atomizing element is an atomizing element functioning on the basis of an air flow. The invention further relates to a method for treating a substrate, wherein the method comprises the following steps: - providing a substrate; - atomizing a doping solution; - supplying the atomized doping solution to the substrate to treat the substrate therewith, wherein the doping solution is atomized by passing an air flow over the doping solution.
