Abstract:
A silicon wafer supporting device, for the evaporation of the wafer backside, comprising a plate-like element (10); its particularity consists of the fact that it comprises at least one blind seat (11) which is formed at the lower surface of the plate-like element (10) and is adapted to accommodate at least one silicon wafer (2) whose lower side must be subjected to a metallization process, a plurality of bracket-like elements (12) being rigidly fixed to the plate-like element (10) and being adapted to support the at least one silicon wafer (2) at its perimeter.
Abstract:
An integrated vacuum microelectronic structure (1) is described which includes: a highly doped semiconductor substrate (11), a first insulating layer (12) placed above the doped semiconductor substrate (11), a first conductive layer placed above the first insulating layer, a second insulating layer (93) placed above the first conductive layer, a vacuum trench (19) formed within the first and second insulating layers (12, 93) and extending to the highly doped semiconductor substrate (11), a second conductive layer (42) placed above the vacuum trench and acting as a cathode, a third conductive layer (22) placed under the highly doped semiconductor substrate (11) and acting as an anode, the second conductive layer (42) is placed adjacent to the upper edge (40) of the vacuum trench (19), wherein the first conductive layer is separated from the vacuum trench (19) by portions of the second insulating layer and is in electrical contact with the second conductive layer (42). (Fig. 1).
