  • Method of fabricating microelectromechanical system structures
    Patent number: 7405466
    Abstract: A method of simultaneously bonding components, comprising the following steps. At least first, second and third components are provided and comprise: at least one glass component; and at least one conductive or semiconductive material component. The order of stacking of the components is determined to establish interfaces between the adjacent components. A hydrogen-free amorphous film is applied to one of the component surfaces at each interface comprising an adjacent: glass component; and conductive or semiconductive component. A sol gel with or without alkaline ions film is applied to one of the component surfaces at each interface comprising an adjacent: conductive or semiconductive component; and conductive or semiconductive component. The components are simultaneously anodically bonded in the determined order of stacking.
    Type: Grant

  • Anodic bonding process for ceramics
    Patent number: 7115182
    Abstract: A method of bonding components comprising the following steps. At least a first ceramic component and a second ceramic component are provided. A first conductive layer is formed over the upper surface of the first ceramic component. An intermediate film is formed over the first conductive layer. A second conductive layer is formed over the lower surface of the second ceramic component. The second ceramic component is stacked over the first ceramic component wherein the second conductive layer on the second ceramic component opposes the intermediate film on the first component. The first and second ceramic components are anodically bonded together.
