摘要:
A bonding structure with a buffer layer, and a method of forming the same are provided. The bonding structure comprises a first substrate with metal pads thereon, a protection layer covered on the surface of the substrate, a first adhesive metal layer formed on the metal pads, a buffer layer coated on the protection layer and the metal pads, a first metal layer covered on the buffer layer, and a second substrate with electrodes and a bonding layer thereon. The first metal layer, the electrodes and the bonding layer are bonded to form the bonding structure. Direct bonding can be performed through surface activation or heat pressure. The method uses fewer steps and is more reliable. The temperature required for bonding the structure is lower. The bonding density between the contacted surfaces is increased to a fine pitch. The quality at the bonding points is increased because fewer contaminations between the contacted surfaces are generated.

A perovskite-based thin film structure includes a semiconductor substrate layer, such as a crystalline silicon layer, having a top surface cut at an angle to the (001) crystal plane of the crystalline silicon. A perovskite seed layer is epitaxially grown on the top surface of the substrate layer. An overlayer of perovskite material is epitaxially grown above the seed layer. In some embodiments the perovskite overlayer is a piezoelectric layer grown to a thickness of at least 0.5 μm and having a substantially pure perovskite crystal structure, preferably substantially free of pyrochlore phase, resulting in large improvements in piezoelectric characteristics as compared to conventional thin film piezoelectric materials.

The present invention intends to provide a diamond-coated silicon to be used in an industrially applicable diamond electrode. A diamond-coated silicon comprising a silicon substrate having a thickness of 500 μm or less is coated at least partially with electrically conductive diamond. The silicon substrate having a thickness of 500 μm or less is manufactured by the plate-like crystal growth process, and then the silicon substrate is coated with the electrically conductive diamond by the chemical vapor deposition process to manufacture the diamond-coated silicon. The diamond-coated silicon is flexible and can be stuck to an electrically conductive support substrate, and thereby a large area electrode and a three-dimensional electrode structure can be readily obtained.

A method for inhibiting diffusion of silicon into a support structure from a component formed of a silicon-containing material, and an assembly formed thereby. The component is supported and contacted by the support structure so as to define a contact interface therebetween. An barrier coating is present on the component and/or the support structure, so as to be disposed at the contact interface to prevent direct physical contact between the silicon-containing material and the superalloy substrate.

Methods are disclosed for making a compound of nickel and silicon. According to an embodiment, on a surface of a substrate (e.g., silicon), multiple layer pairs are formed in a superposed manner. Each layer pair includes a respective layer of nickel and a respective layer of silicon each being 3 nm or less in thickness. The layers of nickel and silicon in the multiple layer pairs are formed in alternating order, thereby forming a multilayer structure, wherein the layers of nickel and silicon in the multilayer structure are formed at respective thicknesses corresponding to desired mole fractions of nickel and silicon in the multilayer structure. The multilayer structure is annealed at a temperature of 200° C. or less to form an amorphous alloy of nickel and silicon in the multilayer structure, wherein the alloy has the desired mole fractions of nickel and silicon. The amorphous alloy is allowed to nucleate and form a corresponding crystalline alloy having the desired mole fractions of nickel and silicon.
