    摘要: A method of forming a metal or metal nitride layer interface between a copper layer and a silicon nitride layer can include providing a metal organic gas or metal/metal nitride precursor over a copper layer, forming a metal or metal nitride layer from reactions between the metal organic gas or metal/metal nitride precursor and the copper layer, and depositing a silicon nitride layer over the metal or metal nitride layer and copper layer. The metal or metal nitride layer can provide a better interface adhesion between the silicon nitride layer and the copper layer. The metal layer can improve the interface between the copper layer and the silicon nitride layer, improving electromigration reliability and, thus, integrated circuit device performance.

    摘要: A diode is formed at the tip of a pointed portion of a probe of a scanning probe microscope. When the diode is forward biased, the current through the diode varies with the temperature of the diode. The magnitude of the current is an indication of the temperature of the tip of the probe. If the tip is scanned over a surface, a thermal map of the surface can be made and hot spots on the surface located. In some embodiments, the pointed portion of the probe is made of a semiconductor material (for example, silicon). A layer of a metal (for example, platinum) is made to contact the semiconductor material of the pointed portion only at the tip of the pointed portion, thereby forming a very small temperature sensing Schottky diode at the tip of the pointed portion.

    摘要: An improved process is provided for forming a multilayer structure (18) suitable for tape automated bonding thereto or for forming contacts. In the process, a first layer (12) of aluminum is formed on a substrate (10), a second layer (14) of a TiW alloy is formed on the first layer of aluminum, and a third layer (16) of gold is formed on the second layer of the TiW alloy, to which third layer of gold bonding is done. The improvement comprises annealing the second layer of the TiW alloy in an inert atmosphere at a temperature less than about 500.degree. C. for a period of time sufficient to form a film of an Al--TiW phase (20), believed to comprise TiAl.sub.3, at the interface between the first layer of aluminum and the second layer of the TiW alloy. The annealing is done prior to forming the third layer of gold on the second layer of the TiW alloy.

    摘要: A method for measuring porosity of nanoporous materials is provided using atomic force microscopy (AFM). A surface topology map with sub-atomic resolution is created using AFM wherein the pore shape and size can be determined by measuring the pores that intersect the top or fracture surface. For porous materials requiring more accurate measurements, small scan areas with slow scan speed and fine AFM tips are used and a general estimation on distribution can be made from a sample area.
