    摘要: The present semiconductor device and method of fabrication thereof includes the provision of a trench or via hole in a dielectric, with a barrier layer thereon extending into the trench or via hole. A layer of titanium is provided over the barrier layer, also extending into the trench or via hole, and aluminum or aluminum alloy is provided over the titanium layer. The barrier layer provides good conformal coverage while also preventing outgassing of the dielectric from adversely affecting the conductor. The barrier layer also serves as a wetting agent for the deposition and flowing of aluminum or aluminum alloy. The titanium layer can be extremely thin, or non-existent, so as to avoid significant growth of TiAl.sub.3 and the problems attendant thereto.

    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.
