The sub-pad assembly includes an upper level metal line structure abutting the metal pad, a lower level metal line structure located underneath the upper level metal line structure, and a set of metal vias that provide electrical connection between the lower level metal line structure located underneath the upper level metal line structure.

摘要: An apparatus and method for utilizing NIR spectrography for measuring major constituents of substances in real time includes a monochromator or other sensor having no moving optical parts. At least one of the monochromator and the substance are moving relative to one another. An NIR radiation source irradiates a substance and the reflected or passed-through radiation is transmitted to the monochromator, which isolates and detects narrow portions of the received spectrum. By analyzing the intensities and wavelengths of the received radiation, the presence and amount of major constituents of the substance can be determined.

摘要: Unpinned epitaxial metal-oxide-compound semiconductor structures are disclosed and a method of fabricating such structures is described. Epitaxial layers of compound semiconductor are grown by MBE which result in the formation of a smooth surface having a stabilized reconstruction. An elemental semiconductor layer is deposited epitaxially in-situ with the compound semiconductor layer which unpins the surface Fermi level. A layer of insulator material is then deposited on the elemental semiconductor layer by PECVD. In one embodiment, the compound semiconductor is GaAs and the elemental semiconductor is Si. The insulator material is a layer of high quality SiO.sub.2. A metal gate is deposited on the SiO.sub.2 layer to form an MOS device. The epitaxial GaAs layer has a density of states which permits the interface Fermi level to be moved through the entire forbidden energy gap. In another embodiment, the SiO.sub.2 deposition completely consumes the interface Si layer so that the resulting MOS device comprises SiO.sub.2 directly overlying the GaAs layer.

摘要: In a semiconductor device, a contact with low resistance to a III-V compound semiconductor substrate was fabricated using refractory materials and small amounts of indium as the contact material. The contact material was formed by depositing Mo, Ge and W with small amounts of In onto doped GaAs wafers. The contact resistance less than 1.0 ohm millimeter was obtained after annealing at 800.degree. C. and the resistance did not increase after subsequent prolonged annealing at 400.degree. C.
