摘要: A manufacturable GaAs VFET process includes providing a doped GaAs substrate with a lightly doped first epitaxial layer thereon and a heavily doped second epitaxial layer positioned on the first epitaxial layer. A temperature tolerant conductive layer is positioned on the second epitaxial layer and patterned to define a plurality of elongated, spaced apart source areas. Using the patterned conductive layer, a plurality of gate trenches are etched into the first epitaxial layer adjacent the source areas. The bottoms of the gate trenches are implanted and activated to form gate areas. A gate contact is deposited in communication with the implanted gate areas, a source contact is deposited in communication with the patterned conductive layer overlying the source areas, and a drain contact is deposited on the rear surface of the substrate.

摘要: Concepts and methods are provided to reduce the cost and complexity of thin film battery (TFB) high volume manufacturing by eliminating and/or minimizing the use of conventional physical (shadow) masks. Laser scribing and other alternative physical maskless patterning techniques meet certain or all of the patterning requirements. In one embodiment, a method of manufacturing thin film batteries comprises providing a substrate, depositing layers corresponding to a thin film battery structure on the substrate, the layers including, in order of deposition, a cathode, an electrolyte and an anode, wherein at least one of the deposited layers is unpatterned by a physical mask during deposition, depositing a protective coating, and scribing the layers and the protective coating. Further, the edges of the layers may be covered by an encapsulation layer. Furthermore, the layers may be deposited on two substrates and then laminated to form the thin film battery.

摘要: High quality epitaxial layers of compound semiconductor materials can be grown overlying large silicon wafers by first growing an accommodating buffer layer on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer.
