Abstract:
A relatively thin gate insulator of a digital switching transistor is formed from a layer of silicon oxynitride which was initially formed by implanting nitrogen atoms in a silicon substrate and oxidizing the nitrogen and silicon. It has been discovered that an outer layer of silicon dioxide is formed as a part of the silicon oxynitride layer. Removing this outer layer of silicon dioxide from the silicon oxynitride layer leaves a thin remaining layer of substantially-only silicon oxynitride as the gate insulator. Thinner gate insulators of approximately 15-21 angstroms, for example, can be formed from a grown thickness of 60 angstroms, for example. Gate insulators for digital and analog transistors may be formed simultaneously with a greater differential in thickness been possible by using conventional nitrogen implantation techniques.
Abstract:
A stackable solid-state battery cell, a packaged solid-state battery including the same, and a method of making the same are disclosed. The battery cell includes a substrate, a cathode on or over the substrate, a solid-state electrolyte on the cathode, an anode current collector (ACC) on the solid-state electrolyte, an insulator layer on the ACC having a sidewall portion, a conductive redistribution layer on the insulator layer, including the sidewall portion, in electrical contact with the ACC, and a printed adhesive on a major surface of the cell. The packaged solid-state battery includes a plurality of the stackable solid-state battery cells and battery terminals in electrical contact with an active layer of each cell. The method includes printing the adhesive on the major surface, which can be the outermost surface of the redistribution layer and the insulator layer, or the substrate surface opposite from the cathode.
Abstract:
A method of making a lithium metal oxide film is disclosed. The method includes blanket-depositing a cathode material, a solid-state electrolyte, and an anode current collector (ACC) material on a substrate, laser-patterning the ACC material to define the solid-state battery cells and form an ACC in each of the cells, and cutting or dicing the solid-state battery cells through the electrolyte and the cathode material to form a cathode in each of the solid-state battery cells. The method avoids issues related to topography and wet patterning when making the cathode, electrolyte and ACC layers. The method also avoids the need to fabricate a physical mask, thereby enabling greater patterning flexibility, higher throughput and lower costs than photolithography.

Abstract:
The present invention relates to surveillance and/or identification devices having capacitors connected in parallel or in series, and methods of making and using such devices. Devices with capacitors connected in parallel, where one capacitor is fabricated with a relatively thick capacitor dielectric and another is fabricated with a relatively thin capacitor dielectric achieve both a high-precision capacitance and a low breakdown voltage for relatively easy surveillance tag deactivation. Devices with capacitors connected in series result in increased lateral dimensions of a small capacitor. This makes the capacitor easier to fabricate using techniques that may have relatively limited resolution capabilities.
Abstract:
Methods of forming contacts (and optionally, local interconnects) using an ink comprising a silicide-forming metal, electrical devices such as diodes and/or transistors including such contacts and (optional) local interconnects, and methods for forming such devices are disclosed. Electrical devices, such as diodes and transistors may be made using such printed contact and/or local interconnects. A metal ink may be printed for contacts as well as for local interconnects at the same time, or in the alternative, the printed metal can act as a seed for electroless deposition of other metals if different metals are desired for the contact and the interconnect lines. This approach advantageously reduces the number of processing steps and does not necessarily require any etching.
