Abstract: Light emitting devices employing one or more Group III-Nitride polarization junctions. A III-N polarization junction may include two III-N material layers having opposite crystal polarities. The opposing polarities may induce a two-dimensional charge carrier sheet within each of the two III-N material layers. Opposing crystal polarities may be induced through introduction of an intervening material layer between two III-N material layers. Where a light emitting structure includes a quantum well (QW) structure between two Group III-Nitride polarization junctions, a 2D electron gas (2DEG) induced at a first polarization junction and/or a 2D hole gas (2DHG) induced at a second polarization junction on either side of the QW structure may supply carriers to the QW structure. An improvement in quantum efficiency may be achieved where the intervening material layer further functions as a barrier to carrier recombination outside of the QW structure.

Abstract: Technologies for thermoelectric enhanced cooling on an integrated circuit die are disclosed. In the illustrative embodiment, one or more components are created on a top side of an integrated circuit die, such as a power amplifier, logic circuitry, etc. The one or more components, in use, generate heat that needs to be carried away from the components. A thermoelectric cooler can be created on a back side of the die in order to facilitate removal of heat from the component. In some embodiments, additional structures such as vias filled with high-thermal-conductivity material may be used to further improve the removal of heat from the component.

Abstract: Techniques are disclosed for forming high frequency film bulk acoustic resonator (FBAR) devices having multiple resonator thicknesses on a common substrate. A piezoelectric stack is formed in an STI trench and overgrown onto the STI material. In some cases, the piezoelectric stack can include epitaxially grown AlN. In some cases, the piezoelectric stack can include single crystal (epitaxial) AlN in combination with polycrystalline (e.g., sputtered) AlN. The piezoelectric stack thus forms a central portion having a first resonator thickness and end wings extending from the central portion having a different resonator thickness. Each wing may also have different thicknesses. Thus, multiple resonator thicknesses can be achieved on a common substrate, and hence, multiple resonant frequencies on that same substrate. The end wings can have metal electrodes formed thereon, and the central portion can have a plurality of IDT electrodes patterned thereon.

Abstract: Integrated circuits with III-N metal-insulator-semiconductor field effect transistor (MISFET) structures that employ one or more gate dielectric materials that differ across the MISFETs. Gate dielectric materials may be selected to modulate dielectric breakdown strength and/or threshold voltage between transistors. Threshold voltage may be modulated between two MISFET structures that may be substantially the same but for the gate dielectric. Control of the gate dielectric material may render some MISFETs to be operable in depletion mode while other MISFETs are operable in enhancement mode. Gate dielectric materials may be varied by incorporating multiple dielectric materials in some MISFETs of an IC while other MISFETs of the IC may include only a single dielectric material. Combinations of gate dielectric material layers may be selected to provide a menu of low voltage, high voltage, enhancement and depletion mode MISFETs within an IC.

Abstract: Disclosed herein are IC structures, packages, and devices assemblies that use ions or fixed charge to create field plate structures which are embedded in a dielectric material between gate and drain electrodes of a transistor. Ion- or fixed charge-based field plate structures may provide viable approaches to changing the distribution of electric field at a transistor drain to increase the breakdown voltage of a transistor without incurring the large parasitic capacitances associated with the use of metal field plates. In one aspect, an IC structure includes a transistor, a dielectric material between gate and drain electrodes of the transistor, and an ion- or fixed charge-based region within the dielectric material, between the gate and the drain electrodes. Such an ion- or fixed charge-based region realizes an ion- or fixed charge-based field plate structure. Optionally, the IC structure may include multiple ion- or fixed charge-based field plate structures.

Abstract: Techniques are disclosed herein for ferroelectric-based field-effect transistors (FETs) with threshold voltage (VT) switching for enhanced RF switch transistor on-state and off-state performance. Employing a ferroelectric gate dielectric layer that can switch between two ferroelectric states enables a higher VT during the transistor off-state (VT,hi) and a lower VT during the transistor on-state (VT,lo). Accordingly, the transistor on-state resistance (Ron) can be maintained low due to the available relatively high gate overdrive (Vg,on−VT,lo) while still handling a relatively high maximum RF power in the transistor off-state due to the high VT,hi −Vg,off value. Thus, the Ron of an RF switch transistor can be improved without sacrificing maximum RF power, and/or vice versa, the maximum RF power can be improved without sacrificing the Ron. A ferroelectric layer (e.g., including HfxZryO) can be formed between a transistor gate dielectric layer and gate electrode to achieve such benefits.
