    摘要: Titanium-tungsten alloy based mirrors and electrodes in bulk acoustic wave devices simplify processing by eliminating the need for adhesion, barrier and seed layers, and preserve the advantages of tungsten layers. Alternate layers of high and low acoustic impedance materials are use, wherein the high acoustic impedance layers are titanium-tungsten alloy layers, preferably deposited by physical vapor deposition, and isotropically patterned with a wet etch. SiO2 is preferably used for the low acoustic impedance layers, though other low acoustic impedance materials may be used if desired. Electrodes and loads may also be a Titanium-tungsten alloy. Titanium-tungsten alloys in the range of 3 to 15 percent of titanium by weight are preferred.

    摘要: Semiconductor devices, such as laterally diffused metal oxide semiconductor (LDMOS) devices, are described that have a field plate connected to a gate of the device. In one or more implementations, the semiconductor devices include a substrate having a source region of a first conductivity type and a drain region of the first conductivity type. A gate is positioned over the surface and between the source region and the drain region. The gate is configured to receive a voltage so that a conduction region may be formed at least partially below the gate to allow majority carriers to travel between the source region and the drain region. The device also includes a field plate at least partially positioned over and connected to the gate. The field plate is configured to shape an electrical field generated between the source region and the drain region when a voltage is applied to the gate.

    摘要: Embodiments of the present invention provide systems, devices and methods for improving both the bandwidth of a BAW resonator bandpass filter and the suppression of out-of-band frequencies above the passband. In various embodiments of the invention, blocker inductors are located in series between the filter input and the filter output to realize both bandwidth enhancement and improved out-of-band frequency rejection. For example, a first blocker inductor may be located at the input and a second blocker inductor may be located at the output of a BAW resonator bandpass filter.
