    摘要: Planarization methods for maintaining planar surfaces in the fabrication of such devices as BAW devices and capacitors on a planar or planarized substrate are described. In accordance with the method, a metal layer is deposited and patterned, and an oxide layer is deposited using a high density plasma chemical vapor deposition (HDP CVD) process to a thickness equal to the thickness of the metal layer. The HDP CVD process provides an oxide layer on the patterned metal tapering upward from the edge of the patterned metal layer. Then, after masking and etching the oxide layer from the patterned metal layer, the patterned metal layer and surrounding oxide layer form a substantially planar layer, interrupted by small remaining oxide protrusions at the edges of the patterned layer. These small remaining oxide protrusions may be too small to significantly disturb the flatness of a further oxide or other layer or they may be further mitigated by the application of another HDP CVD oxide film.

    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.
