摘要： One exemplary disclosed embodiment comprises a semiconductor package including a vertical conduction control transistor and a vertical conduction sync transistor. The vertical conduction control transistor may include a control source, a control gate, and a control drain that are all accessible from a bottom surface, thereby enabling electrical and direct surface mounting to a support surface. The vertical conduction sync transistor may include a sync drain on a top surface, which may be connected to a conductive clip that is coupled to the support surface. The conductive clip may also be thermally coupled to the control transistor. Accordingly, all terminals of the transistors are readily accessible through the support surface, and a power circuit, such as a buck converter power phase, may be implemented through traces of the support surface. Optionally, a driver IC may be integrated into the package, and a heatsink may be attached to the conductive clip.

摘要： Method and device for measurement compensation for inter-system reselection and handover in a dual-mode terminal are disclosed. The method comprises: a GSM physical layer reporting measured RSCP and Ec/No values of a 3G neighbor cell to a radio resource management layer with inter-layer primitives; the radio resource management layer receiving the inter-layer primitives carrying the RSCP and Ec/No values reported by the physical layer, and performing measurement compensation for the inter-layer primitives in the radio resource management layer. Since the measurement compensation is performed in the radio resource management layer of the terminal, the terminal preferably resides on 3G network when detecting the 3G network. It can be applied to measurement compensation for the inter-system reselection and handover when 2G and 3G mobile communication systems co-exist. The terminal is more easily retained on the network of one of the systems and allowed to make a priority selection of the networks.

摘要： Disclosed is a method for fabricating a shallow and narrow trench field-effect transistor (trench FET). The method includes forming a trench within a semiconductor substrate of a first conductivity type, the trench including sidewalls and a bottom portion. The method further includes forming a substantially uniform gate dielectric in the trench, and forming a gate electrode within said trench and over said gate dielectric. The method also includes doping the semiconductor substrate to form a channel region of a second conductivity type after forming the trench. In one embodiment, the doping step is performed after forming the gate dielectric and after forming the gate electrode. In another embodiment, the doping step is performed after forming the gate dielectric, but prior to forming the gate electrode. Structures formed by the invention's method are also disclosed.
