Abstract: A method of forming a semiconductor device includes providing a substrate including a circuit region and a well strap region, forming a mandrel extending from the circuit region to the well strap region, depositing mandrel spacers on sidewalls of the mandrel, removing the mandrel in the circuit region, while the mandrel in the well strap region remains intact, patterning the substrate with the mandrel spacers in the circuit region and the mandrel in the well strap region as an etch mask, thereby forming at least a first fin in the circuit region and a second fin in the well strap region, and epitaxially growing a first epitaxial feature over the first fin in the circuit region and a second epitaxial feature over the second fin in the well strap region. A width of the second fin is larger than a width of the first fin.

Abstract: A planar array antenna structure includes a substrate, an array antenna, and a bottom ground portion. The substrate has a front surface and a rear surface. The array antenna is composed of a plurality of antenna units and disposed on the front surface of the substrate in a symmetrical and polygonal arrangement. A spaced slot is formed between every two antenna units. The bottom ground portion is polygonal and arranged on the rear surface of the substrate. The bottom ground portion has a plurality of included angles thereon, and one notch is formed between two included angles and the notches are correspondingly arranged to the spaced slots. Accordingly, the planar array antenna structure is used to generate high-gain radiation variations, effectively restrain the isolation between the radiators, and significantly increase overall performance of the antenna.

Abstract: A dual-band antenna used in a portable wireless communication device includes a main antenna body, a feed end, and a grounding end. The feed end and the grounding end are positioned on the main antenna body. The main antenna body includes a matching portion for adjusting the match impendence of the dual-band antenna, a first antenna portion a for transmitting/receiving wireless signals in high frequency bands, and a second antenna portion for transmitting/receiving wireless signals in low frequency bands. The first antenna and the second antenna are connected to two opposition end of the matching portion. The matching portion, the first antenna, and the second antenna are coplanar.

Abstract: An antenna module includes an antenna set, a feeding point and a ground plane. The antenna set includes a first antenna, and a second antenna. The first antenna has a first resonant frequency and the second antenna a second resonant frequency.
