Abstract: Embodiments of the invention may provide for a CMOS antenna switch, which may be referred to as a CMOS SP4T switch. The CMOS antenna switch may operate at a plurality of frequencies, perhaps around 900 MHz and 1.9 GHz according to an embodiment of the invention. The CMOS antenna switch may include both a receiver switch and a transmit switch. The receiver switch may utilize a multi-stack transistor with body substrate tuning to block high power signals from the transmit path as well as to maintain low insertion loss at the receiver path. On the other hand, in the transmit switch, a body substrate tuning technique may be applied to maintain high power delivery to the antenna. Example embodiments of the CMOS antenna switch may provide for 31 dBm P 1 dB at both bands (e.g., 900 MHz and 1.8 GHz). In addition, a 0.9 dB and −1.1 dB insertion loss at 900 MHz and 1.9 GHz, respectively, may be obtained according to example embodiments of the invention.

Abstract: In the present invention, a semiconductor device includes a first insulation layer formed on a semiconductor substrate, an elevating pad formed on the first insulation layer, a second insulation layer covering the elevating pad, a plurality of fuses formed on the second insulation layer and over the elevating pad, a third insulation layer formed on the fuses, and an opening formed in a top portion of the third insulation layer and over the fuses. With this invention, the horizontal level of the fuses are elevated due to the existence of the elevating pad, which makes the distance between the fuse window and fuses be closer than that of the conventional and that reduces the step difference. Thus, a laser beam can reliably blow out all of the fuses reliably.
