Abstract:
A method for fabricating a silicon-oxide-nitride-oxide-silicon (SONOS) non-volatile memory cell, wherein the method comprises steps as following: a pad oxide layer and a first hard mask layer are sequentially formed on a substrate. The pad oxide layer and the first hard mask layer are then etched through to form an opening exposing a portion of the substrate. Subsequently, an oxide-nitride-oxide (ONO) structure with a size substantially less than or equal to the opening is formed to coincide with the portion of the substrate exposed from the opening.
Abstract:
A method for disposing an RFID tag and a system thereof are provided. The RFID tag is disposed on a revolving region of an object. When the object rolls on a transporting platform, the object revolves around the revolving region. Therefore, an RFID reader reads a signal data transmitted from the RFID tag on the revolving region. In addition, the method can also be applied to a model that an object wraps a revolving axis of a transporting platform, and an RFID tag is disposed on a revolving region of the revolving axis of the transporting platform. When the revolving axis of the transporting platform rotates, an RFID reader can read correctly a signal data transmitted by the RFID tag on the revolving region of the revolving axis.

Abstract:
The present invention provides a wireless transmit/receive unit, comprising a feeding connecting line, a first radiating line, a second radiating line, a third radiating line and a fourth radiating line, wherein the third radiating line is longer than the first radiating line and the first radiating line is longer than the second radiating line that provides different current paths for getting a broader bandwidth. The first, second and third radiating lines are connected parallel for enhancing an antenna pattern being perpendicular thereto, and form a series capacity between the first and the third radiating lines. The fourth radiating line vertically connects between the third radiating line and a grounding line for forming a grounding capacity. The printed antenna can be reduced in size by the effect of the two capacities. The wireless transmit/receive unit can provide a better isolation with others by the direction enforced pattern and the reduced size.
Abstract:
A method for fabricating a semiconductor device is described. A stacked gate dielectric is formed over a substrate, including a first dielectric layer, a second dielectric layer and a third dielectric layer from bottom to top. A conductive layer is formed on the stacked gate dielectric and then patterned to form a gate conductor. The exposed portion of the third and the second dielectric layers are removed with a selective wet cleaning step. S/D extension regions are formed in the substrate with the gate conductor as a mask. A first spacer is formed on the sidewall of the gate conductor and a portion of the first dielectric layer exposed by the first spacer is removed. S/D regions are formed in the substrate at both sides of the first spacer. A metal silicide layer is formed on the S/D regions.
