    Abstract: The present invention relates to a semiconductor package. The semiconductor package includes a substrate, at least one chip, a plurality of conductive elements, a plurality of first conductors and a molding compound. The substrate has a plurality of first pads and a solder mask. The first pads are exposed to a first surface of the substrate, and the material of the first pads is copper. The solder mask is disposed on the first surface, contacts the first pads directly, and has at least on opening so as to expose part of the first pads. The chip is mounted on the first surface of the substrate. The conductive elements electrically connect the chip and the substrate. The first conductors are disposed on the first pads. The molding compound is disposed on the first surface of the substrate, and encapsulates the chip, the conductive elements and part of the first conductors. Whereby, the solder mask contacts the first pads directly, and thus results in higher bonding strength, so as to avoid the bridge between the first conductors caused by the first conductors permeating into the interface between the solder mask and the first pads.

The voltage input unit has at least one input terminal and at least one output terminal provides a DC voltage. The comparing unit receives the DC voltage and generates a comparison control signal according to a comparison result obtained by comparing a voltage of a positive voltage terminal with a voltage of a negative voltage terminal. The latch unit is connected to the comparing unit and the voltage input unit. The voltage output unit connected to the latch unit receives the DC voltage from the voltage input unit. The latch unit selectively provides the DC voltage to the voltage output unit according to the comparison control signal.

    Abstract: A method for preparing a gate oxide layer is described. First, a trench surrounding an active area is formed in a substrate, and a dielectric block is then formed in the trench such that an upper surface of the dielectric block is not aligned with that of the substrate. Subsequently, an ion implantation process is performed to implant nitrogen-containing dopants into the substrate in the active area, and a thermal oxidation process is then performed to form a gate oxide layer on the surface of the substrate in the active area. Particularly, the concentration of the nitrogen-containing dopants at the center of the active area is higher than that at the edge of the active area. The nitrogen-containing dopants inhibit the reaction rate of the thermal oxidation process, so as to prevent the gate oxide layer from thinning at the edge near the trench.
