    摘要: A method of forming a flash memory cell is disclosed where nitrogen treatment or implantation is employed. Nitrogen introduced into the upper layers of the polysilicon of the floating gate is instrumental in forming an unusually thin layer comprising nitrogen-oxygen-silicon. This N--O--Si layer is formed while growing the bottom oxide layer of the oxide-nitride-oxide, or ONO, the intergate layer between the floating gate and the control gate of the flash memory cell. Nitrogen in the first polysilicon layer provides control for the thickness of the bottom oxide while at the same time suppressing the gradual gate oxidation (GGO) effect in the floating gate. The now augmented ONO composite through the N--O--Si layer provides an enhanced intergate dielectric and hence, a flash memory cell with more precise coupling ratio and better performance.

    摘要: A single-chip common-drain JFET device comprises a drain, two gates and two source arranged such that two common-drain JFETs are formed therewith. Due to the two JFETs merged within a single chip, no wire bonding connection is needed therebetween, thereby without parasitic inductance and resistance caused by bonding wire, and therefore improving the performance and reducing the package cost. The single-chip common-drain JFET device may be applied in buck converter, boost converter, inverting converter, switch, and two-step DC-to-DC converter to improve their performance and efficiency. Alternative single-chip common-drain JFET devices are also provided for current sense or proportional current generation.

    摘要: A fully logic process compatible non-volatile memory cell has a well on a substrate, a pair of source and drain outside the well, a channel between the source and drain, a control gate in the well, and a floating gate having a first portion above the channel, and a second portion above the well. The control gate includes two regions having opposite conductivity types and a third region between the two regions and under the second portion of the floating gate, and thus eliminates the parasitic depletion capacitor in the coupling path of the cell, thereby improving the coupling ratio.

    摘要: A level shift circuit includes an input stage and an output stage coupled to each other by two nodes. The input stage changes the voltages on the nodes according to an input signal, and the output stage determines an output signal according to the voltages on the two nodes. In a transition state, the input stage provides a large current to charge or discharge the first node or the second node so as to quickly change the voltage thereon. In a steady state, the input stage lowers the current so as to reduce power consumption.

    摘要: A plurality of switches, an inductor and two capacitors are configured to be a boost-inverting converter. To operate the converter in a boost-inverting mode, a control apparatus and method switch the switches such that the inductor is energized in a first phase, the first capacitor is discharged to produce an inverting voltage in a second phase, and the capacitor Cout1 is discharged to produce the inverting voltage and the second capacitor is charged to produce a boost voltage in a third phase. Therefore, the boost-inverting converter has lower peak inductor current and less power loss, and the limitation to the switch design for the boost-inverting converter is relaxed.
