摘要: An LDMOS is formed with a field plate over the n− drift region, coplanar with the gate stack, and having a higher work function than the gate stack. Embodiments include forming a first conductivity type well, having a source, surrounded by a second conductivity type well, having a drain, in a substrate, forming first and second coplanar gate stacks on the substrate over a portion of the first well and a portion of the second well, respectively, and tuning the work functions of the first and second gate stacks to obtain a higher work function for the second gate stack. Other embodiments include forming the first gate stack of a high-k metal gate and the second gate stack of a field plate on a gate oxide layer, forming the first and second gate stacks with different gate electrode materials on a common gate oxide, and forming the gate stacks separated from each other and with different gate dielectric materials.

摘要: A bonded device having at least one porosified surface is disclosed. The porosification process introduces nanoporous holes into the microstructure of the bonding surfaces of the devices. The material property of a porosified material is softer as compared to a non-porosified material. For the same bonding conditions, the use of the porosified bonding surfaces enhances the bond strength of the bonded interface as compared to the non-porosified material.

摘要: Embodiments of a simple and cost-free multi-time programmable (MTP) structure for non-volatile memory cells are presented. The memory cell includes a substrate, a first transistor having a select gate and a second transistor having a floating gate. The select and floating gates are adjacent to one another and disposed over a transistor well. The transistors include first and second S/D regions disposed adjacent to the sides of the gates. A control gate is disposed over a control well. The control gate is coupled to the floating gate and includes a control capacitor. An erase terminal is decoupled from the control capacitor and transistors.
