摘要:
A semiconductor device (200) comprising a semiconductor substrate (210) having source and drain regions (530, 540) located in the semiconductor substrate (210) and having similar doping profiles, wherein a channel region (550) extends from the source region (530) to the drain region (540). The semiconductor device (200) also comprises a dielectric layer (230) located over the source and drain regions (530, 540), the dielectric layer (230) having first and second thicknesses (T1, T2) wherein the second thickness (T2) is substantially less than the first thickness (T1) and is partially located over the channel region (550). The semiconductor device (200) also comprises a gate (510) located over the dielectric layer (230) wherein the second thickness (T2) is located between an end (515) of the gate (510) and one of the source and drain regions (530, 540).
摘要:
A method for manufacturing a semiconductor device that comprises forming an oxide layer over a substrate. A polysilicon layer is disposed outwardly from the oxide layer, wherein the polysilicon layer forms a floating gate. A PSG layer is disposed outwardly from the polysilicon layer and planarized. The device is pattern etched to form a capacitor channel, wherein the capacitor channel is disposed substantially above the floating gate formed from the polysilicon layer. A dielectric layer is formed in the capacitor channel disposed outwardly from the polysilicon layer. A tungsten plug operable to substantially fill the capacitor channel is formed.
摘要:
A transistor is formed in a semiconductor substrate. A deep n-well region is used in conjunction with a shallow n-well region. A lightly doped drain extension region is disposed between a drain region and a gate conductor. The use of the regions and against the backdrop of region provides for a very high breakdown voltage as compared to a relatively low channel resistance for the device.
