20130032885 | AREA EFFICIENT GRIDDED POLYSILICON LAYOUTS - Gridded polysilicon semiconductor layouts implement double poly patterning to cut polylines of the layout into polyline segments. Devices are arranged on the polyline segments of a common polyline to reduce the area used to implement a circuit structure relative to conventional gridded polysilicon layout. Stacking of PMOS and NMOS devices is enabled by using double poly patterning to implement additional cuts which form additional polyline segments. Metal layer routing may connect nodes of separate polyline segments. | 02-07-2013 |
20150109025 | AREA SAVING IN LATCH ARRAYS - A CMOS device includes a PMOS transistor and an NMOS transistor. The CMOS device further includes a poly interconnect connecting together a drain of the PMOS transistor and a drain of the NMOS transistor. The poly interconnect may be located on an edge of a standard cell including the device. The CMOS device may further include a first interconnect on an MD layer connecting the drain of the PMOS transistor to the poly interconnect, and a second interconnect on the MD layer connecting the drain of the NMOS transistor to the poly interconnect. The PMOS transistor and the NMOS transistor may operate as a CMOS inverter. The CMOS device may be a tristate inverter, and specifically, a tristate inverter within a latch array. | 04-23-2015 |
20150287709 | DOUBLE PATTERNED STACKING TECHNIQUE - A double patterned CMOS device includes a first set of stacked transistors, a second set of stacked transistors, and a set of transistors. The first set of stacked transistors includes first and second transistors. The first transistor has a first transistor active region and the second transistor has a second transistor active region.

The third transistor has a third transistor active region and the fourth transistor has a fourth transistor active region. The set of transistors is adjacent the first set of stacked transistors. The set of transistors includes a fifth transistor. The fifth transistor has a fifth transistor active region. The first, second, third, and fourth transistor active regions satisfy certain distance relationships from each other. | 10-08-2015 |
