Abstract: A finFET block architecture includes a first set of semiconductor fins having a first conductivity type, and a second set of semiconductor fins having a second conductivity type. An inter-block insulator is placed between outer fins of the first and second sets. A patterned gate conductor layer includes a first plurality of gate traces extending across the set of fins in the first block without crossing the inter-block insulator, and a second plurality of gate traces extending across the set of fins in the second block without crossing the inter-block insulator. Patterned conductor layers over the gate conductor layer are arranged in orthogonal layout patterns, and include an inter-block connector arranged to connect gate traces in the first and second blocks.

Abstract: Two retention flip-flop topologies that utilize a data retention control circuit and a slave/retention latch (sub-circuit) to reliably retain a data bit during standby/sleep operating modes without the need for a local clock signal. The slave/retention latch is controlled using a local clock signal to store sequentially received data bit values during normal operating modes. During standby/sleep modes, the local clock signal is de-activated (i.e., by turning off the supply voltage provided to the local clock generator circuit), and the data retention control circuit operates in accordance with an externally supplied retention enable control signal to both isolate and control the slave/retention latch such that a last-received data bit value is reliably retained in the slave/retention latch. When normal operation is resumed, the local clock signal is re-activated, and the data retention control circuit controls the slave/retention latch to pass the last-received data bit value to an output driver.

Abstract: A finFET block architecture uses end-to-end finFET blocks in which the fin lengths are at least twice the contact pitch, whereby there is enough space for interlayer connectors to be placed on the proximal end and the distal end of a given semiconductor fin, and on the gate element on the given semiconductor fin. A first set of semiconductor fins having a first conductivity type and a second set of semiconductor fins having a second conductivity type can be aligned end-to-end. Interlayer connectors can be aligned over corresponding semiconductor fins which connect to gate elements.

Abstract: An integrated circuit created from a cell library of compact cells. The cell library includes cells having a metal trace routed along the boundary of the cells for carrying a power supply voltage. The cells also include another metal trace routed along the interior of the cells for carrying another power supply voltage. A cell pin carrying an input signal or output signal of the cell is located outside of the region between the two power rails. By routing the power supply voltages and cell pins of the cell in this manner, the integrated circuit created from the cell is extremely compact while still complying with various design rules.
