Abstract: The present invention provides a transparent latch circuit capable of performing a scan test in general scan design (GSD). In the transparent latch circuit a test signal is at a Low level during normal operation. Since a latch stop circuit outputs a High-level latch stop signal, a slave latch circuit has a received signal pass through it directly and a master latch circuit operates as a latch circuit in response to a signal output from an inverter. On the other hand, a test signal is at a High level during scan test. At this point, the latch stop circuit outputs a signal complementary to the signal output from the inverter. Therefore, the master latch circuit and the slave latch circuit operate as latch circuits responding to signals complementary to each other. Thereby, the entire transparent latch circuit operates as a flip-flop circuit.

Abstract: A programmable element that has a first diode having an electrode and a first insulator disposed between the substrate and said electrode of said first device, said first insulator having a first value of a given characteristic, and an FET having an electrode and a second insulator disposed between the substrate and said electrode of said second device, said second insulator having a second value of said given characteristic that is different from said first value. The electrodes of the diode and the FET are coupled to one another, and a source of programming energy is coupled to the diode to cause it to permanently decrease in resistivity when programmed. The programmed state of the diode is indicated by a current in the FET, which is read by a sense latch. Thus a small resistance change in the diode translates to a large signal gain/change in the latch. This allows the diode to be programmed at lower voltages.

Abstract: The preferred embodiment of the present invention overcomes the limitations of the prior art and provides a device and method to increase the latch-up immunity of CMOS devices by forming a non-dopant region near the edge of a dopant region. The preferred embodiment method to increase the latch-up immunity of CMOS devices uses hybrid photoresist to selectively form non-dopant implants near the edges of the N-well and/or P-well. The non-dopant implants suppress diffusion of dopant in the wells resulting in greater control of well spacing, and hence reducing the gain of the parasitic transistor. This reduces the propensity of the CMOS device to latch-up. The preferred embodiment method allows the non-dopant implants to be formed without requiring additional masking steps over the prior art methods.

Abstract: A blocking layer is formed on a hard mask having an initial thickness. Lines are fabricated by patterning the blocking layer and the hard mask to provide a line segment, the line segment having a first dimension measured across the line segment; reacting a surface layer of the line segment to form a layer of a reaction product on a remaining portion of the line segment; and removing the reaction product without attacking the remaining portion of the line segment and without attacking the blocking layer and the substrate to form the line segment with a second dimension across the line segment that is smaller than the first dimension. The blocking layer prevents the formation of reaction product on the hard mask so that the initial thickness of the hard mask is maintained. The blocking layer can also serve as an ARC layer for photoresist patterning so that the use of an additional film layer is not required.
