  • Patent number: 7071710
    Abstract: The apparatus for detecting the effects of interconnect resistance and capacitance (RC) in a logic circuit includes a first ring oscillator with the interconnect RC parasitics in a logic circuit and a minimum reference ring oscillator without the interconnect RC parasitic in a logic circuit multiplexed to have common stages to obtain delay with and without the parasitics of the interconnect RC. The frequency difference between the first ring oscillator frequency and the minimum reference ring oscillator frequency is determined to detect the effects of the interconnect RC in the logic circuit.
    Type: Grant

  • Publication number: 20020053694
    Abstract: In one embodiment, the present invention provides a method of forming a dynamic random access memory device which utilizes self-aligned contact pads 40a and 40b for the bit line and storage node contacts. A transfer gate 14 is formed at the fact of a semiconductor region 30. The semiconductor 30 includes a bit line contact region 44 and storage node contact region adjacent opposite edges of the transfer gate 14. Transfer gate 14 is surrounded with an insulating material 34/38. A conductive layer 40 is formed over the transfer gate 14, over the bit line contact region 44 and over the storage node contact region. This conductive layer 40 is then etched so that a first portion 40a of the conductive layer 40 provides an electrical contact to the bit line contact region 44 and a second portion 40b of the conductive layer 40 provides an electrical contact to the storage node contact region.

  • Patent number: 5162261
    Abstract: A sputter-etch process is used to etch vias having substantially vertical sidewalls, such that a sloped sidewall is formed. Using a silicon dioxide layer in which to form the vias, slopes of approximately 45.degree. may be obtained. A second insulator layer may be provided to protect the leads and other portions of the device during the sputter-etch to prevent damage.
