    摘要: Disclosed is a method of fabricating a field effect transistor. In the method, a gate stack on a top surface of a semiconductor substrate is formed, and then a first spacer is formed on a sidewall of the gate stack. Next, a silicide self-aligned to the first spacer is deposited in/or on the semiconductor substrate. Subsequently a second spacer covering the surface of the first spacer, and a contact liner over at least the gate stack, the second spacer and the silicide, are formed. Then an interlayer dielectric over the contact liner is deposited. Next, a metal contact opening is formed to expose the contact liner over the silicide. Finally, the opening is extended through the contact liner to expose the silicide without exposing the substrate.

    摘要: Disclosed is a method of forming an integrated circuit structure having first-type transistors, such as P-type field effect transistors (PFETs) and complementary second-type transistors, such as N-type field effect transistors (NFETs) on the same substrate. More specifically, the invention forms gate conductors above channel regions in the substrate, sidewall spacers adjacent the gate conductors, and source and drain extensions in the substrate. The sidewall spacers are larger (extend further from the gate conductor) in the PFETs than in the NFETs. The sidewall spacers align the source and drain extensions during the implanting process. Therefore, the larger sidewall spacers position (align) the source and drain implants further from the channel region for the PFETs when compared to the NFETs. Then, during the subsequent annealing processes, the faster moving PFET impurities will be restrained from diffusing too far into the channel region under the gate conductor. This prevents the short channel effect that occurs when the source and drain impurities extend too far beneath the gate conductor and short out the channel region.

    摘要: A electrostatic adhesion tester for thin film conductors. In one embodiment, a device is provided for testing the adhesion strength of a thin film conductor that has been formed upon a substrate. The device includes an adhesion tester that is primarily comprised of a conducting portion. The conducting portion is applied to the thin film conductor so that it does not physically contact the thin film conductor, but leaves a small space there between. A power supply may further be provided for coupling to either the adhesion tester, the thin film conductor, or both in order to create a potential difference between the conducting portion and the thin film conductor. The potential difference creates an electric field between the conducting portion and the thin film conductor that induces stress in the thin film conductor. A measuring device may also be provided for coupling to the adhesion tester and the thin film conductor in order to measure an electrical parameter of the electric field, which is indicative of the adhesion strength.

    摘要: Contact with a floating body of an FET in SOI may be formed in a portion of one of the two diffusions of the FET, wherein the portion of the diffusion (such as N−, for an NFET) which is “sacrificed” for making the contact is a portion of the diffusion which is not immediately adjacent (or under) the gate. This works well with linked body FETs, wherein the diffusion does not extend all the way to BOX, hence the linked body (such as P−) extends under the diffusion where the contact is being made. An example showing making contact for ground to two NFETs (PG and PD) of a 6T SRAM cell is shown.

    摘要: The present invention provides an interconnect structure (of the single or dual damascene type) and a method of forming the same, in which a dense (i.e., non-porous) dielectric spacer is present on the sidewalls of a dielectric material. More specifically, the inventive structure includes a dielectric material having a conductive material embedded within at least one opening in the dielectric material, wherein the conductive material is laterally spaced apart from the dielectric material by a diffusion barrier, a dense dielectric spacer and, optionally, an air gap. The presence of the dense dielectric spacer results in a hybrid interconnect structure that has improved reliability and performance as compared with existing prior art interconnect structures which do not include such dense dielectric spacers. Moreover, the inventive hybrid interconnect structure provides for better process control which leads to the potential for high volume manufacturing.
