  • Patent number: 7141348
    Abstract: This invention discloses a releasable adhesion layer having good adhesion during high temperature fabrication process in the absence of light, and delaminating at a lower temperature in the presence of light. One embodiment of this invention is a film of polymer whose thermal decomposition temperature changes drastically upon photoexposure. These materials, prior to photoexposure, can withstand temperatures in the range of approximately 200° C. to 300° C. without decomposition, yet decompose at around 100° C. with photoexposure. The releasable adhesion layer can be used in a thermal transfer element, sandwiching a donor substrate and a transfer layer having a plurality of multicomponent transfer units. In the absence of light, the releasable adhesion layer can sustain high temperature processing of these multicomponent transfer units. By photoexposing according to a pattern, the photoexposed multicomponent transfer units can be selectively released at a low temperature to transfer to a receptor.

  • Patent number: 6705816
    Abstract: A wafer transfer apparatus provides a rotational and translational motions using only one stationary motor drive. The apparatus includes a drive assembly and a transport arm assembly. The transport arm assembly includes a transport arm rotatably attached to a linking arm. The linking arm is fixedly attached to a sleeve, which is rotatably attached to a housing. A shaft runs axially through the sleeve, and coupled with the transport arm so that rotation of the sleeve relative to the shaft causes the movement of the transport arm assembly. A locking mechanism allows the shaft to be locked to the housing or to the sleeve. A motor fixedly attached to the housing and operational attached to the sleeve. When the shaft is locked to the sleeve, the motor rotates the sleeve and the shaft simultaneously, which effects rotation of the transfer arm relative to the housing.

  • Patent number: 6689220
    Abstract: A process system and a deposition method for depositing a highly controlled layered film on a workpiece is disclosed. The basic component of the present invention apparatus is a pulsing plasma source capable of either exciting or not-exciting a first precursor. The pulsing plasma source includes an energy source to generate a plasma, and a plasma adjusting system to cause the plasma to either excite or not-excite a precursor. The precursor could flow continuously (an aspect totally new to ALD), or intermittently (or pulsing, standard ALD operation process). The present invention further provides a method to deposit highly controlled layered film on a workpiece. The method comprises the steps of pulsing the plasma to excite/not-excite the precursors and the ambient to deposit and modify the depositing layers. This procedure then can be repeated alternately until the film reaches a desired thickness.

  • Patent number: 6670266
    Abstract: A method has been provided for improving the adhesion of copper to a nitrided metal diffusion barrier material, such as TiN, in an integrated circuit substrate. The method provided a multilayered diffusion barrier structure, comprising a conducting diffusion barrier layer and a poorly conducting adhesion-promoter layer in selected locations. The formation of a poorly conducting adhesion-promoter layer in selected locations permits the optimization of both contact resistance and adhesion property. The poorly conducting adhesion-promoter layer is formed either by the partial incorporation of oxygen into the diffusion barrier or by deposition in an oxygen ambient.
