  • Patent number: 6133084
    Abstract: A method of fabricating a static random access memory. A gate oxide layer is formed on a substrate having active regions of an access transistor and a drive transistor. A Polysilicon layer is formed on the gate oxide layer. A germanium implantation is performed on the polysilicon layer of the active region of the drive region to form a polysilicon germanium layer. Thereafter, the polysilicon layer and the polysilicon germanium layer are patterned to form a poly gate and a polysilicon germanium gate on the active regions of the access transistor and the drive transistor. A lightly doped region is formed in the substrate beside the gates. A spacer is then formed on the sidewall of the gates. A heavily doped region is formed in the substrate beside the spacer.

  • Patent number: 6104281
    Abstract: An RF tag has an enable/disable circuit connected to a critical part of an electronic object/circuit, e.g. a computer mother board. The critical part of the circuit is any circuit component and/or connection that can enable and/or disable the electric circuit operation. Signals are sent to the tag to change data in the tag memory which causes the enable/disable tag circuit to control the critical part to enable and disable the electric circuit. A system checks the status of the tag, e.g. the electronic circuit was paid for, before enabling the electronic circuit.

  • Patent number: 6103457
    Abstract: Disclosed is a method for reducing faceting of a photoresist layer during an etch process. The method includes depositing a metallization layer on a semiconductor substrate, and forming a photoresist layer over at least a portion of the metallization layer. The method also includes treating the photoresist layer with a first plasma so as to harden the photoresist layer against a metal etching plasma. The method further includes exposing the metallization layer and the photoresist layer to the metal etching plasma. The metal etching plasma etches the metallization layer at a substantially faster rate than the treated photoresist layer so that faceting on the photoresist layer is substantially reduced.
