  • Patent number: 8338914
    Abstract: The formation of devices in semiconductor material is provided using an HF/HCL cleaning process. In one embodiment, the method includes forming at least one hard mask overlaying at least one layer of resistive material, forming at least one opening to a working surface of a silicon substrate of the semiconductor device, and cleaning the semiconductor device with a diluted HF/HCL process. The HF/HCL process includes applying a dilute of HF for a select amount of time and applying a dilute of HCL for a specific amount of time. After cleaning with the diluted HF/HCL process, a silicide contact junction is formed in the at least one opening to the working surface of the silicon substrate, and interconnect metal layers are formed.

  • Patent number: 6667523
    Abstract: A semiconductor device or integrated circuit has high and low resistive contacts. Mobility spoiling ions such as carbon are implanted into all contacts of the substrate. High resistive contacts are temporarily covered with an oxide during processing to prevent silicide from forming due to interaction between a siliciding metal and the implanted mobility spoiling ions in the contacts. The resulting high resistance contacts have highly linear I-V curves, even at high voltages. Selective silicide formation converts some of the contacts back to low resistance contacts as a result of interaction between a siliciding metal and the implanted mobility spoiling ions in the low resistance contacts.
