Exhibit 99.1

   AMI Semiconductor, Inc. to Acquire Select Businesses of NanoAmp Solutions;
         Acquisition Enhances Ultra Low Power Medical Product Offering

     POCATELLO, Idaho--(BUSINESS WIRE)--July 31, 2006--AMI Semiconductor, Inc.,
subsidiary of AMIS Holdings, Inc. (Nasdaq:AMIS), today announced that it entered
into an agreement to acquire the Ultra Low Power (ULP) six-transistor (6T) SRAM
and medical System-on-Chip (SOC) ASIC businesses of NanoAmp Solutions Inc. for
approximately $21 million in cash, plus an adjustment for closing inventory of
the business. NanoAmp Solutions specializes in low-voltage and ULP memory and
ASIC solutions for the wireless communication, industrial, medical, and
networking market segments. Its ULP SRAM technology implemented in the 180 nm
process is valued by medical customers as embedded IP for implantable medical
SOC applications. Under conditions of the proposed sale, to be structured as an
asset purchase, AMI Semiconductor, Inc. will acquire certain assets and assume
certain liabilities related to NanoAmp Solutions' medical SOC business and its
ULP 6T SRAM business, which collectively employ approximately 25 people in the
United States, Korea and Taiwan.
     "By combining NanoAmp's class-leading ULP SRAM technology with our ULP
mixed-signal and digital signal processing capabilities, we are able to enhance
our core competencies and strengthen our leadership position in the implantable
medical market," stated Christine King, president and CEO of AMI Semiconductor.
"In addition, this acquisition adds medical-qualified ULP SRAM technology to our
core competencies, available as embedded IP or as ASSPs, as well as new design
wins in the 180nm Medical SOC market. This strengthens our commitment to provide
unique, value-add solutions to our medical customers."
     "AMI and NanoAmp are both recognized IC suppliers to the implantable
medical market; the pooling of respective technologies and resources would
strengthen the new team's ability to provide ultra low power, integrated SOC
solutions to serve our customers' future IC requirement," stated Hugo Chan,
president of NanoAmp's Medical Group.
     The businesses to be acquired consist primarily of designs that are still
in development; however, the SRAM business is currently providing revenue,
anticipated at approximately $7 - $8 million for all of 2006. For the balance of
2006, the acquisition is expected to be neutral to non-GAAP earnings per share
and be accretive by $0.01 per share in 2007. The transaction is expected to
close during the third calendar quarter.
