ITEM 5.02 DEPARTURE OF DIRECTORS OR PRINCIPAL OFFICERS; ELECTION OF
DIRECTORS; APPOINTMENT OF PRINCIPAL OFFICERS

     Effective April 11, 2005, David M. Rickey resigned from the AMIS Holdings,
Inc. Board of Directors, as previously announced.

     On April 12, 2005 AMIS Holdings, Inc. issued a press release announcing
that on April 11, 2005, William N. Starling was appointed to its Board of
Directors to fill the vacancy created by Mr. Rickey's resignation. In addition,
Mr. Starling was appointed to the Audit Committee of the Board of Directors. A
copy of the press release is attached as Exhibit 99.1 to this current report on
Form 8-K and incorporated herein by reference.

     Related Party Transactions: In September 2004, AMI Semiconductor, Inc.
("AMIS"), a wholly-owned subsidiary of AMIS Holdings, Inc. signed a memorandum
of understanding with Synecor, LLC, of which Mr. Starling is chief executive
officer and a managing member. In the memorandum of understanding, AMIS and
Synecor agreed that they intend to enter into a strategic business relationship
whereby AMIS would be the exclusive supplier to Synecor and its affiliates of
digital and mixed signal application specific integrated circuits ("ASICs") for
use in medical products. The parties contemplate entering into definitive
agreements specifying the details of this relationship but have not yet done so.
AMIS is currently in the development phase of two ASIC devices for
Interventional Rhythm Management ("IRM"), an affiliate of Synecor. Mr. Starling
is the chief executive officer of IRM. In 2004, IRM paid AMIS $218,233 in
nonrecoverable engineering charges associated with the development of those ASIC
devices.
