Item 2.01  Completion of Acquisition or Disposition of Assets

On June 23, 2005 Semtech Corporation, through its wholly-owned Swiss subsidiary,
Semtech International AG, acquired all of the outstanding shares of Xemics SA
from twenty-one sellers in a cash for stock transaction pursuant to the Share
Purchase and Sales Agreement ("Agreement") that was previously filed as Exhibit
10.1 to Semtech's Form 8-K filed on June 20, 2005 and that is incorporated
herein by reference. The names of the twenty-one selling shareholders are set
forth in the Agreement.

The transaction with Xemics shareholders is valued at approximately $59 million,
assuming all variable portions of the purchase price are paid and including
payments associated with certain shareholder loans that have been assigned to
and assumed by Semtech International. Semtech International paid $43 million
upon closing of the transaction. An additional $16 million may be payable if
Xemics meets certain performance objectives during an earnout period of
approximately one year. The purchase price is subject to a reduction for social
security, pension and stamp duty obligations to be paid post-closing that are
related to certain employee stock options exercised before closing; this
adjustment will not impact the total cash outlay associated with the
transaction. 

The foregoing description of the terms of the transaction does not purport to be
complete and is qualified in its entirety by the Agreement.
