Exhibit 99.1

Amkor Technology, Inc. Announces Preliminary Third Quarter Results

WEST CHESTER, Penn.--Oct. 15, 1998--Amkor Technology, Inc. (Nasdaq:AMKR) today
announced that it expects revenues for the third quarter ended Sept. 30, 1998 to
be between $385 million and $390 million, with fully diluted earnings per share
between $0.16 and $0.18.

The Company said that revenues were below expectations since unit shipments did
not increase and average selling prices decreased across all product lines more
severely than anticipated. Partially offsetting the negative impact on gross
profits as a result of lower selling prices was a reduction in material costs,
experienced in the quarter.

The Company will release final third quarter results on Oct. 26, 1998 at 1:30
p.m. Pacific time. The conference call number is 719/457-2649. A replay will be
available for one week by calling 719/457-0820.
