Kulicke & Soffa (K&S) announced an agreement to buy Alphasem on October 12, 2006, then completed the acquisition on November 6. The announced price was $30 million, subject to a working-capital adjustment; K&S later reported paying $27.1 million in cash at closing, also subject to further post-closing adjustments. The deal extended K&S’s semiconductor assembly equipment business from wire bonding into the adjacent field of die bonding.
What K&S announced—and what it paid at closing
K&S said it had signed an agreement to acquire Alphasem from Dover Technologies International, a subsidiary of Dover Corporation, on October 12, 2006. The announced purchase price was $30 million, subject to a working-capital adjustment, and K&S expected the transaction to close around November 3. The announcement described die bonding as an expansion into equipment adjacent to K&S’s established wire-bonding business. K&S announcement
The acquisition closed on November 6, 2006. In its closing release, K&S reported a cash purchase price of $27.1 million after a working-capital adjustment, subject to further post-closing adjustments. The two figures describe different stages of the transaction: the announced headline price and the adjusted cash consideration reported at closing. K&S closing release
Why the acquisition fit K&S’s business
In semiconductor chip assembly, die bonding comes before wire bonding. K&S said the processes typically use adjacent floor space and a common engineering team, making the equipment complementary for customers. It also cited shared functions, software features, subassemblies, and components between die bonders and wire bonders. K&S announcement

K&S equipment segment vice president Christian Rheault called the deal “a natural extension” of its core equipment business into die bonding. Chairman and CEO Scott Kulicke said buying Alphasem was “the most attractive way” for K&S to enter that market. Those statements express management’s rationale at the time, not proof of later integration results. Rheault statement Kulicke statement
What Alphasem made and brought to the deal
Alphasem supplied die-bonder equipment and MEMS packaging equipment. K&S’s announcement highlighted Alphasem’s experience with air bearings and volumetric dispense systems. At closing, K&S reported that Alphasem had approximately $60 million in 2005 sales from die bonders, related materials, and services, and employed 260 people. K&S announcement K&S closing release

The releases document the acquisition’s announcement, closing, consideration, stated strategy, and selected operating figures at the time. They do not establish Alphasem’s present ownership, current product support, or whether management’s anticipated future platforms and integration plans were achieved. This was a specialized industrial-equipment acquisition, not a consumer product purchase.
