Abstract: Substrate cleaning equipment includes a substrate holder which supports a substrate, a swing body, a head, a first cleaning liquid supply structure, and a second cleaning liquid supply structure. The swing body moves along a sweep line on a main surface of the substrate. The head is coupled to the swing body and includes a pad attachment surface facing the substrate holder. The first cleaning liquid supply structure is coupled to the swing body and sprays a first cleaning liquid onto the main surface of the substrate. The second cleaning liquid supply structure sprays a second cleaning liquid onto the main surface of the substrate. A buffing pad is attached to the pad attachment surface.

Abstract: In one embodiment, a connector is made using a mixture of insulating silicone powder and conductive powder. The connector comprises a connector body formed from the insulating silicone powder and on or more preferably regularly arrayed conductive silicone members that are formed by migrating the conductive powder to a site of the connector corresponding to a solder ball of the semiconductor package. The conductive silicone member comprises a high-density conductive silicone part formed to be proximate an upper surface of the connector body and to protrude therefrom and a low-density conductive silicone part formed in substantial vertical alignment beneath the high-density conductive silicone part, the low-density conductive silicone part having a lower surface exposed from a lower surface of the connector body.
