An integrated circuit connection is describe that includes a first,
securing member and a second, connection member. The first member, in an
embodiment, is a spike that has a portion of its body fixed in a layer of
an integrated circuit structure and extends outwardly from the integrated
circuit structure. The second material is adapted to form a mechanical
connection to a further electrical device. The second material (e.g.,
solder), is held by the first member to the integrated circuit structure.
The first member increases the strength of the connection and assists in
controlling the collapse of second member to form the mechanical
connection to another circuit. The connection is formed by coating the
integrated circuit structure with a patterned resist and etching the
layer beneath the resist. A first member material (e.g., metal) is
deposited. The resist is removed. The collapsible material is fixed to
the first member.
