A semiconductor device in the first embodiment includes: an electrode pad and a resin projection, formed on an active surface; a conductive film deposited from a surface of the electrode pad to a surface of the resin projection; a resin bump formed with the resin projection and with the conductive film. The semiconductor device is conductively connected to the opposing substrate through the resin bump electrode. The testing electrode is formed with the conductive film that is extended and applied to the opposite side of the electrode pad across the resin projection.

An anisotropic conductive film, and its production method, especially suitable for mounting a semiconductor package and sufficiently satisfying the requirements of higher density mounting because short circuit does not occur in the plane direction of the film even if the pitch of electrodes is small, or suitable for mounting a contact probe because conductive connection not fused with a high current can be ensured with a lower pressure and even a high frequency signal can be dealt with. The anisotropic conductive film contains metal powder having such a shape that many fine metal particles are linked as a conductive component, wherein the length of the chain of metal powder is set not longer than the distance between adjacent electrodes being bonded conductively when a semiconductor package is mounted, and the diameter of the chain is set in the range of 1 μm-20 μm when a contact probe is mounted. At least a part of the film is formed while orienting a chain formed of a paramagnetic metal with a magnetic field.

This utility model relates to a decorative light, and particularly, to a decorative light capable of avoiding an open circuit condition on an entire string of bulbs that operate in series when an individual bulb is removed. The decorative light comprises a socket, a bulb base, a bulb and two terminals, wherein the socket is provided with a retainer therein, which has an opening laterally extending therethrough, and an elastic, conductive ring or coil with a thickness smaller than a width of the opening is disposed within the opening. When the elastic ring or coil is in a natural state, the elastic ring extends outside the retainer through the opening at two sides of the retainer. The bulb base is further provided with an inserting partition at the bottom thereof The elastic conductive ring has two states: one is a separating state where the bulb base is inserted into the socket. In this first state, the inserting partition of the bulb base separates one side of the elastic ring or coil from the corresponding terminals. The other state is a conducting state of the two terminals when the bulb base is removed from the socket. In this second state both sides of the elastic, conductive ring or coil provide contact with the two terminals respectively. This utility model provides a decorative light capable of preventing failure of the complete string of bulbs when any bulb is removed.
