摘要:
A force input control device suitable for high-volume applications such as cell phones, portable gaming devices and other handheld electronic devices is disclosed. The device comprises a force sensor die formed within semiconductor substrate and containing a force sensor providing electrical output signal in response to applied external force, connection elements for either flip chip mounting or wire bonding. Signal conditioning and processing integrated circuit is integrated within the device. A package enclosing at least a portion of the force sensor die and comprising a force-transferring element coupled to the sensor die for transferring an external force to the force sensor die. A button, which has multiple ergonomical designs, is mechanically coupled to the force-transferring element of the package for providing an interface with the external force.

Systems in accordance with the present invention can include a tip contactable with a media, the media including a substrate and a plurality of cells disposed over the substrate, one or more of the cells being electrically isolated from the other of the cells by a material having insulating properties. One or more of the plurality of cells can include a phase change material. The media is either grounded or electrically connected with a voltage source such that when the tip is placed in contact with the media and a voltage is applied to the tip, a current is drawn through the cell over which the tip is arranged. The current is drawn through the isolated cell at least a portion of the phase change material within the cell beneath the tip is heated to a sufficient temperature such that the material become amorphous in structure. The current is then removed from the phase change material, which is quickly cooled to form an amorphous domain having a resistance representing a “1” (or a “0”). In another embodiment the one or more of the plurality of cells can include a polarity dependent material. In an embodiment, the one or more cells can have a sidewall structure that tapers along the depth of the cell so that the cell has a wider cross-section near where a tip contacts the media and a narrower cross-section near where the cell contacts one of the substrate and an underlayer.

An embodiment of a probe storage device in accordance with the present invention can include an electrostatic actuator for controlling the z-position of a cantilever having a contact probe tip extending therefrom. The electrostatic actuator can comprise two electrodes: the cantilever and a conductive portion in overlapping proximity to the cantilever. By controlling the z-position of the cantilever, the contact probe tip can be selectively engaged and disengaged from a surface of a memory media, thereby allowing the contact probe to selectively read from and/or write to the memory media.
