Patent number: 9444029Abstract: A method of forming a piezoelectronic transistor (PET), the PET, and a semiconductor device including the PET are described. The method includes forming a piezoelectric (PE) element with a trench and forming a pair of electrodes on the PE element in a coplanar arrangement in a first plane, both of the pair of electrodes being on a same side of the PE element. The method also includes forming a piezoresistive (PR) element above the pair of electrodes and forming a clamp above the PR element. Applying a voltage to the pair of electrodes causes displacement of the PE element perpendicular to the first plane.Type: GrantFiled: June 23, 2015Date of Patent: September 13, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Brian A.

Patent number: 5387134Abstract: An electrical connector system includes first and second electrical connectors mateable in a given general direction (A). Each connector includes a housing having a mating end and at least a pair of terminals mounted on the housing. The pair of terminals of each connector have contact portions engageable with the contact portions of the pair of terminals of the other connector. The contact portions of the terminals of at least one of the connectors are at angles to the mating direction to define a generally V-shaped engaging configuration. The contact portions of the terminals of at least one of the connectors are resilient. Therefore, wiping engagement between the respective terminals is effected during mating of the connectors, and the resilient contact portions are effective to store energy upon mating of the connectors, which energy is effective to assist in unmating of the connectors.Type: GrantFiled: July 9, 1993Date of Patent: February 7, 1995Assignee: Molex IncorporatedInventors: Brian Bryce, Patrick G.

Patent number: 5338230Abstract: An electrical connector assembly is disclosed for connecting a mating connector to a printed circuit board. The assembly includes a dielectric housing having a plurality of terminal-receiving cavities and a plurality of terminals insertable into the cavities. Each terminal includes a base section insertable into a respective cavity in an insertion direction for securing the terminal in the cavity. The terminal includes a tail section for contacting the printed circuit board and spring contact beam for electrically engaging a conductor of the mating connector. The tail section and the spring contact beam extend from the base section and are spaced apart transverse to the insertion direction, whereby an insertion tool can be inserted therebetween into engagement with the base section to readily force the terminal into its terminal-receiving cavity.Type: GrantFiled: June 29, 1993Date of Patent: August 16, 1994Assignee: Molex IncorporatedInventors: Brian Bryce, Mathew Wilhite
