Title: Jfet with built in back gate in either soi or bulk silicon
Inventor: VORA MADHUKAR
IPC: H01L29/10
Filed: 2007-08-09
Abstract: A Junction Field-Effect transistor with no surface contact for the back gate and twice as much transconductance in the channel and with a higher switching speed is achieved by intentionally shorting the channel-well PN junction with the gate region. This is achieved by intentionally etching away field oxide outside the active area at least in the gate region so as to expose the sidewalls of the active area down to the channel-well PN junction or a buried gate which is in electrical contact with the well. Polysilicon is then deposited in the trench and doped heavily and an anneal step is used to drive impurities into the top and sidewalls of the channel region thereby creating a "wrap- around" gate region which reaches down the sidewalls of the channel region to the channel-well PN junction. This causes the bias applied to the gate terminal to also be applied to the well thereby modulating the channel transconductance with the depletion regions around both the gate-channel PN junction and the channel-well PN junction.

Title: An apparatus for secure computation of string comparators
Inventor: DIAMOND JEFF
IPC: G06F7/02
Filed: 2009-05-11
Abstract: We present an apparatus which can be used so that one party learns the value of a string distance metric applied to a pair of strings, each of which is held by a different party, in such a way that none of the parties can learn anything else significant about the strings.  This apparatus can be ap-plied to the problem of linking records from different databases, where privacy and confidentiality concerns prohibit the sharing of records. The apparatus can compute two different string similarity metrics, including the bigram based Dice coefficient and the Jaro-Winkler string comparator. The apparatus can implement a three party protocol for the secure computation of the bigram based Dice coefficient and a two party protocols for the Jaro-Winkler string comparator which are se-cure against collusion and cheating. The apparatus implements a three party Jaro-Winkler string comparator computation which is secure in the case of semi-honest participants
