Patent CA-2204259-A1 (CA)
Title: A method and a device for telecommunication
Inventor: ANDER CARL
IPC: H04M11/00
Filed: 1995-10-31
Abstract: A method for forwarding and billing a telephone call, wherein a first subscriber telephone is connected to a second subscriber telephone via a standard telephone network. The invention is characterized in that the first subscriber dials a prefix followed by a subscriber number which leads to a third subscriber and a subscriber number which leads to a second subscriber; in that the prefix causes the telephone network to connect the call via the telephone network to a computer unit associated with the third subscriber and connected to the telephone network, and also causes the computer unit to forward the call to the second subscriber via the computer unit, such as to connect the first subscriber with the second subscriber; and in that detection of the prefix in the telephone network causes the network to bill the call between the first and the second subscriber to the subscription of the third subscriber. According to one highly preferred embodiment, the computer unit is caused to transmit information on the call connection between the first subscriber and the second subscriber at given time intervals. The invention also relates to a device.

Title: Contoured-tub fermi-threshold field effect transistor and method of forming same
Inventor: DENNEN MICHAEL WILLIAM
IPC: H01L21/336
Filed: 1995-12-05
Abstract: A Fermi-threshold field effect transistor includes a contoured-tub region of the same conductivity type as the source, drain and channel regions and having nonuniform tub depth. The contoured-tub is preferably deeper under the source and/or drain regions than under the channel region.  Thus, the tub-substrate junction is deeper under the source and/or drain regions than under the channel region. The diffusion capacitance is thereby reduced compared to a tub having a uniform tub depth, so that a high saturation current is produced at low voltages.  The contoured-tub may be formed by an additional implant into the substrate using the gate as a mask.
