Abstract: An integrated circuit structure includes a sub-fin having (i) a first portion including a p-type dopant and (ii) a second portion including an n-type dopant. A first body of semiconductor material is above the first portion of the sub-fin, and a second body of semiconductor material is above the second portion of the sub-fin. In an example, the first portion of the sub-fin and the second portion of the sub-fin are in contact with each other, to form a PN junction of a diode. For example, the first portion of the sub-fin is part of an anode of the diode, and wherein the second portion of the sub-fin is part of a cathode of the diode.

Abstract: The invention routes SVC ATM call setups by utilizing one of a plurality of designated transit lists (DTLs) stored at an originating node. The DTLs describe all routes in the network from the originating node to endpoint destinations. When a call setup message is received at the originating node, it inserts a desired DTL as an information element (IE) of the setup message. Each DTL is formatted as a concatenation of elements with each element including the node ID and output ports of each successive node in the route. Preferably, each element of the DTL includes flags such as a "process" flag which indicates whether an element of the DTL has been processed by a node, a "link up" flag which indicates that an alternative route is available between two nodes should the preferred route be down, a "bandwidth" flag which allows the alternate link to be used if the preferred link is busy, and a "last node" flag which is used in the last element of the concatenated DTL.
