Abstract: A semiconductor device has source and drain regions, a gate insulating film, a gate electrode, and a channel region. The channel region includes a region where carriers move between the source and drain regions. An impurity concentration of the channel region is higher at an end portion of a surface depletion layer than at an interface between the semiconductor layer and the gate insulating film. The impurity concentration varies along a direction in which the gate electrode, the gate insulating film and the channel region are successively provided, and it increases substantially linearly near the end portion of the surface depletion layer.

Abstract: The present invention provides a method for manufacturing a semiconductor device without the use of an anti-reflective coating. In one embodiment, electrical devices are formed on a semiconductor substrate. A material with a low dielectric constant such as an oxide is then deposited. The low dielectric layer is then covered with photoresist and photolithographically processed and subsequently developed. The low dielectric layer is then etched using the pattern formed on the photoresist and the photoresist is later removed. Because this process works in any similar circumstances, good examples of its application are the formation of both contacts and local interconnects.

Abstract: A bridge that can effectively use plural paths by restricting a single path by a spanning tree algorithm, thus preventing that a broadcast packet is circulated in a looped communication path when two neighbor brides configuring a spanning tree are physically connected with plural paths. The bridge incorporates a correspondence table for the correspondence between the transmission source Mac address and the transmission destination port of a packet. A transmission source Mac address registration section decides the transmission destination port of a packet to be transmitted from the port to other bridge. The transmission destination port is cataloged on the table. When the transmission packet is a broadcast packet or BPDU packet, it is divided to a specific port among ports of the bridge. Other packets are divided to the corresponding ports by referring to the content cataloged on the table. Thus all the paths can be effectively used.

Abstract: The present invention further provides a method for forming self-aligned contacts using a dual damascene techniques that reduces the number of process steps and results in a reduction in cycle time, cost and yield loss.

The contact and channel are formed by (1) forming a contact opening in the dielectric layer, (2) forming a channel opening in the dielectric layer, wherein the channel opening encompasses the contact opening, (3) extending the contact opening to expose a portion of the region on the semiconductor substrate; and (4) filling the contact opening and the channel opening with a conductive material to form a contact and a channel, respectively.

Abstract: The present invention provides a method for manufacturing a semiconductor device with an anti-reflective coating (ARC) that does not need to be removed. In one embodiment, electrical devices are formed on a semiconductor substrate. A dielectric layer is then deposited over the electrical devices and the semiconductor substrate, upon which an optically transparent ARC layer of low dielectric constant is then deposited. Photoresist is then deposited on top of the ARC layer and is then photolithographically processed and subsequently developed. The dielectric layer is then etched down to the semiconductor substrate to form contacts or local interconnects. The ARC layer can subsequently be used as a hard mask and does not require removal.
