Abstract: PURPOSE:To obtain semiconductor device which maintains high speed operation and provides fine Schottky barrier diodes by reducing the area of guard ring and self-alignment of the guard ring to the Schottky barrier. CONSTITUTION:A patterned negative resist film 23 is formed and the boron ion is implanted, thereafter a positive resist film 25 is formed in the area near the region other than that where the Schottky barrier diode is to be formed, only the oxide film 15 just under the negative regist film 23 exposed from the positive resist film 25 is etched by the HF gas and thereby an aperture 26 is formed, and the Schottky metal layer 28 is then formed in such aperture 26. Thereby, the P<+> type guard ring 27 and Schottky metal layer 28 are formed through self-alignment. As a result, the area of Schottky barrier can be reduced and the integration density can also be improved. Moreover, since the area of guard ring can be reduced, the junction area between the guard ring and substrate can also be reduced and accordingly deterioration of the high speed characteristic of the Schottky barrier diode can be prevented.

Title: Packet communication method
Inventor: KUNO YUTAKA
IPC: H04W24/00
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To improve the communication efficiency by deciding conditions of transition to collision control based on indices such as a data head part, an error rate of a reservation signal and number of consecutive times as factors of quality deterioration so as to distinguish a normal state from occurrence of interruption thereby preventing transition to the collision control in the case that no collection takes place and reducing a transmission delay. SOLUTION: A radio base station 1 and pluralities of mobile stations 2-1,..., 2-m are connected via a radio channel in pluralities of radio zones 10-1,..., 10-n. The radio base station 1 in each radio zone is connected to the Internet 8 via a packet exchange station 4. The mobile stations 2-1,..., 2-m send packet data when the channel is idle. The collision control in the case that packet data collide with each other is started because it is discriminated that a cause to deteriorated quality is collision only when consecutive number of times of errors over a threshold level are detected in a transmission data head part or a reservation signal sent before transmission of data at the start of communication.
