Abstract: PROBLEM TO BE SOLVED: To improve transmission efficiency and the error rate characteristic of a demodulation signal while preventing the increase of processing delay and the limitation of a modulation system. SOLUTION: A line fluctuation estimating part 105 estimates a transmission line characteristic by using a received signal from a receiving part 102, compares the estimated transmission line characteristic with a threshold and outputs a signal on the basis of comparison results to a selector 106. The selector outputs either a 1st upper limit or a 2nd upper limit to a transmission buffering part 107 in accordance with a control signal. The part 107 outputs transmission data of a length up to the upper limit from the selector 106 to a transmitting part 108 for every packet.

IPC: H01L21/336
Filed: 1986-12-26
Abstract: PURPOSE:To prevent increase in gate capacity, by forming lowconcentration diffused layers of an MOS transistor having double diffused layer structure by means of solid phase diffusion. CONSTITUTION:A gate oxide film 12 is formed on a p-type Si substrate 11. A gate electrode 13 is formed of a polycrystalline silicon film on said gate oxide film. Insulation films are then deposited selectively on the side walls of the gate electrode 13. An oxide film 15 containing an n-type dopant is deposited all over the surface and heat treated so that the dopant of the film 15 is diffused to form n-type layers 16 (161, 162) in source and drain regions. The oxide film 15 is then removed and n-type layers 17 (171, 172) are formed in the surface of the n-type layers 16 by ion implantation. The surface of this structure is covered totally with a CVD oxide film 18, which is provided with contact holes. Source and drain ohmic electrodes 19 (191, 192) are formed in these holes. Since the low-concentration diffused layers for providing the source and drain are formed by solid phase diffusion, overlap between the source and drain diffused layers can be decreased. Accordingly, increase in gate capacity can be prevented.
