IPC: H04L7/04
Filed: 1990-07-12
Abstract: PURPOSE:To easily receive a data even when the transmission speed from an opposite station is changed by adjusting the transmission speed to the opposite station when a transmission data from the opposite station cannot be received and setting the timing of reception of the transmission data from the opposite station again while matching the speed with the adjusted transmission speed. CONSTITUTION:When a transmission data from an opposite station is received, a reception speed detection means detects the transfer speed of the transmission data and the transmission data is sent to the opposite station at the speed in response to the transfer speed and the transmission data from the opposite station is received while matching the speed with the transfer speed. With the transmission data from the opposite station cannot be received, the transmission data is sent to the opposite station at the transfer speed adjusted and set by a transmission speed adjustment means and the transmission data from the opposite station is received while matching the speed with the transfer speed. Then the adjustment setting of the transfer speed by the transmission speed adjustment means is repeated until the transmission data from the opposite station can be received. Thus, even when the transfer speed of the transmission data from the opposite station is changed, the data is received in response to the change.

Title: Dry etching method
Inventor: NAGAYAMA TETSUJI
IPC: H01L21/3065
Filed: 1991-07-02
Abstract: PURPOSE:To simultaneously attain to the high anisotropy, rapidity and low pollusion level in the silicon trench etching step. CONSTITUTION:A wafer is cooled down at -70 deg.C to etch away a single crystal silicon substrate using Cl2/N2/S2F2 mixed gas. The etching step can be performed rapidly compared with the conventional step using Cl2/N2 base mixed gas due to F* produced from S2F2 contributing to the etching step. At this time, in addition to the production of the liberated S from S2F2, a part of this S reacts to N2 so as to produce (SN)n in polymer state having the high resistance to radical attack or ion shock. Next, these products together with SixNy, etc., are formed into a sidewall protective film 5 so as to enhance the sidewall protective effect on attaining the high anisotropy. Furthermore, S and (SN)n can be easily sublimated or decomposed to be removed by heating the wafer so as not to cause the particle pollution at all.
