Title: Manufacture of field effect transistor
Inventor: SAKASHITA TOSHIHIKO
IPC: H01L29/78
Filed: 1990-10-26
Abstract: PURPOSE:To prevent deterioration of high frequency characteristics and a decrease' in a drain withstand voltage by conducting first shot of a variable shaping electron beam to a part to become a gate in exposure lower than the sensitivity of a resist, and conducting a second shot in exposure in which the exposure of the part to become the gate becomes the sensitivity of the resist. CONSTITUTION:A semiconductor insulating GaAs substrate 1 formed with a channel layer 3 is coated with electron beam sensitive resist 2, and exposed by a variable shaping electron beam 14a. Exposure D at this time is a half of sensitivity D0 of resist. Then, a shot position of a variable shaping electron beam 14b is deviated 1mum of a period from the beam 14 to be exposed. If the thus exposed resist 2 is developed, a T-shaped resist pattern is obtained. A period of the shot of the beam 14 is deviated by a half to obtain a resist pattern 32 of a gate part having a small contraction. Further, when WSi is deposited and the resist 2 is peeled by lifting OFF, a T-shaped gate electrode 5 is formed. Thus, deteriorations of high frequency characteristics and drain withstand voltage can be suppressed.

IPC: H04L5/00
Filed: 1993-10-26
Abstract: PURPOSE:To reduce waveform distortion on a bus of an inductive load by forming 1st binary data with a code representing nearly equal power to a positive and a negative pulse and forming 2nd binary data with a code representing an amplitude of nearly zero for a data code period. CONSTITUTION:Transmitters 2-4 feed a frame in which binary data (0,1) are inserted to slot parts SYN,D1-D3 of a predetermined time slot to a transmission line 1, and receivers 5, 6 connecting to the transmission line 1 receive the frame. First binary data 1 have amplitudes +P1,--P2 for one data code period and the power is represented by a nearly equal code. Furthermore, 2nd binary data 0 is made up of a code whose amplitude for one data code period is nearly 0. When the transmission code as above is used and the transmission method is applied to an inductive load, transmission waveform distortion in the transmission line having the inductive load is small by using the waveform where positive and negative pulses are consecutive and the effect of the method is maximized on a transmitter using an isolation transformer.
