Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To realize a field effect transistor which is enhanced in reliability without deteriorating in high-frequency characteristics under operating conditions such as a high applied-voltage, a large current, and high temperature by a method wherein recesses are varied in depth in the direction of gate fingers so as to make a threshold voltage low at the center and high at edges in the direction of the gate fingers. SOLUTION: A region where a source electrode 9 and a drain electrode are formed is opened on a semi-insulating GaAs substrate 1. Then, Si ions are implanted to form an N<+> -GaAs region 5. An operation opening is formed of resist, and the first implantation of Si ion is performed. Then, a pattern used for opening only operating layers each located at the edges of a comb- shaped gate is formed of resist, and the second ion implantation of Si ions is carried out.

Title: Manufacture of semiconductor device
Inventor: MATSUKURA YUSUKE
IPC: H01L21/3065
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To conduct highly selective etching even at low gas pressure by a method wherein the rise in temperature of the electron in plasma is suppressed, using an etching gas which contains chlorine-containing gas and fluorine- containing gas. SOLUTION: A compound semiconductor substrate 16 is placed on a holder 14 using an inductively coupled device 10, for example, as a low voltage and high density plasma etching device. Then, an etching chamber 12 is evacuated. Next, SiCl4 gas and SF6 gas are introduced into the etching chamber, for example at a flow rate ratio of 1:4 the speed of evacuation of the etching chamber is adjusted, and gas pressure is adjusted to 0.1 Pa. Subsequently, since electricity is discharged by supplying power to accelerate discharge to a pulse-modulated antenna 18, the temperature of electrons drops when an applied voltage is turned off intermittently, and the electron temperature can be suppressed low.  A compound semiconductor can be etched with high selectivity even at a low gas pressure, because the compound semiconductor layer is etched, while its temperature rise is being suppressed using pulse modulated plasma.

Title: Scanning tunnel microscope
Inventor: WAKASUGI HIROYUKI
IPC: G01B7/34
Filed: 1992-10-05
Abstract: PURPOSE:To move a sample by an optional amount in the X direction by setting divided electrodes to an outside piezoelectric bobbin and forming a table for mounting the sample thereon in the structure of upper and lower two stages with a guide groove. CONSTITUTION:The same sawtooth voltage is impressed to the whole of the quadrant electrodes 4b, 4c of an outside piezoelectric bobbin 4 thereby to separate a sample 10 from a probe 6. When sawtooth voltages of opposite phases are added to the electrodes 4b in the X direction, an upper table 9b holding the sample 10 is moved in the X direction while accompanying a stick slip. In other words, when the bobbin 4 is curved in tone X negative direction instantaneously, the table 9b slips and never moves. On the other hand, when the bobbin 4 is curved in the X positive direction slowly, the table 9b is moved in the X positive direction together with a lower table 9a by the friction force. As the above process is repeated, tone table 9b is gradually moved in tone X positive direction. The movement of the table in the X direction of the bobbin 4 is stopped when an end of the probe 6 is brought to a to-be-observed part of the sample through another optical microscope. In this manner, a wide scanning range in the X direction is achieved.
