Title: Manufacture of compound semiconductor device
Inventor: ONISHI TOYOKAZU
IPC: H01L29/80
Filed: 1985-04-30
Abstract: PURPOSE:To form a camel type junction or extremely shallow P-N junction under the gate electrode and to increase the barrier height, by ion-implanting a specific material into a film to serve as the gate electrode, and by diffusing it into a compound semiconductor layer by heat-treatment. CONSTITUTION:After an N-type GaAs channel region 2 is formed in a semi- insulating GaAs substrate 1, a WSix film 3 is formed. Onto the entire face of the film 3, Mg ions are implanted and patterning of the film 3 is done to form a Schottky gate electrode 3'. Next, an SiO2 film 4 is formed and an opening 4A is formed. In order to form the source region and drain region, Si atoms are introduced. After removing the film 4, an AlN film 5 is formed, serving as a protecting film for doing heat treatment. The heat treatment is done by applying a lamp annealing method. Since Mg contained in the electrode 3' is diffused extremely shallowly into the surface of the N-type GaAs channel region 2, a P-type GaAs layer 6 is formed.

Title: Method and device for evaluating crystal defect
Inventor: FUJII SHINJI
IPC: G01N27/00
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To predict where defects exist and how many defects exist by applying laser beams to a sample by scanning and measuring the amount of current flowing to the solution between the sample and an electrode. SOLUTION: In a device, a solution 6 is poured into a cell 5 and an electrode 7 is provided. Then, laser beams 3 are applied to a sample (a semiconductor substrate) 8 from a laser light source 1 by scanning, thus measuring the value of current flowing to the solution 6 between a sample 8 and the electrode 7. More specifically, when the laser beams 3 are applied to the sample 8 and if there are many defects in the crystal of the sample 8, heat conduction is prevented 1, the surface of the sample 8 is deformed due to inflation caused by the temperature increase in an application region, and the amount of deformation depends on the defect density. On the contrary, when there are less defects, heat conduction is not prevented, so that the temperature increase in the application region of the laser beams 3 is small and hence the amount of deformation is small.  The difference in the amount of deformation is captured as the change in the amount of current flowing among the electrode 7, the solution 6, and the sample 8, is measured by the current-measuring device of a workstation 10, and is displayed as the two-dimensional distribution of the defect density by an image-displaying device 11.

Title: Metal scavenger
Inventor: HOSODA KAZUO
IPC: C02F1/62
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain a metal scavenger having obviated such problems that one type of conventional metal scavenger obtained by introducing a functional group such as dithioacid group into a low-molecular amine is excellent in metal scavenging ability, but there are problems in the flocculability or sedimentability of flocs formed, while another type obtained by introducing a functional group into polyethyleneimine is good in the flocculability or sedimentability of flocs formed, but inferior in metal scavenging ability to the former metal scavengers; thus it has been difficult to afford such metal scavengers as to fully satisfy both metal scavenging ability and floc sedimentability; furthermore, conventional scavengers are subject to performance deterioration through functional group decomposition due to the presence of ant oxidizing agent and/or acidic substance. SOLUTION: This metal scavenger is obtained by reaction of a hydrazine compound with a vinylnitrile-based polymer containing >=5 mol% of nitrile group-bearing polymer unit component to effect introduction of amidino group serving as functional group into the nitrile group portion of the vinylnitrile-based polymer; or this scavenger bears metal-scavenging functional group introduced through substitution with at least one hydrogen atom bond to the nitrogen atom of the above amidino group.
