Title: Semiconductor light-receiving element
Inventor: YOSHIDA KAZUTOMI
IPC: H01L31/10
Filed: 1985-05-23
Abstract: PURPOSE:To align an optical axis easily by forming P-type, I-type and N-type semiconductor layers in the direction of the surface of a semi-insulating semiconductor base body and making a substrate electrode on the semiconductor layers and a light-receiving surface perpendicular. CONSTITUTION:Beams 12 emitted from the back of a light-emitting element 10 are projected from the surface of a P-InGaAs layer 5 or an N-InP layer 3 exposed to the side surface of a light-receiving element 11. Incident beams are absorbed in several layer, and hole-electron pairs are generated. When reverse bias is applied previously between a P electrode 6 and an N electrode 7, hole-electron pairs move by an electric field generated by an I-InGaAs layer 4, and flow through lead terminals as photocurrents, thus determining an optical output from the light-emitting element by monitoring photocurrents. Accordingly, both elements can be brought near, thus easily aligning optical axes.

Title: Manufacture of semiconductor integrated circuit device
Inventor: OGASAWARA MAKOTO
IPC: H01L21/76
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To form element isolation films which have approximately the same thicknesses on element isolation regions having different element isolation widths on the main surface of a semiconductor substrate. SOLUTION: After a selective oxidation silicon nitride film 3 deposited on a semiconductor substrate 1 is processed, an oxidation suppressing silicon nitride film 5 is provided on an element isolation region 4b having a wide element isolation width. Then the semiconductor substrate 1 is subjected to a thermal oxidation treatment to form LOCOS(local oxidation of silicon) oxide films 6 on the parts of the surface of the semiconductor substrate 1 clear of the selective oxidation silicon nitride film 3.  With this constitution, the oxidation speed of the part of the semiconductor substrate 1 surface on which the element isolation region 4b having the wide element isolation width is provided is suppressed and hence the thickness (t1 ) of the LOCOS oxide film 6 on an element isolation region 4a having a narrow element isolation width is approximately equal to the thickness (t2 ) of the LOCOS oxide film 6 on the element isolation region 4b having the wide element isolation width.
