Title: Light emitting semiconductor
Inventor: NISHIZAWA JIYUNICHI
IPC: H01L21/22
Filed: 1979-05-28
Abstract: PURPOSE:To obtain an LED having no interfering property by stacking a layer with the same conduction type as a III-V-group semiconductor substrate, and the second  and third layers with the second conduction type and different carrier densities but  with the same composition on said III-V-group semiconductor substrate, and by controlling the carrier densities of the second and third layers. CONSTITUTION:An n-type layer is directly stacked on an n<+>-type III-V-group semiconductor substrate, the second and third p-type layers whose carrier densities are n2 and n3 are stacked, and the densities are kept such that n3>2.5n2. The height of the potential barrier resulted from the difference in densities becomes greater than kT, and the carriers cannot go over said barrier. Furthermore, n3<2X10<19>cm<-3> is specified, and the increase in nonlight emitting centers due to the generation of the defects in the vicinity of the boundaries between the layers is suppressed. In this  constitution, the LED having excellent light emitting efficiency can be obtained. If  the second and third layers are of n-type, the adjustment is made to obtain an n3< 2X10<18>cm<-3>.

Filed: 1986-03-25
Abstract: PURPOSE:To enable a wafer to be exposed in a correctly registered position, by irradiation registering marks by means of a light irradiating means for eliminating errors in detecting positions of marks caused by the presence of photoresist. CONSTITUTION:Light from an excimer laser source 11 travels via an aperture member 12, a luminous energy regulating mechanism 17 provided by a switchable ND filter and relay lens 13 and enters a roof prism 5 through a retractable mirror 8. The light is divided by the roof prism 5 into two oppositely directed rays and applied to registering marks 16a-1 and 16a-2 on the top face of a wafer 16. The luminous energy of the light from the light source 11 is regulated by a luminous energy regulating mechanism 17 for each resist. Photoresist applied on the registering marks and on the periphery thereof can be removed thereby. Since photoresist in the proximity of the registering marks has been removed, the wafer can be scanned by an argon ion laser beam 1 with the retractable mirror positioned as indicated by the broken lines without errors in detecting positions due to nonuniformity in the photoresist layer and without shortage of scattered light due to the photoresist absorbing light.
