Title: Determining method of critical dosage in electron beam writing
Inventor: UCHIYAMA SHINGO
IPC: H01L21/027
Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To precisely determine critical dosage, by setting a specific value of dosage wherein, in a collective pattern written and developed by changing dosage, the pattern widths of the resist surface and the bottom surface become identical in the central part of the collective pattern, as the critical dosage. SOLUTION: A collective pattern is constituted of the same rectangular repetition patterns which are arranged in a sufficiently wide region as compared with the spread of proximity effect in such a manner that the writing area ratio is 50% and translation symmetry is ensured. The collective pattern is written. Rectangles in one collective pattern are exposed with the identical dosage. After the collective pattern is written and developed by changing the dosage, a value equal to one-half of the dosage wherein, the widths of the patterns of the resist surface and the bottom surface become identical in the central part of the collective pattern is set as the critical dosage.

Title: Semiconductor photo detecting element
Inventor: TORIKAI TOSHITAKA
IPC: H01L31/109
Filed: 1983-02-03
Abstract: PURPOSE:To enable low voltage operation and enable to obtain the characteristics of high sensitivity and low noise by forming the surface of the periodical lamination of semiconductor layers in saw tooth form, and further making the projection and the recess of said lamination regions of conductivities different from each other. CONSTITUTION:A saw tooth form is formed at a part of a substrate 21 by etching the surface of the semi-insulation Inp substrate 21 doped with Fe. Next, P type Al InAs layers 22 of a forbidden band width Eg1 and N type GaInAs layers 23 of a band width Eg2 (Eg1not equal to Eg2) are alternately laminated so that both end layers become the layers 22. Then, ions are selectively implanted to the peak and the bottom of this saw tooth form lamination,thus forming N<+> layers 24 doped with a high concentration impurity and P<+> layer 25 doped with a high concentration impurity. By this constitution, since the regions 25 and 24 are intersected with each other at least in two pieces or more with a length L approximately equal to a half fiber diameter, the distance between the regions 24 and 25 can be shortened without sacrificing a photo receiving area. Therefore, an operating voltage giving an avalanche multiplying field can be decreased.
