Title: Photomask for producing semiconductor ic
Inventor: MISU KAZUHITO
IPC: G03F1/00
Filed: 1981-04-15
Abstract: PURPOSE:To pattern only effective chips on a photomask, by preventing the peripheral margin of a silicon wafer from patterning not to leave no pieces of resist there after development. CONSTITUTION:Only the arrays of effective chips to be transferred onto a silicon wafer 1 are patterned on a photomask 3. The part of ineffective chips 4 arranged on the outside of the outermost part of effective chips are set to the light or the dark area in accordance with the kind of the photomask so as not to leave unexposed pieces of the mask 3. Since a number of chips to be stepped and repeated is depended on the sizes of the wafer 3 and the chips, it is necessary to pattern the effective chips considering this point. The size of the mask pattern 5 on the mask 3 becomes smaller than those of the conventional ones, being set to such a size as arrangeable in the range of the peripheral margin 2 of the wafer 1.

Title: Article passing detector
Inventor: NAWATA YASUSHI
IPC: G01G19/387
Filed: 1991-02-28
Abstract: PURPOSE:To detect the passing of an uncertain article whose passing orbit is accurately at a high speed in a wide detecting range. CONSTITUTION:The light emitted from a laser projecting/receiving device 20 passes through an emission hole 15, and is reflected at the prescribed position P1 of a reflection surface 13 which is formed on the inner wall of a detection hole 12 in a reflection base board 11. The light which reflects repeatedly in different reflection routes in the reflection surface 13 becomes parallel to an incident light at the 18th reflection, and is received at the laser projecting/ receiving device 20 through a receiving hole 16. When an article passes through the detection hole 12, a part of the reflection light is shut off, so the light does not return to the laser projecting/receiving device 20. It is thus possible to detect the passing of an article from a change in the receiving signal.
