Precision mask for deposition and a method for manufacturing the same, an electroluminescence display and a method for manufacturing the same, and electronic equipment
A precision mask for deposition is provided that includes a first brace having a plurlaity of sections placed in parallel to each other at given intervals. The first brace forms portions that define a plurality of first openings. The precision mask for deposition also includes at least one second brace that is placed on the first brace so as to intersect with the first brace. The second brace forms portions that define a plurality of second openings. The second brace is joined to the first brace at a point where the second brace intersects with the first brace.
1. A precision mask for deposition, comprising:
a first brace including a plurlaity of sections parallel to each other at given intervals, the first brace forming portions that define a plurality of first openings;
a second brace on the first brace and intersecting with the first brace;
the second brace forming portions that define a plurality of second openings; and
the second brace being joined to the first brace at a point where the second brace intersects the first brace.
2. The precision mask for deposition according to claim 1 , further comprising:
a mask substrate;
wherein the first brace and the second brace are joined to the mask substrate.
3. The precision mask for deposition according to claim 2 ,
wherein the mask substrate comprises single crystal silicon.
4. The precision mask for deposition according to claim 3 ,
wherein at least one of side surfaces of the first brace and side surfaces of the second brace is of surface orientation ( 111 ).
5. The precision mask for deposition according to claim 3 ,
wherein the mask substrate comprises single crystal silicon of surface orientation ( 110 );
side surfaces of the first brace are perpendicular ( 111 ) to surface orientation ( 110 ) of the mask substrate; and
side surfaces of the second brace are perpendicular ( 111 ) to surface orientation ( 110 ) of the mask substrate.
6. The precision mask for deposition according to claim 3 ,
wherein the mask substrate comprises single crystal silicon having an oxygen concentration of 1.7*10 18 atm/cm 3 or below.
7. A precision mask for deposition, comprising:
a first brace including a plurality of first spaced apart parallel ribs defining a plurality of first openings; and
a second brace including a plurality of second spaced apart parallel ribs defining a plurality of second openings, the first brace being joined to the second brace where the first ribs intersect the second ribs.
