Method of seeding diamond

A method of seeding for diamond film growth, comprising:

• providing a photoresist;
• providing a supply of diamond particles;
• providing a supply of binder particles for promoting adhesion of diamond film to a substrate surface;
• ultrasonically mixing said diamond particles and said binder particles with said photoresist to form a uniform mixture;
• and
• applying said mixture to said substrate surface.

A method comprising:

• providing a mixture of diamond particles, binder particles and a photoresist;
• providing an applicator configured to apply said mixture in a line;
• and
• applying said mixture in a line to a substrate surface by use of said applicator, said line having a width not exceeding about 75 microns.

A method comprising steps of:

• providing a mixture of photoresist, diamond particles having particle size of less than about 25 nanometers and binder particles;
• ultrasonically agitating the mixture to assure uniformity;
• providing an applicator and a position controlling device including a controller for controlling the movement of the applicator;
• applying the mixture to a non-planar, three-dimensional surface of a non-diamond substrate in a line having a width of about 30 microns or less with the applicator;
• patterning the photoresist to leave a pattern of the mixture on the surface;
• and
• growing the diamond particles into a doped diamond film bonded to the three-dimensional surface of the non-diamond substrate by the binder particles, the diamond film forming part of an electrical device located on the surface.
