Method of producing semiconductor device

A method of producing a semiconductor device comprising the sequential steps of:

• providing a substrate made of a material easy to cleave and easy to dissolve in a preselected solvent so that film layers having excellent crystalline properties and oriented by the crystal of axis of the substrate may be made to grow on a cleavage plane of said substrate;
• vaporizing a first, metallic material-to-be-deposited to form a first vapor;
• injecting said first vapor into a vacuum region which is at most 10.sup.-2 Torr and at about 1/100 or less of the pressure of said first vapor to form aggregates of atoms of said first vapor called first clusters;
• bombarding said first clusters with electrons to ionize at least a part of said first clusters thereby forming ionized first clusters;
• accelerating said ionized first clusters by an electric field to bring them into collision with said substrate thereby forming a first, metallic film layer thereon for a terminal electrode;
• vaporizing a second material-to-be-deposited to form a second vapor;
• injecting said second vapor into a vuccum region which is at most 10.sup.-2 Torr and at about 1/100 or less of the pressure of said second vapor to form aggregates of atoms of said second vapor called second clusters;
• bombarding said second clusters with electrons to ionize at least a part of said second clusters thereby forming ionized second clusters;
• accelerating said ionized second clusters by an electric field to bring them into collision with said first metallic film layer thereby forming a second crystalline film layer thereon;
• vaporizing a third material-to-be-deposited to form a third vapor;
• injecting said third vapor into a vacuum region which is at most 10.sup.-2 Torr and at about 1/100 or less of the pressure of said third vapor to form aggregates of atoms of said third vapor called third clusters;
• bombarding said third clusters with electrons to ionize at least a part of said third clusters thereby forming ionized third clusters;
• accelerating said ionized third clusters by an electric field to bring them into collision with said second crystalline film layers to form a third crystalline film layer thereon;
• vaporizing a fourth, metallic material-to-be-deposited to form a fourth vapor;
• injecting said fourth vapor into a vacuum region which is at most 10.sup.-2 Torr and at about 1/100 or less of the pressure of said fourth vapor to form aggregates of atoms of said fourth vapor called fourth clusters;
• bombarding said fourth clusters with electrons to ionize at least a part of said fourth clusters thereby forming ionized fourth clusters;
• accelerating said ionized fourth clusters by an electric field to bring them into collision with said third crystalline film layers to form a fourth, metallic film layer for an opposite terminal electrode thereon thereby forming a laminated element film;
• and
• separating said laminated element film from said substrate by dissolving the substrate material in said preselected solvent.
