Pasted base board cutting system and base board cutting method
First Claim
1. A substrate cutting system for cutting a bonded substrate formed by bonding a first substrate and a second substrate into a plurality of cut substrates, the system for cutting a substrate of the bonded substrate comprising:
- a cutting apparatus comprising a first cutting device located so as to face the first substrate, and a second cutting device located so as to face the second substrate;
wherein the first cutting device comprises a scribing portion in which first scribing means for forming a scribing line on the first substrate is provided, the second cutting device comprises a scribing portion in which second scribing means for forming a scribing line on the second substrate is provided, the first cutting device further comprises a back up portion for supporting a surface of the first substrate when the second scribing means of the scribing portion of the second cutting device scribes the second substrate, in correspondence with the portion to be scribed, and a breaking portion for cutting the first substrate along the scribing line formed on the first substrate, and the second cutting device further comprises a back up portion for supporting a surface of the second substrate when the first scribing means of the scribing portion of the first cutting device scribes the first substrate, in correspondence with the portion to be scribed, and a breaking portion for cutting the second substrate along the scribing line formed on the second substrate.

Abstract
A cutting apparatus 400 has a first cutting device 410 located so as to face a first substrate and a second cutting device 420 located so as to face the second substrate. A cutting unit 411 includes a cutter wheel 412 for forming scribing lines on the first substrate and a breaking roller 416 which let the scribing lines penetrate through the thickness direction of the first substrate. The second cutting device 430 also includes a cutter wheel 412 for forming scribing lines on the second substrate and a breaking roller 416 which let the scribing lines penetrate through the thickness direction of the second substrate. The first cutting device 410 includes a back up roller 414 which opposes the breaking roller 416 of the second cutting device 430 and is pressed onto a surface of the first substrate. The second cutting device 430 also has a similar back up roller.

18. A substrate cutting method for cutting a bonded substrate formed by bonding a first substrate and a second substrate into a plurality of cut substrates by a substrate cutting system, wherein the substrate cutting system comprises:
-
a cutting apparatus comprising a first cutting device located so as to face the first substrate, and a second cutting device located so as to face the second substrate, and wherein the first cutting device supports a surface of the first substrate when the second substrate is scribed by the second cutting device, in correspondence with the portion to be scribed, and supports a surface of the first substrate when the second substrate is cut by breaking means of the breaking portion of the second cutting device, in correspondence with the portion to be cut, and the second cutting device supports a surface of the second substrate when the first substrate is scribed by the first cutting device, in correspondence with the portion to be scribed, and supports a surface of the second substrate when the first substrate is cut by breaking means of the breaking portion of the first cutting device, in correspondence with the portion to be cut. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
