Definitions
- the present invention relates to an adhesive film used for manufacturing a semiconductor device such as an IC and an LSI, and a method for using the same.
- Semiconductor wafers such as silicon and gallium arsenide are manufactured in a large diameter state. This wafer is cut and separated (diced) into IC chips, and then the IC chips are mounted on a package lead frame, which is the next step.
- a die attach process also called a die bonding process
- the dicing, washing, drying, expanding, and pick-up steps are added to the semiconductor wafer in a state in which the semiconductor wafer is attached to the adhesive sheet in advance, and the semiconductor wafer is transferred to the next die bonding step.
- Such an adhesive sheet used in the process up to the pick-up process also has a sufficient adhesive force to the wafer chips up to the dicing process and the drying process, and the wafer chip at the time of pick-up. It is desired that the adhesive has a certain level of adhesive strength without adhering to the adhesive.
- the IC chip picked up in the process of Daitatsu is supplied in the form of a viscous liquid such as epoxy adhesive, polyimide adhesive, or silver paste applied to the IC chip mounting part (mount part) of the lead frame.
- Semiconductor devices are manufactured through a wire bonding process and a resin molding process. However
- a dicing tape and a dicing tape that also serve as a die attach (hereinafter, referred to as a dicing tape with a die attach film) in which an adhesive for bonding an IC chip is detachably laminated on a base film have been proposed.
- These integrated tapes require user There are many advantages as ease.
- the capacity of semiconductor devices, particularly CPUs and memories has been increasing, and as a result, the size of semiconductor devices has tended to increase.
- the memory used is becoming thinner.
- Such dicing tape is promising. Such dicing tape
- JP-A-2003-197651, JP-A-8-53655, JP-A-9-100450, JP-A-8-239636, and JP-A-10-335271 have sufficient adhesive strength to the wafer chip in the dicing process, and sufficiently satisfy the requirements for easy peeling during pickup.
