Abstract

Disclosed is a method for a new splicer tool that can splice/join two or more partial tape and reels in order to produce the maximum die output of a single reel (~1000 dice/reel). Benefits include optimized speed and the ability to splice/join without damaging the die bumps.

Splicer Tool Design and Development

Disclosed is a method for a new splicer tool that can splice/join two or more partial tape and reels in order to produce the maximum die output of a single reel (~1000 dice/reel). Benefits include optimized speed and the ability to splice/join without damaging the die bumps.

Background

Currently, there is no tool in the industry that can splice/join carrier tapes with a die inside. Manual splicing is not feasible because it risks damaging the die bumps, may cause errors/jams in downstream operations, and only joins the bare carrier tape (i.e. without the die and cover tape).

General Description

The disclosed method provides a breakthrough methodology for joining two or more partial reels into a single reel that can produce a full 1000-die lot size at the Tape and Reel Die Inventory (TRDI) area (see Figure 1). In addition, the disclosed method solves Chip-Attach-Module (CAM) problems and TRDI storage space issues.

Assembly Manufacturing now has the ability to segregate dice based on Fmax-speed, power consumption, and cache-size. This new process increases yield (from existing wafer starts), reduces the waste of material used in manufacturing, and enables the mating of appropriate product according to market-segmented demands. Although this process provides enhanced manufacturing capabilities, physical die separation has resulted in an increased number of remnant partial reels (from 10% to 60%), making it difficult to manage the reel lot inv...
