Abstract
A method for manufacturing a semiconductor device formed by fractionization and division after a plurality of semiconductor elements are formed over a semiconductor substrate, includes forming a first resist portion over the semiconductor substrate prior to its fractionization. Trenches are formed in areas for dicing the semiconductor substrate. A second resin portion different in composition from the first resin portion is formed in each of the trenches. The semiconductor substrate is diced with respect to the second resin portion with widths each narrower than the trench thereby to bring the semiconductor device into fractionization and division.
Claims
exact text as granted — not AI-modified1 . A method for manufacturing a semiconductor device formed by fractionization and division after a plurality of semiconductor element are formed over a semiconductor substrate, comprising:
forming a first resist portion over the semiconductor substrate prior to its fractionization; forming trenches in areas for dicing the semiconductor substrate; forming a second resin portion different in composition from the first resin portion in each of the trenches; and dicing the semiconductor substrate with respect to the second resin portion with widths each narrower than the trench thereby to bring the semiconductor device into fractionization and division.
2 . The method according to claim 1 , wherein the second resin portion is formed by a printing system.
3 . The method according to claim 1 , wherein the second resin portion is formed by a dispense system.
4 . The method according to claim 1 , wherein a filler is contained in the second resin portion, and an average particle diameter thereof ranges from 0.2 nm or more to 40 nm or less.
5 . The method according to claim 1 , wherein a filler is contained in the second resin portion, and the content of the filler ranges from 40 mass % or more to 90 mass % or less with respect to the second resin portion.
6 . The method according to claim 1 , wherein the width of each of the trenches ranges from 5 μm or more to 30 μm or less.Cited by (0)
