Abstract
According to one embodiment, a semiconductor device includes a device region covered with a resin film and a dicing region extending along at least one side of the device region, the dicing region including at least a first lithography mark and a second lithography mark. The resin film includes a first dicing region portion which covers a portion of the dicing region between the first lithography mark and the second lithography mark.
Claims5
A semiconductor device, comprising:
- a semiconductor substrate comprising a first device region, a second device region, and a cutting region extending between the first device region and the second device region;
- a plurality of first lithography marks in the cutting region,
- a plurality of second lithography marks in the cutting region;
- a resin covering the first and second device regions and extending into portions of the cutting region with a gap formed therebetween over a central portion of the cutting region, wherein
- the resin in the cutting region does not overlie the plurality of first lithography marks, and overlie the plurality of second lithography marks,
- the resin in the cutting region includes a first portion and a second portion that extend from the first device region, the first portion overlying a first one of the plurality of second lithography marks, and the second portion being separated from the first portion and overlying a second one of the plurality of second lithography marks,
- a side of the first portion facing the second device region is closer to the center of the cutting region than a side of the first one of the plurality of second lithography marks facing the second device region is, and
- a side of the second portion facing the second device region is closer to the center of the cutting region than a side of the second one of the plurality of second lithography marks facing the second device region is.
