In some embodiments, a method for forming an integrated circuit is provided. The method includes forming a first layer over a semiconductor wafer, the first layer having a first portion and a second portion. The first portion is patterned by projecting a first image field over the first portion of the first layer, where the first portion of the first layer corresponds to the first image field. The second portion is patterned by projecting a second image field over the second portion of the first layer, where the second portion of the first layer corresponds to the second image field. A second layer is formed over the first layer. The second layer is patterned by projecting a third image field over the second layer, where the third image field covers a majority of the first portion and a majority of the second portion of the first layer.

Method (and related apparatus) that reduces cycle time for forming large field integrated circuits

A method of fabricating a semiconductor device is disclosed. A photosensitive material is coated over the device. A plurality of masks for a chip layout are obtained. The plurality of masks are exposed to encompass a chip area of the device using at least one reticle repeatedly. The at least one reticle is of a set of reticles. The chip area has a resultant dimension greater than a dimension of the at least one reticle. A developer is used to remove soluble portions of the photosensitive material forming a resist pattern in the chip area.

Systems and methods for fabricating semiconductor devices having larger die dimensions

The present disclosure provides a method of making an integrated circuit (IC) device. The method includes forming a first IC feature and a second IC feature in a semiconductor substrate, the first and second IC features being spaced from each other and separated by a scribe region; forming, in the semiconductor substrate, a doped routing feature at least partially within the scribe region and configured to connect the first and second IC features; forming a multilayer interconnect (MLI) structure and an interlayer dielectric (ILD) on the semiconductor substrate, wherein the MLI is configured to be absent within the scribe region; and etching the ILD and the semiconductor substrate within the scribe region to form a scribe-line trench.

Diffusion region routing for narrow scribe-line devices

In accordance with the objectives of the invention a new method is provided for the creation of a layer of a Resistance Protective Oxide (RPO) layer. A layer of ONO is deposited that is to function as the layer of RPO. The deposited layer of ONO is patterned and wet etched, removing the upper or first layer of silicon dioxide. The patterned and etch upper of first layer of silicon dioxide is used as a hardmask to remove the central layer of silicon nitride applying a wet etch. A wet etch is then applied to remove the remaining lower of second layer of silicon dioxide, completing the patterning of the layer of RPO.
