Abstract
An approach forming semiconductor structure composed of one or more stacked semiconductor devices that include at least a top semiconductor device, a bottom semiconductor device under the top semiconductor, and contacts to each of the semiconductor devices. The approach provides a stacked semiconductor structure where the bottom semiconductor device is wider than the top semiconductor device. The approach also provides the stacked semiconductor structure where the width of the top semiconductor device is the same as the width of the bottom semiconductor device. The approach includes forming a contact to a side of the bottom semiconductor device when the width of the top semiconductor device is the same as the bottom semiconductor device. The approach includes forming a contact to epitaxy grown on a portion of the top and a side of the bottom semiconductor device when the bottom semiconductor device is larger than the top semiconductor device.
