Abstract:
In accordance with some embodiments, a device includes first and second p-type transistors. The first transistor includes a first channel region including a first material of a first fin. The first transistor includes first and second epitaxial source/drain regions each in a respective first recess in the first material and on opposite sides of the first channel region. The first transistor includes a first gate stack on the first channel region. The second transistor includes a second channel region including a second material of a second fin. The second material is a different material from the first material. The second transistor includes third and fourth epitaxial source/drain regions each in a respective second recess in the second material and on opposite sides of the second channel region. The second transistor includes a second gate stack on the second channel region.

Claim (Index 13):
A method comprising:\n forming a first fin on a substrate, the first fin comprising a first crystalline material on the substrate; forming a second fin on the substrate, the second fin comprising a second crystalline material on the substrate, a material of the first crystalline material being different from a material of the second crystalline material; forming a first structure on the first crystalline material of the first fin and a second structure on the second crystalline material of the second fin; forming a first spacer along a sidewall of the first structure and a second spacer along a sidewall of the second structure; simultaneously etching the first crystalline material to form a first recess in the first fin and adjacent the first spacer, and etching the second crystalline material to form a second recess in the second fin and adjacent the second spacer, a width of the first recess at a top surface of the first fin is less than a width of the second recess at a top surface of the second fin, a depth of the first recess is greater than a depth of the second recess; and epitaxially growing a first epitaxial source/drain region in the first recess and a second source/drain region in the second recess.
