Abstract:
A method provides a source-drain stressor for a semiconductor device including source and drain regions. Recesses are formed in the source and drain regions. An insulating layer covers the source and drain regions. The recesses extend through the insulating layer above the source and drain regions. An intimate mixture layer of materials A and B is provided. Portions of the intimate mixture layer are in the recesses. The portions of the intimate mixture layer have a height and a width. The height divided by the width is greater than three. A top surface of the portions of the intimate mixture layer in the recesses is free. The intimate mixture layer is reacted to form a reacted intimate mixture layer including a compound A x B y . The compound A x B y  occupies less volume than a corresponding portion of the intimate mixture layer.

Claim (Index 1):
A method for providing a source-drain stressor for a semiconductor device channel, the semiconductor device including a source region and a drain region, the method comprising:\n forming a first recess in the source region and a second recess in the drain region, an insulating layer covering the source and drain regions, the first recess extending through a first portion of the insulating layer above the source region, the second recess extending through a second portion of the insulating layer above the drain region; providing an intimate mixture layer of materials A and B, a first portion of the intimate mixture layer residing in the first recess, a second portion of the intimate mixture layer residing in the second recess, the first portion of the intimate mixture layer having a first height and a first width, the second portion of the intimate mixture layer having a second height and a second width, the first height divided by the first width being a first aspect ratio greater than three, the second height divided by the second width being a second aspect ratio greater than three, a top surface of the first and second portions of the intimate mixture layer being free; reacting the intimate mixture layer to form a reacted intimate mixture layer including a compound A x B y , the compound A x B y  occupying a volume less than an original volume of a corresponding portion of the intimate mixture layer.
