Patent ID: 7413967

Claim:
A method for forming semiconductor structures, the method comprising the steps of: (a) forming a first plurality of identical semiconductor structures, wherein each of the first plurality of identical semiconductor structures is formed by: (i) forming a first region and a second region, wherein the first region and the second region are in direct physical contact with each other via a first common interface surface, and (ii) depositing a growth material simultaneously on top of the first and second regions so as to grow a third region and a fourth region from the first and second regions, respectively, such that a second common interface surface between the third and fourth region grows from the first common interface surface, wherein the first and third regions comprise a same material and have single-crystal atoms arrangement, wherein the first region has a different atoms arrangement than the fourth region, and wherein the step of depositing the growth material is performed under a first deposition condition; then (b) determining a first yield of the first plurality of identical semiconductor structures, wherein a yield of a group of semiconductor structures is defined as a function of a percentage of satisfactory structures of the group of semiconductor structures in all the structures of the group of semiconductor structures; and then (c) if the first yield of the first plurality of identical semiconductor structures is not within a pre-specified range of a target yield, forming a second plurality of identical semiconductor structures, wherein each of the second plurality of identical semiconductor structures is formed by using steps similar to steps (a)(i) and (a)(ii), except that the step of depositing the growth material is performed under a second deposition condition different from the first deposition condition.
