Patent ID: 7340709

Claim:
In a computer-assisted product development system comprising a processor and a storage coupled thereto, a software-implemented method for asserting design rules related to the manufacturability of optoelectronic devices comprising germanium, the method comprising the steps of: generating by the processor a data structure representing an optoelectronic device comprising germanium integrated with a CMOS device, thereby generating a set of geometrical parameters; comparing by the processor one or more geometrical parameters with a set of device design rules to generate a comparison result, adjusting the one or more geometrical parameters with respect to the comparison result, thereby improving the manufacturability of optoelectronic devices comprising germanium integrated with CMOS devices, wherein: the design rules comprise a first design rule establishing a minimum germanium window dimension in the range of 270 to 330 nanometers in an actually constructed device wherein the minimum germanium window comprises an opening in a germanium growth mask for enabling the selective deposition of germanium.
