They are all Co targets from two orders which showed different property as shown in the attachment. <br><div><br></div><div>For the top row, all of them surface is shinning but the sputtered ring is not perfect round shape and sharp. </div><div>For the second row, the surface is quite different from the top row. And the sputtering mark/ring is sharp and round. </div><div><br></div><div>The second picture is Ag (99.99%) targets from different company. The surface showed different property after sputtering also. </div><div><br></div><div>I guess the difference came from the different fabrication process to make the targets. Is there anyone familiar about the targets fabrication process? Will this difference affect the sputtering property? </div><div>Could you please advise which type of the targets should be ordered next time?</div><div><br></div><div>Thank you.</div><div><br></div><div><br></div><div><br></div><div>Best Regards,</div><div><br></div><div>Jing</div><div><br></div><div><div><font color="#333333" face="Helvetica Neue, Helvetica, Arial, sans-serif"><span style="font-size: 14px;">Research Lab Supervisor</span></font></div><div><font color="#333333" face="Helvetica Neue, Helvetica, Arial, sans-serif"><span style="font-size: 14px;">Nanofabrication Facility</span></font></div><div><font color="#333333" face="Helvetica Neue, Helvetica, Arial, sans-serif"><span style="font-size: 14px;">University of Houston</span></font></div><div><font color="#333333" face="Helvetica Neue, Helvetica, Arial, sans-serif"><span style="font-size: 14px;">Postal Address: </span></font></div><div><font color="#333333" face="Helvetica Neue, Helvetica, Arial, sans-serif"><span style="font-size: 14px;">UNIVERSITY OF HOUSTON</span></font></div><div><font color="#333333" face="Helvetica Neue, Helvetica, Arial, sans-serif"><span style="font-size: 14px;">NANOFABRICATION FACILITY</span></font></div><div><font color="#333333" face="Helvetica Neue, Helvetica, Arial, sans-serif"><span style="font-size: 14px;">3517 CULLEN BLVD, RM 1011</span></font></div><div><font color="#333333" face="Helvetica Neue, Helvetica, Arial, sans-serif"><span style="font-size: 14px;">HOUSTON TX 77204-5062</span></font></div><div><font color="#333333" face="Helvetica Neue, Helvetica, Arial, sans-serif"><span style="font-size: 14px;">Phone: 832-842-8822</span></font></div><div><span style="font-size: 14px; color: rgb(51, 51, 51); font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif;">Email: <a href="mailto:jguo5@central.uh.edu">jguo5@central.uh.edu</a></span></div><div><font color="#333333" face="Helvetica Neue, Helvetica, Arial, sans-serif"><span style="font-size: 14px;">Web: <a href="http://www.uh.edu/nanofab">www.uh.edu/nanofab</a></span></font></div></div><div><br></div><div><img apple-inline="yes" id="511DDD5C-61D3-4F68-8E43-B006EA3F6620" height="421" width="640" apple-width="yes" apple-height="yes" src="cid:2A56ACF0-B851-4F27-B157-F49FE6E5AD2E@uh.edu"><img apple-inline="yes" id="1E572988-C5AF-4D36-8660-D19A5910C888" height="640" width="480" apple-width="yes" apple-height="yes" src="cid:F607D494-473A-4370-9716-7DC609CE5FA3@uh.edu"></div></div></body></html>
