sequentially to $38 million driven by robust demand from the LED market. The Company continues to add capacity in order to serve this rapidly growing market. Parvez continued, “Our customer base continues to grow and we are aggressively adding capacity to meet their needs.”


The Company reported continued strong interest for its polished six inch wafers. Parvez continued, “While we were capacity constrained in the first quarter, we expect a significant increase in revenue from six inch polished wafer sales in the second quarter.”


Second Quarter 2011 Guidance


Commenting on the outlook for the second quarter of 2011, William Weissman, Rubicon’s Chief Financial Officer said, “We expect continued strong demand resulting in revenue increasing to between $40 million and $43 million. We have projected overall substrate pricing in the second quarter to be slightly lower than first quarter pricing due to some reduction in the price of two inch core products. We anticipate gross margin to be in the high fifty percent range in the second quarter with diluted earnings per share of between $0.82 and $0.86. This assumes a diluted share count of 24 million shares and a tax rate of 7 %, which represents accrual for state income taxes only.”


Parvez continued, “Each quarter we evaluate our tax valuation allowance and determine whether it is appropriate to begin accruing for federal income taxes for financial statement purposes. That determination is made after evaluating many factors, including the projected earnings for the full year. It is possible that we may release the tax allowance and begin accruing federal taxes in the second quarter. If that were the case, we estimate that our total federal and state effective tax rate for financial statement purposes for the last three quarters of this year to be approximately 40 %. It is important to note that our projected tax rate for 2012 remains at our previously provided rate of 30 to 35 %. In addition, our projected cash basis tax rate for 2011 remains low at approximately 10 percent despite our increased earnings.”


Keithley launches power system meter for CS device characterisation


The “breakthrough” 2651A can characterise GaN, SIC, and other compound semiconductor materials and devices and provide data on semiconductor junction temperature characteristics.


Keithley has introduced the 2651A High Power System SourceMetre Instrument which it claims offers breakthrough capabilities for testing the latest high power electronics, semiconductors, and materials.


The 2651A instrument addresses a wide range of applications including power semiconductor, HBLED, and optical device characterisation and testing. It can also characterise GaN, SIC, and other compound semiconductor materials and devices and provide data on semiconductor junction temperature characteristics. Operating at a high speed and with high precision digitisation, it is capable of high current and high power device testing and can also be used for electromigration studies.


With a broad dynamic range, the machine has the ability to source or sink up to 2,000W of pulsed power (±40V, ±50A), or 200W of DC power (±10V@±20A, ±20V@±10A, ±40V@±5A).
