RF Bias Function

 Combines the DC or RF sputtering and the RF etching operations. While DC or RF power is applied to the target, a small amount of RF is also applied to the substrate table. As a result, the substrate and target are both bombarded by ions ( the substrate to a lesser extent than the target ).…

RF Etch function

Essentially the reverse process of RF diode sputter deposition, in which the substrate table becomes the cathode (negative pole) and the target assembly becomes the anode (positive pole). Under these circumstances, surface material from the substrates is ejected. Surface impurities are ejected along with substrates material, making this process useful for pre-cleaning substrate prior to sputter deposition.…

Reactive Sputtering

Some metals, such as nitrides and oxides, are best deposited by this method: the target is the parent metal and a small amount of nitrogen or oxygen is introduced into the process chamber along with the argon sputtering gas. Because ionized gases are typically highly reactive, a film deposited in a mixture of argon and a reactive gas will often form a compound with the reactive gas (e.g.,…

Co-Sputtering Deposition

Sometimes called co-sputtering or dual deposition, co-deposition is identical in principle and practice to other types of sputter deposition, except that two targets (typically of different materials) are simultaneously activated. Substrates passing sequentially and repeatedly beneath the targets are coated with alternating, very thin films of two materials.…

DECLARATION REGARDING NORTH KOREAN LABOR, FORCED LABOR AND HUMAN TRAFFICKING

 PREAMBLE

On August 2, 2017, the Countering America’s Adversaries Through Sanctions Act (CAATSA), became law and restricts entry into the United States, goods made wholly or in part by North Korean labor.  Section 321(b) of CAATSA amended the North Korea Sanctions and Policy Enhancement Act of 2016 by adding a new Section 302A, which creates a rebuttable presumption that goods made wholly or in part with North Korean labor are forced labor goods.…
