摘要: Methods for fabrication of magnetic write heads, and more specifically to fabrication of magnetic poles and trailing magnetic pole steps. A write pole may first be patterned on a substrate. Then a side gap material may be patterned along sidewall portions of the write pole. Thereafter, a masking layer may be deposited and patterned to expose a portion of the write pole. A trailing magnetic pole step may be formed on the exposed portion of the write pole.

摘要: Methods for fabricating a device component are provided. A substrate comprising a RIE stop layer, an oxide layer formed on the RIE stop layer, and a RIE-able layer formed on the oxide layer may be provided. A resist layer may be patterned on the RIE-able layer. A metal layer may be formed on portions of the RIE-able layer that are not covered by the resist layer. The resist layer may be removed and an RIE performed to remove exposed portions of the RIE-able layer and portions of the oxide layer beneath the exposed portions of the RIE-able layer. Thereafter, the metal layer may be removed, and the component may be formed in an opening in the oxide layer formed during the RIE.
