Patent number: 8871105Abstract: A method is provided for etching silicon in a plasma processing chamber, having an operating pressure and an operating bias. The method includes: performing a first vertical etch in the silicon to create a hole having a first depth and a sidewall; performing a deposition of a protective layer on the sidewall; performing a second vertical etch to deepen the hole to a second depth and to create a second sidewall, the second sidewall including a first trough, a second trough and a peak, the first trough corresponding to the first sidewall, the second trough corresponding to the second sidewall, the peak being disposed between the first trough and the second trough; and performing a third etch to reduce the peak.Type: GrantFiled: March 9, 2012Date of Patent: October 28, 2014Assignee: Lam Research CorporationInventors: Jaroslaw W.

Patent number: 7601469Abstract: A plasma etching chamber of a plasma etching apparatus used in an etching process for manufacturing a photomask and a method for manufacturing a photomask using the same. The plasma etching chamber includes an electrode having a supporting surface for supporting a photomask substrate and a top surface surrounding the supporting surface, a heat transfer element installed along a peripheral edge of the supporting surface, and a heater for supplying heat to the heat transfer element. In the method for manufacturing a photomask, a shading layer is formed on a transparent substrate. A photoresist layer pattern is formed on the shading layer to partially expose the shading layer. The shading layer is etched to form a shading layer pattern, using plasma with the photoresist layer pattern as an etching mask, under a state in which the temperature of at least one portion of the peripheral edge of the transparent substrate is maintained higher than a temperature at a center of the transparent substrate.Type: GrantFiled: June 5, 2007Date of Patent: October 13, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Jeong-Yun Lee, Jin-Min Kim, Hae-Young Jeong, Young-Hwa No, Sang-Joon Yoon, Sung-Yong Cho
