The second photoresist is coated on the first photoresist. The second photoresist uses a positive resist of a novolac group. A contact hole inversion mask which processes a contact hole forming region by using chromium, is coated on the second photoresist and then exposed by an i-beam having a wavelength of 365 nm. The second photoresist pattern having a rod shape is formed by developing the exposed part, by using a tetramethyl ammonium hydroxide developing solution. Then, the entire structure is exposed by ultraviolet rays. The first photoresist pattern(32A) is formed by developing the first photoresist.

Title: Activation modules for obstructing entrances to inner barrels of coring tools and related coring tools and methods
Inventor: THOMAS UHLENBERG
Filed: 2017-02-25
Abstract: Activation modules for selectively sealing entrances to inner barrels of coring tools may include an activator body sized and configured to obstruct the entrance to the inner barrel when the activation module is in a first state and to release the entrance to the inner barrel when the activation module is in a second state. A sealing element may be located at a periphery of the activator body, and may be configured to form a seal between at least a portion of an interior of the inner barrel and at least a portion of an exterior of the inner barrel when the activation module is in the first state and to disengage the seal when the activation module is in the second state.
