A substrate is made of a crystallized glass having translucency and an average linear thermal expansion coefficient of −5×10−7/° C. at 30 to 500° C. The substrate has a first surface (working surface) of a smooth surface having a surface roughness Rmax of less than 0.5 μm, and a second surface (non-working surface) of a rough surface having a surface roughness Rmax of 4 μm. A light shielding layer consisting of a light shielding film and an antioxidant film is formed on the second surface of the substrate through sputtering.

This ink jet application device (10) includes an optical sensor (20) and a control unit (30) . The optical sensor (20) has a light emission unit (32) which emits a detection beam (100) so as to intersect the path of travel of liquid drops, and a light reception unit (34) which receives this detection beam (100). The optical sensor (20) performs emission and reception of the detection beam (100) in at least a first position in which a portion of the detection beam (100) is intercepted by a nozzle plate (26), and a second position which is positioned lower than the nozzle plate (26) by just a distance which corresponds to the gap between the nozzle plate (26) and an object to be processed. And, on the basis of the state of light reception by the light reception unit (34), the control unit (30) detects the presence or absence of an obstruction between the light emission unit (32) and the light reception unit (34).

摘要:
Onium salts of the formula (1) are novel. R1 is C1-10 alkyl or C6-14 aryl, R2 is H or C1-6 alkyl, p is an integer of 1 to 5, q is an integer of 0 to 4, p+q=5, R3 is C1-10 alkyl or C6-14 aryl, M is a sulfur or iodine atom, and “a” is equal to 3 or 2. A chemical amplification type resist composition comprising the onium salt as a photoacid generator is suited for microfabrication, especially by deep UV lithography because of many advantages including improved resolution, minimized line width variation or shape degradation even on long-term PED, minimized defect after coating, development and stripping, and improved pattern profile after development.
