Patent JP-H0444385-A (JP)
Title: Manufacture method of high frequency substrate
Inventor: SUGAWARA TAKAO
IPC: H05K1/03
Filed: 1990-06-12
Abstract: PURPOSE:To lower the value of tan delta and protect a substrate from warping or dimensional change by allowing the apparent density of a porous sheet to exceed a specified value, carrying out heat treatment for a crosslinked polymeric polyethylen sheet at or above a specified temperature, and then laminating metal foil or metal sheets on both sides or one side of this sheet. CONSTITUTION:A HMWPE porous sheet containing a cross linking agent is pressure- heated while its porous quality may be eliminated so that the apparent density of the porous sheet may exceed 80% of the genuine density. At the same time, the crosslinked polymeric polyethylene sheet obtained from cross linking processing is heat-treated at a temperature of 260 deg.C. Then, after the heat treatment, metal foil or metal sheets are laminated on both sides or one side of the sheet directly or indirectly by way of a bonding layer or a resin impregnated reinforcing layer. When the apparent density is less than 80% of the genuine density of HMWP, epsilonr or tan delta is lower and favorable, but the open cells remain so that liquid may penetrate into the sheet, which adversely affects the characteristic of a substrate where the porous quality is eliminated by a specified value and over and cross linked while the HMWP sheet is heat-treated at a temperature of 260 deg.C and over. More favorably, heat treatment is carried out at a temperature which ranges from 260 to 300 deg.C.

IPC: G01V8/14
Filed: 1981-09-28
Abstract: PURPOSE:To detect accurately a moving object independently of the state of the moving object, by detecting the reflected light of the light from a light emitting element by a photodetector through a photoconductor provided with a prescribed light receiving face. CONSTITUTION:The light from a light emitting element 3 is reflected by a moving object 1; and if the object 1 is transparent, the light is reflected by a reflector 5 to become a reflected light diverged slightly in approximately equal directions. This reflected light is detected well in a photodetector 2 through a photoconductor 6, which is provided with a large-area light receiving face 9 including the element 3, independently the state such as transparency, opaqueness, and planeness change of the moving object 1. Consequently, the moving object is detected accurately independently of the state of the moving object.

Title: X-ray exposure device
Inventor: OKADA KOICHI
IPC: H01L21/027
Filed: 1986-06-30
Abstract: PURPOSE:To prevent the breakdown and deterioration of a radiation transmitting window, and to improve reliability for a prolonged term by forming the radiation transmitting window to one part of a beam line and respectively mounting evacuating exhausting sections on the upstream side and downstream side of the transmitting window. CONSTITUTION:Emitted beams 3 introduced to a beam line 4 pass through a vibrating mirror 7 first, and pass through a radiation transmitting window 9 in a lower stream when a gate valve 8 is opened, and are lead out into atmospheric air through a radiation leading-out window 5. The radiation leading-out window 5 has a structure resisting atmospheric pressure, but the radiation transmitting window 9 fitted in front of the window 5 in order to absorb heat by emitted beams 3 hardly resists atmospheric pressure because of the main object being heat absorption. Accordingly, an evacuation section 10 having bypass structure is mounted before and behind the radiation transmitting window 9, holding the window 9, and both sides of the radiation transmitting window 9 are evacuated simultaneously on evacuation, thus extremely reducing pressure applied to the radiation transmitting window 9.

Title: Accuracy measuring pattern for pattern forming device
Inventor: NOMA AKIRA
IPC: H01L21/027
Filed: 1984-07-25
Abstract: PURPOSE:To facilitate the evaluation of accuracy of a drawn pattern by a method wherein an accuracy measuring pattern is continuously formed astriding the boundary of the adjoining small region with the pattern width and pitch approximate to the limit of resolution of a pattern forming device. CONSTITUTION:An electron beam 3 is scanned at a uniform speed in X-direction in a raster type electron beam patterning device, the ON-OFF operation of an electron beam is conducted based on the pattern data, and a patterning is performed in one scanning. An accuracy measuring pattern 10 is formed in beltlike form on the region between frames 5 and 6. Said pattern is obtained by repeatedly forming a line of 9.5mum wide, which is approximate to the limit of resolution, at the pitch of 1mum. However, if the deflection width of the electron beam 3 is short by 0.2mum per 256mum of the width W, the length of the interline A part of the boundary between the frames 5 and 6 becomes longer by 0.2mum than the length of the other interline B part, thereby generating disorder in the repetition of patterning. This disorder can be detected very easily by making observation using a miroscope of 100 magnification or thereabout.
