Title: Holding mechanism for diffracting optical element
Inventor: OGUSU MAKOTO
IPC: G02B5/18
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To provide the holding mechanism for the diffracting optical element which prevents exposure light transmitted through a substrate from returning to a substrate side at the time of patterning. SOLUTION: Many needlelike projections 12 are formed on a disklike substrate chuck 11 and an airtight wall 13 is formed annularly around the needlelike projections 12. The upper end of the airtight wall 13 and the tips of the needlelike projections 12 are in same level with each other and the transparent substrate of the diffracting optical element is mounted on the tips of the airtight wall 13 and needlelike projections 12. The transparent substrate when exposed is irradiated with the exposure light from above and the light having been transmitted through the transparent substrate reaches the substrate chuck 11. The reaching exposure light L is made incident on the flanks of the needlelike projections 12 and reflected there.  At this time, the flanks of the needlelike projections 12 rise having lower parts wider obliquely to a plane parallel to the substrate surface, so the light L is reflected downward and absorbed while repeatedly reflected between the needlelike projections 12 to attenuate, so that the light will not return to the transparent substrate again.

Abstract: PURPOSE:To obtain a piezoelectric actuator which can be used for various purposes without power source restriction, and is available for miniaturization, by storing electric power in a coil constituted of high temperature superconductor, and driving a piezoelectric element by using the stored power. CONSTITUTION:A power supply terminal 4B is connected to an external power supply, and current is made to flow in a coil 5 via a controlling circuit 4. After a state where a permanent current flow is obtained, the external power supply is cut off. At this time, the coil 5 is in a superconducting state by being cooled at a temperature lower than or equal to the critical temperature. At the time of driving, the controlling circuit 4 uses the power stored in the superconducting ceramics coil 5 as a power supply, and makes the piezoceramics 2 displace according to a specified driving pattern stored in the controlling circuit 4. Thus a specified displacement is obtained. By issuing, from the outside, a command signal for displacement, arbitrary displacement also can be obtained.

Title: Photo diode
Inventor: SHIMADA MASARU
IPC: H01L31/10
Filed: 1988-02-10
Abstract: PURPOSE:To obtain a photo diode with little surface leak current without complicating manufacturing process, by forming a P-N junction by crystal growth, and forming a high impurity concentration region having a conductivity type inverse to a photo detecting part, on the peripheral part of the photo detecting part. CONSTITUTION:By crystal growth, the following are formed in order, on the surface of a P-type InP substrate 11; a P<+> InP buffer layer 12, an N<-> InGaAs light absorbing layer 13 and an N<-> InP window layer 14. From the surface side, Zn is diffused in a part except the part turning to a photo detecting part in the later process, and a P<+> region 16 is formed. After an SiN film 16 being a surface protecting film is formed on the front surface, a hole is formed on the periphery of the part to be a photo detecting part, an N<-> electrode 19 is formed which is connected, through said hole, with the semiconductor surface (the surface of the N<-> InP window layer 14), and further a P<-> electrode 18 is arranged on the rear. The greater part of P-N junctions are formed on the junction surface of the P<+> InP buffer layer 12 and the N<-> InGaAs light absorbing layer 13. Since the semiconductor layer in contact with the surface protecting film 15 is a P<+> region 16 of high impurity concentration, the influence of the interface is little, and the increase of surface leak current due to the generation of inversion layer and depletion layer can be restrained.
