Title: Substrate strip for ball grid array chip package structure
Inventor: HUANG CHUNG-PING
IPC: H01L23/48
Filed: 2001-03-13
Granted: 2002-01-21
Abstract: There is provided a substrate strip for ball grid array chip package structure, which has a plurality of batched substrates thereon for packaging, and is characterized in having a special connection mechanism for preventing each substrate thereon from thermal deformation in a high-temperature process. The substrate strip is characterized in using a two-point connection architecture or one-point connection architecture, instead of the conventional four-point connection architecture, to connect each substrate to the supporting rod of the frame. That is, at most two connection sheets are used to connect each substrate to the supporting rod of the frame. In a high-temperature process, the heated substrate is expanded toward the corners without the connection sheets. That is, the thermal stress is relieved toward the directions, so as to prevent the substrate from thermal deformation. Because the substrate is not deformed, the ball grid array subsequently mounted on the back of the substrate has a high coplanarity.

Title: Polarized light irradiation device
Inventor: SHINBORI MASASHI
IPC: G02B5/30
Filed: 2001-04-10
Granted: 2007-08-21
Abstract: To prevent the extinction ratio of polarized light irradiating a work from lowering even when the polarization direction of the incident polarized light on a reflection mirror is varied. Light from a lamp 1 is made incident on a polarizing element 8. Polarized light emitted by the polarizing element 8 is reflected by a second plane mirror 6 and irradiates an alignment layer of the work W via a mask M. A protective film 11 is formed on a surface of the second plane mirror 6. The kind of the protective film 11 and the optical thickness of the film is selected so as to make difference in a phase shift Delta between P polarized light component and S polarized light component emitted from the second plane mirror 6 satisfy an inequality Delta <= ±20 DEG corresponding to an incident angle and a wavelength of the polarized light. Consequently, the extinction ratio of the polarized light irradiating the work W is not lowered even when the polarization direction of the incident polarized light on the second plane mirror 6 is varied. Also, optionally the incident angle of the polarized light on the plane mirror is reduced by using a plurality of plane mirrors instead of the second plane mirror 6 or the difference in the phase shift Delta may be canceled by two sheets of plane mirrors.

Title: A rotary device
Inventor: BAE GI-SUNG
IPC: H01L21/304
Filed: 2001-06-07
Granted: 2002-09-11
Abstract: An apparatus for manufacturing a semiconductor device includes a rotatable spindle. A head detachably connected to the spindle, and a clamp for clamping outer circumferential surfaces of the spindle and the head to one another so that the head may be driven by the spindle. The clamp has an annular clamping frame sized to encircle the outer circumferential surfaces of the spindle and the head a projection disposed on one end of the clamping frame, a lever pivotally connected to the other end of the clamping frame, and a fastener pivotally connected to the lever and configured to hook over the projection. Once the fastener is hooked over the projection, the lever is pivoted to force the ends of the annular clamping frame together and thereby produce a clamping force that secures the spindle and head to one another. The clamp can be manipulated easily and with a simple motion to clamp the head to the spindle. Also, the parts of the clamp generate little mechanical friction. Accordingly, the head can be quickly connected to and disconnected from the spindle, and such operations will not produce panicles that could contaminate the semiconductor wafer.
