Abstract:
The semiconductor chip package includes a package body with a recess and a plurality of barrier parts formed along one side thereof. Each of the barrier parts has a first region and a second region projecting from the first region, and adjacent first regions are separated by a slot. A semiconductor chip, including a reference surface having a circuit and a plurality of bonding pads formed thereon, is disposed in the recess of the package body. A conductive member is disposed in each slot, and a connecting member, associated with each bonding pad, electrically connects the associated bonding pad with a corresponding conductive member. A sealing member seals the semiconductor chip, the connecting members, and at least a portion of the conductive members in contact with the connecting members. Stacking these packages in the transverse and/or longitudinal direction further reduces their mounting area and increases the integrated capacity per unit of mounting area.
Abstract:
The present invention relates to a method of forming a gate in a stack gate flash EEPROM cell. In order to preventing a lateral bird's beak from occurring in an ONO dielectric layer during a reoxidation process to be performed after a formation of a cell gate having a stack structure formed by stacking a floating gate, an ONO dielectric layer and a control gate, an oxide layer and a nitride layer are sequentially formed on an entire structure before the reoxidation and after a formation of the cell gate. The oxide layer serves to reduce a stress in depositing the nitride layer, and the nitride layer serves to prevent an occurrence of the lateral bird's beak of the ONO dielectric layer during the reoxidation process. Accordingly, the present invention prevents the lateral bird's beak of the ONO dielectric layer, thereby improving a speed of cell erase operation.

Abstract:
This invention provides a method for determining the position range of the heart from a sequence of projection images which are acquired for 3-D volume reconstruction, such as SPECT myocardial projection data. The essence of this invention is the use of 1-D pseudo motion analysis so that the detection is insensitive to the image intensity distribution. Heart position is determined by comparing the sampled heart motion against a standard heart motion and determining similarities between the two as an indication of the position range of the sampled heart including the proximate center, upper and lower limits of motion.
