Abstract:
A surface isolation device for isolating a predetermined area of a second surface of a wafer from an etching solution while the etching solution etches a first surface of the wafer to form a plurality of manifolds in the wafer. The surface isolation device has a base for positioning the wafer, a fixture for fixing the wafer on the base, and an isolation ring positioned on the base for isolating the predetermined area from the etching solution. When the fixture fixes the wafer on the base, the wafer sticks to the isolation ring, forming a seal that isolates the predetermined area from the etching solution.

Abstract:
A memory access operation on a bit cell of a digital memory, e.g., a static random access memory (SRAM), is assisted by reducing the word line control voltage for reading and boosting it for writing, thus improving data integrity. The bit cell has cross coupled inverters for storing and retrieving a logic state via bit line connections through a passing gate transistor controlled by the word line. A level of a word line signal controlling the passing gate transistor is shifted from a first voltage value to a higher second voltage value to begin a memory access cycle. The level of the word line signal is shifted from the second voltage value to a third voltage value less than the second voltage value during the access cycle. The word line signal is maintained at the third voltage value for a time interval during the access cycle.
Abstract:
The propagation delay of a signal through multiple load devices coupled sequentially along a conductor is improved by separating a subset of the load devices that is more distant from the signal source, and coupling the more distant subset to the signal through a fly-over conductor that bypasses the subset that is nearer to the signal source. The technique is applicable to subsets of bit cells in a random access memory (SRAM) coupled to a given word line, or to word line decoder gates coupled sequentially to a strobe signal, as well as other circuits wherein load devices selectable as a group can be divided into subsets by proximity to the signal source. In an SRAM layout with multiple levels, different metal deposition layers carry the conductor legs between the load devices versus the fly-over conductor bypassing the nearer subset.
Abstract:
An optical touch apparatus is disclosed. The optical touch apparatus comprises a light source emitting module, an optical module, a light sensing module, and a processing module. The optical module and the light sensing module are set around a surface of the optical touch apparatus. The light source emitting module sequentially emits scanning lights uniformly distributed above a direct scanned region of the surface according to a time sequence. When an object forms a touch point on the surface, the object will block the scanning lights and reflected lights reflected by the optical module. The light sensing module generates a sensing result according to the condition the light sensing module receives the scanning lights and the reflected lights. The processing module determines the position of the touch point according to the time sequence and the sensing result.

The data processing unit utilizes the at least one light interference signal acquired by the light module to calculate the intraocular pressure.
Abstract:
An apparatus of generating an optical tweezers with momentum and method thereof and an optical tweezers photo-image for guiding particles are provided. The apparatus generates at least one optical tweezers on an examined object that carries at least one particle. The apparatus includes a laser source, a diffractive optical element and a convergent lens. The laser beam from the laser source passes through the diffractive optical element to produce a diffractive pattern. The laser beam is then received by the convergent lens and then to be focused on a plane of the examined object. The optic axis of the convergent lens is substantially not perpendicular to the plane of the examined object, so that the laser beam is projected onto the plane of the examined object in a skewed manner for providing a lateral momentum to move the particle.
