A backside Vertical Cavity Surface Emitting Laser (VCSEL) has a substrate. A first mirror device is formed on the substrate. An active region is formed on the first mirror device. A second mirror device is formed on the active region. A pillar is formed by directional Inductive Coupled Plasma-Reactive Ion Etcher (ICP-RIE). The pillar exposes a portion of the first mirror device, the active region and the second mirror device. A first metal contact is formed over a top section of the pillar. A second metal contact is formed on the substrate. An opening formed in the second metal contact and aligned with the pillar.

A photodiode has a substrate. A mesa structure is formed on the substrate, wherein the mesa structure has an n region containing an n type dopant formed on the substrate, an intermediate region positioned on the n region and a p region formed on the intermediate region and containing a p type dopant. A contact is formed on a top surface of the mesa and attached to the p region. The contact is formed around an outer perimeter of the mesa. The mesa has a diameter of 30 um or less.

Wafer oxidation apparatus for selective oxidation of a semiconductor workpiece has an oxidation chamber. The oxidation chamber is heated by external infrared heating lamps. A chuck assembly is disposed within the oxidation chamber and configured to be approximately thermally isolated from the oxidation chamber. Carrier gas pathways deliver heated carrier gasses to the oxidation chamber at variable rates for oxidation uniformity.

A method and system for monitoring breathing movement of a subject is disclosed. A method and system for detecting and predictably estimating regular cycles of breathing movements is disclosed. Another disclosed aspect of the invention is directed to detect and report irregularity of breathing activity of an infant, such as cessation and non-periodicity, which suggests a likelihood of SIDS.

Method and system for monitoring breathing activity of a subject

A system and method for measuring and correcting the position of a patient are disclosed. According to an aspect of the invention, reference coordinates for particular body locations on the patent are determined. At a later treatment session, the relative positioning of the patient's body locations are adjusted to match the relative positioning of the reference coordinates. The entire body of the patient can thereafter be moved as a single unit to match the patient's body location with the absolute location of the reference coordinates.

Markers and systems for detecting such markers

A method and system for monitoring breathing movement of an infant is disclosed. A method and system for detecting and predictably estimating regular cycles of breathing movements is disclosed. Another disclosed aspect of the invention is directed to detect and report irregularity of breathing activity of an infant, such as cessation and non-periodicity, which suggests a likelihood of SIDS.

A method and system for physiological gating for radiation therapy is disclosed. According to an aspect, the invention comprises the use of an optical or video image system to measure regular physiological movement of a patient's body. The image data can be used to quantify voluntary or involuntary motion of the patient that may affect the delivery of radiation to a target tissue. A gating signal can be generated to suspend delivery of radiation upon certain threshold event detected in the physiological movement.
